Brackman ABSTRACT Construction costs in the Georgia Coastal Platn are probably higher than they could be because most of the coarse construction aggregate used there (prtmartlycrushed stone) is transported from the Piedmont Province. The purpose of this report is to provide an evaluation of the construction materlal of the middle third of the Coastal Platn, approximately 11,000 square mlles. The study area covers all of twenty-three counties (Atkinson, Ben H111, Berrien, Bleckley, Clinch, Coffee, Dodge, Echols, IIWin, Jeff Davis, Johnson, Lamer, Laurens, Montgomery, Pulaski, Telfair, Treutlen, Twiggs, Ware, Washington, Wheeler, Wilcox, and Wilkinson): and covers parts oftwelve counties: Baldwin, Hancock, and Jones are not entirely within the Coastal Plain: Cook, Crisp, Dooly, Houston, Lowndes, Peach, Tift. and Turner were partially covered in GGS Bulletin 106, (Frlddell 1987]: Bibb County is in both of these catagories. Sites within the study area were prioritized as to their potential for aggregate production based on the: 1) soil type present: 2) proximity to sand or gravel pits described in both published and unpublished literature: 3) geomorphic features indicative of aggregate deposits: and 4) proxlmity to active or recently inactive conunercial mining operations. Four counties (Baldwin, Echols, Hancock, and Pulaski) were found to have moderate to high potential for aggregate production. ACKNOWLEDGEMENTS The author would like to extend her gratitude to those who painstakingly reviewed this manuscript. These people include Brian Thames, Bruce O'Connor, and Mike Frlddell (who also provided much needed advice from time to time) of the Geologic Survey: Bob Dickerson of the Georgia Department of Transportation: and Bob Carver of the University of Georgia. Thanks also to Mike Laney, Tony McCook and Scott Setser of the Geologic Survey for invaluable field assistance. Appreciation also goes to the cartographic and editorial staff of the Geologic Survey. INTRODUCTION The first ofthis three part study, Bulletin 106 (Frlddell, 1987, see Figure 1), covered the western third of the Coastal Plain, the area west of Interstate 75. The second part, Bulletin 108 (Frlddell and Brackman, 1990), evaluated the potentlal construction aggregate reserves in the eastern third of the Coastal Plain. Aggregate, as defined by industry, is composed of unconsolidated rock particles. Fine aggregate ranges from 0.075 nun to 4. 75 nun in size, and coarse aggregate ranges in size from 4.75 nun to 3.5 inches (8.89nun). Uses for construction aggregate include concrete, mortar, plaster, brick, masonry sand and fill material. Mining ofsand and gravel in this area of the State 1s done primarily by back-hoe and front-end loader. PURPOSE AND SCOPE PurPOSe Within the Coastal Plain ofGeorgia, construction costs are higherthan in otherparts ofthe State because coarse aggregate must be transported great distances. Therefore,identtficationofadequate aggregate reserves located in the Coastal Plain, probably, could lower construction costs. The purpose of this study is to evaluate the aggregate production potential of the central third of the Coastal Plain by studying the resources available, and locating favorable areas for aggregate production. Because it is not always possible to anticipate the geographic areas in which the demand for aggregate may occur, demographic divisions were not considered, thus, providing a better indication ofthe true availability ofboth fine and coarse aggregate deposits. 1 '\'''''uoo t , .... {J ' \ .. l"' I \ ' \"'" <1" ' N L.. n-"-.- - - t. -- - ,--- - " ' 1"il,l;t.'\, "1\ II I'' ,, u ' / "&HI \ -\ N t 10 MILES . ... ,. .1--- ,,. \ r pr"tA[THEQ 11 '- t t \--- ( .

Location map of the study area. 2 Scope The study area is that part ofthe Coastal Plain Province of Georgia that lies east oflnterstate 75, and west of a ltne drawn north to south along the easternborders ofWashington, Johnson,Treutlen, Montgomecy, Jeff Davis, Coffee, and Ware counties. This area encompasses approximately 11 ,000 square miles and includes the entirety of twentythree counties, with partial coverage of twelve others. PREVIOUS WORK The major previous work concerning sand and gravel exploration and evaluation in Georgia is that of Teas (1921). Teas performed a thorough sutvey of sand and gravel resources of the entire State. The Department of Natural Resources. Environmental Protection Division of Georgia maintatnsa record ofsutfacemtning andlandreclamation activities which is updated yearly. This listing includes information on sutface mintng activities permitted since Januacy 1, 1969. The information includes the product mined. operator. location of operation. acres permitted, acres reclaimed. and the status of the operation (whether active or inactive). Steele and O'Connor (1987) identified the mtntng operations in Georgia. This publication lists the mtneral commodities by county. producers' names. and the plant locations. An evaluation of the construction material potential of the eastern and western thirds of the Coastal Plain have been evaluated by Friddell (1987) and Friddell and Brackman (1990). respectively. PHYSIOGRAPHY The study area lies within the Coastal Plain Province ofGeorgia. Six physiographic districts are present in the study area; they are the Fall Une Hills, Vidalia Upland, Bacon Terraces. Okefenokee Basin. Fort Valley Plateau, and Tlfton Upland Distrtcts (Figure 2). Clark and Zisa (1976) described these districts as follows: "Fall Line Hills Dlslrict- The Fall Line is the northern boundary of this district.... Geologically, tt is the contactbetweenthe Cretaceous andyounger sediments of the Coastal Plain and the older, crystalline rocks of the Piedmont. Several stream characteristics change as they flow south through this area: rapids and shoals are common near the geologic contact, floodplainS are considerably wider on the younger sediments and the frequency of stream meanders increases....The southern boundary then closely follows the northernmost occurrence of .the undifferentiated Neogene geologic unit which underlies the Vidalia Upland. The Fall Line Hills District is highly dissected with little levelland except the marshy floodplains and their better drained, narrow stream terraces. Stream valleys lie 50 to 250 feet below the adjacent ridge tops... Relief gradually diminishes to the south and east. Maximum elevations are approximately 760 feet between Columbus and Macon and gradually d1mtnish to a mtn1mum elevation of 150 feet south ofAugusta. "Fort Valley Plateau District- (The Fort Valley Plateau District)... is characterized by flat-topped interfluves with narrow, 50-150 feet deep. steepwalled valleys. This area is distinct from the Fall Line Hills in that the broad. flat-topped interfluves are the dominant feature, there are fewer streams, and there is less local relief. The area is less dissected than the Fall Line Hills because it 1s underlain by the more clayey units of undilferentiated Eocene. Paleocene and possible Cretaceous age sediments. Elevations range from 550 feet in the north to 250 feet in the southeast, indicating a soulheast regional dip. "'Tifton Upland District - A well developed. extended. dendritic dratnage pattern is formed on the undi1Terentiated Neogene sediments In the Tifton Upland District. Characteristically, the interfluves are narrow and rounded, rising 50 to 200 feet above the narrow valley floors. Elevations range from 480 feet in the norlh to 150 feet in the southeast. indicating the regional slope." "Vidalia Upland District -The Vidalia Upland District is a moderately dissected area with a well developed dendritic stream pattern on gravelly, clayey sands. Floodplalns are narrow except along the principal rivers which have a wide expanse of swamp bordering both sides of the channel. Relief varies from 100 to 150 feet. Elevations in the district range from 500 feet in the northwest to 100 feet in the southeast indicating the regional dip. The northern and northwestern boundary approximates the northernmost occurrence of the undlfferentiated Neogene geologic unit. The southwestern and southern boundary 1s the base of the Pelham Escarpment and the southern drainage divide of the Altamaha River. The southeastern boundary follows the Orangeburg Escarpment at approximately the 150 foot eleva- 3 N t Fort Valley Province \- / /'-_"'I. I -"' S 0 N ~ 'f' Ot:===j20~~~~40.

The escarpment rises 50-70 feet above the Barrier Island Sequence District. "BaconTerraces District- Several moderately dissected terraces, generally parallel to the present coastline, are detectable on topographic maps of theBaconTerracesDistrict. However, theyarevery difficult to observe on the ground because the east facing scarps are very subtle. The terrace levels occur at elevations of 330-310 feet, 295-275 feet, 265-255 feet, 240 feet, 230 feet, 215-190 feet, and 180-160 feet. This district. on the north, west, and south, corresponds to the Satllla River drainage basin with its boundaries on the basin divide. The eastern boundary is the western base ofTrail Ridge at approximately the 150 foot elevation. The southeast-trending, very extended, dendritic drainage pattern has formed on Upper Tertiary sediments. "Okefenokee Basin District - Low relief, decreasing to the southeast, and numerous swamps are characteristic ofthe Okefenokee Basin District. Relief varies from approximately 50 feet to less than 5 feet. Elevations in the district range from 240 feet in the northwest on Pliocene-Pleistocene deposits to 75 feet in the southeast on Pleistocene deposits... At the extreme southern end of the district the St. Marys River turns east and flows through a gap in Trail Ridge. The northern and westernboundaries ofthe district coincide with the northernand westernboundariesofthe Suwannee River. The eastern boundary is the western base ofTrail Ridge. GEOLOGY The geology of the study area is illustrated in Figure 3. This section contains briefdescriptions of units cropping out in the study area. Quaternary alluvium Quaternary alluvia consist of unconsolidated sediments, found infloodplains of rivers and streams, and eolian sand dunes alongmajorrivers and streams of the study area. Altam&ha Formation The Altamaha Formation is Miocene to Pliocene in age (Huddlestun, pers. comm.); and, according to Friddell (1987, p. 10), "consists of thinto thick-bedded, locally cross-bedded, variably indurated, well-to poorly-sorted, feldspathic, argilla- ceous,locallygravelly. fine- to coarse-grained sand to clay." Oll,ocene sediments These Oligocene sediments are primarily composed of limestone and dolostone. Barnwell Group Sediments of the Barnwell Group are Late Eocene in age; and, according to Huddlestun and Hetrick (1985, p. 16-17), are predominately composed of very fine-to very coarse-grained quartz sand in thin to thick, horizontally-bedded layers. Marshallville Formation According to Hetrick (1991), the Marshallville Formation consists of fine- to medium-grained sand interlayered with clay. Generally, the Marshallville Formation crops out as channel deposits of fine-grained sand and clay. The Marshallville also occurs as thin to thick beds of cross-bedded, fine- to medium-grained sands. These sediments are Paleocene in age. Oconee Group Sediments of the Oconee Group are Upper Cretaceous to Tertiary in age and consist pr1marily of kaolin, kaolinitic sand, and mica, with minor amounts of heavy minerals present in mediumgrained sand (Hetrick and Frtddell, 1990). Hawthorne Group In the study area, the Hawthorne Group is represented by the Statenville, Cypresshead, and Miccosukee Formations (Huddlestun 1988, p. 9296, p. 119-129, respectively). Statenville Formation The Statenville Formation, middle Miocene 1n age, consists of cross-bedded "argillaceous, dolomitic, phosphatic sand." It is predominately composed of fine- to coarse-grained well- to poorlysorted quartz sand.

For detailed description, see text. Figure 3. Geologic map of the study area. 6 age, consists prtmarJly of quartz sand, including some "pebbles and gravel, heavy minerals, mica, trace fossils..." Miccosukee Fonnation The Miccosukee Formation, late Pliocene in age, is plimartly composed ofsand, with clay being predominant in certain areas. The Miccosukee is usually found in thin beds of fine-to mediumgrained sand, and locally. is found occurring as scour and fill structures filled with coarse-grained sediments and gravel stringers. PROCEDURES AND :METHODS neBneation ofAreg with Potential for ~2ate Procluctlon Areaswere prioritizedbased on four factors: 1) soil type: 2) proxfmity to known sand or gravel localities: 3) prox1mity to known sand or gravel m1n1ng operations: and 4) geomorphic features present. Soil Type The soil associations used in targeting areas for potentlal aggregate production were selected from two types of county soil surveys: 1) detailed 1:20,000 scale, photographic based soil surveys published by the United States Department of Agriculture Soil Conservation Service in coopera- tion with the University of Georgia College ofAgri- culture: and, 2) generalized 1:63,360 scale maps on file at the Georgia Geologic Survey, produced by the Georgia Department of Natural Resources' Office of Planning and Research. The detailed, photographicbase surveyswere preferred: however, these were not available for all counties in the study area (Figure 4). After reviewing the published grain sfze data of each county survey for the soil or soils which contained the coarsest sand and the least amount of fine material (<#200 mesh), the following soil associationswere chosenfrom the detailed surveys: Alapaha, Fuquay, Kershaw, Lakeland, Mascotte, Paola, Rutlege, and Troup: and these from the generalized maps: #24 - Chipley, Kershaw, Lake- land: #39- Fuquay, Lakeland: and #41 -Alapaha, Mascotte, Rutlege. Following the selection of soil types, their areal extent was plotted on 1:24,000 scale topographic maps. Sand and Gravel Localities The locations of gravel pits, sand pits, and prospects on file at the Georgia Geologic Survey, as well as localities discussed by Teas (1921), were plotted on 1:24,000 scale topographic maps. In some cases, Teas (1921) localities could not be accurately located on modem maps and were not included. Sand or Gravel Producers The Department of Natural Resources, Environmental Protection Division, Office of Surface Mining and Land Reclamation maintains a listing ofactive orrecentlyinactive (since 1969) commercial aggregate mines in Georgia. These were checked against the listing in the Mining Directory of Georgia (Steele and O'Connor, 1987) published by the Georgia Geologic Survey. The locations were then plotted on the 1:24,000 scale topographic maps used in this study. Finally, a field surveywas carried out to verifY and update this information and to gather data on the mining operations. Geomorphic Features Each topographic map was visuallyinspected for geomorphic features such as point bars, river terraces and dune complexes that are generally associated with sand and gravel deposits. Point bars were identified by their general lack of vegetation, flat to undulating surface, and their orientation on the convex side of stream banks. Terraces (former valley floors) were identified by their generally flat surface and their proxfmity to present day streams. Dune fields were recognized as being hills present generally along the north and east sides of major streams. The areal extent of these features was outlined on the 1:24,000 scale topographic maps. Assloment of Priorities In order to assign a rank to different areas for aggregate potential, numerical values were assigned on the basis of the four ranking factors. A value of one (1) was assigned to a site where one of the variables existed: a value of two (2) was assigned where two factors overlap. In sfmilar fashion, the overlap of three variables produce a value of three 7 N ' t ""' WASHINGTON I \ I /' - ~ TWIGGS\ / ~ _.-.;(::";~:~T::::T:-_"1-{( .r--1~,:-il'f:: .~1lrlf''t~~~i! -~'CH t.... -.. , ~ , ( I I HO U S T O~I'N\Y.,~-A :~,..r,,::,.:.~-e-~'~~'.~:'.'Kr-~'~"~"\'.S;.;~--'i.(~:',:~:~.~:.1.;-..'~::;:L1.;:A~~:-:U~?IR~-:'.E.:.;.;N:.~'-".!S/.t":~-:.~-:~"_<,~..~-:,~'r-~-:,:~~.<;'~!~';;y.>~';-P-~ D Counties with detailed 1:20,000 scale soil surveys from the United States Department of Agriculture.

Plate I (see pocket). which shows the potential for aggregate production. Js a compilation of the Information plotted on the 1:24,000 scale topographic maps. Interpretation of what constitutes an area ofpotential for construction materials may have changed slightly from sJmilar work done for the Southwestern Coastal Plain (F'Iiddell, 1987) and for the Eastern Coastal Plain (Friddell and Braclanan, 1990). These difierences are due to improvements 1n the database. The plates which show th1s potential for these three studies may not match up exactly; however, consistency within each study is assured. Samplln& Areas were sampled in order to field check the Information compiled and to evaluate these areas for aggregate production. Accessible areas wilhin each county with high (two or greater. when possible) assigned values for aggregate potential were examined: and, if the areas appem.-ed lo have potential aggregate value based on field observations. they were sampled. The sampling method, as described below. was designed to insure that the samples collectedwould show a true representation ofthe actual material present. Sediment samples were gathered by either auger or trenching. When possible, sampling was carried out by the use of a truck-mounted Gidding's soil probe equipped with a 4.5" spiral auger. Alternate methods of sampling included trenching, when a natural exposure was encountered, or hand augertng when sampling a point bar in a river. Auger At most localities. samplingwas carried out by the use of a truck-mounted Gidding's soil probe, equipped with a 4.5" spiral auger. The depth of the auger holes varied and depended upon the point at which either the auger could not penetrate the sediment or the sample could not be retrieved. Samples could not be retrieved from below the water table or, in some cases, from clay or clayey sand. At the completion of each four-foot auger run, one-third of the material retained on each flight was retrieved, examined. described, and placed in a labeled sample bag. If, at any sample locality, an appreciable change In grain-size was notiCed, a new sample was begun and so deSignated. At localities where 1t was not possible to use the Gidding's Soil Probe, such as a sand bar accessible only by boat, a hand augered sample was taken. Trench Some localities, such as gullies or road cuts, offered a natural exposure that made augertng unnecessary. At such localitiestrenching provided an adequate sample. The surface of the face to be sampled was cleaned to a depth of approximately one inch and a trench ofapproximately three to six inches wide was cut into the face. The sample was then collected, examined, described, and placed in a labeled sample bag. As was the casewith augered samples, when an appreciable change in grain size was noted, a new sample was begun and so designated. Sample Identification Each sample of this report is identified by an abbreviation ofthe name ofthe county in which the sample was taken and is numbered consecutively within each county. In the event that more than one sample was taken from a single site, an alphabetical suffix was attached to each sample designation. startingwith "a" for the stratigraphically highestsample. Thus, Dod-4a andDod-4brepresent two samplesfrom the fourth sampletaken inDodge County: Dod-4abeing the first sample taken at this site. LABORATORY PROCEDURES In lhe laboratory, the samples were placed in a drying oven at 230 degrees Fahrenheit for 24 hours. After drying, the samples containing very coarse material were sieved through a 3/8" sieve and were separated from the other samples. Laboratory procedures continued as described below. Particles larger than 3/8" For those samples which contained particles greater than 3/8," the entire sample was weighed and then sieved through 3/4," 1/2," and 3/8" sieves. Particles retained on these sieves were brushed free of clay and fine sand. This finergrained material was returned to the bulk sample. 9 The nominal diameter of the particles retained on the 3/4" sieve was measured using calipers. Following this, the weight of each categozy was recorded. The remainder ofthe sample was analyzed in the same manner as the samples conta:in.ing no particles greater than 3/8" (see following section). Followtng the sieving of the finer fractions, the weight percentage for each sample was calculated using the method of Folk (1974, p. 34-35). Particles smaller than 3/8" After dzylng, each sample was split, using a mechanical splltter.until a sample size of approximately 150grams was obtained. This material was weighed and the weight recorded. The sample was then washed on a #200 mesh sieve until the water ran clear. The split was placed in the dzying oven at 230 Fahrenhe~t and left overnight. After drying. the sample was reweighed and this washed weight recorded. The dzy sample was then sieved mechanically for approximately 15 minutes, using a Ro-Tap machine and a nest of sieves consisting of 414, #8, 1116, #30, #50. # 100, and #200 mesh. After dzy sieving, the weight retained on each sieve was recorded and the weight ofthe material retained in the pan (less than #200 mesh) was added to the calculated weight ofthe <#200 mesh fraction. The weight percent passing for each fraction was then calculated. EVALUATION OF THE SIEVE DATA The siZe distribution curves were analyzed according to A.S1M Standard C-33, the standard for a fine aggregate (Table 1) . In normal commercial processing of aggregate material, the fine-sized material is removed duringwashing and screening; thus, some material that ls naturally substandard is upgraded to a producl that meets commonly accepted standards such as those of the American Society of Testing Materials (ASTM). Some of the samples are mixtures of fine and coarse material. and, thus. do not meet ASTM standards for either fine 'or coarse aggregate. Because such mixtures can be processed to produce aggregate that meets AST.M: Standard C-33, these samples are discussed in some detail in the text. Although the major purpose ofthis study is to analyze sediments of the Coastal Plain for aggregate potential. the majority ofmatertalsintheirnaturalstatefaU tomeetASTM Standard C-33. In an effort to classify these materials as to which may be best for upgrading to fine or coarse aggregate, Friddell (1987, p. 15) deviSed a value system. Values assigned to each sample are based on whether the sample meets one or more of Frlddell's sieve analysis requirements (seeTable 1). Each ofFrlddell's requirements has a value of one; so the rating of a particular sample can vazy from 0 to 3. These rating values are listed 1n the table for each county. COUNTY REPORTS Atkinson County Geology and Physiography The surficial sediments of Atkinson County are derived from theAltamahaFormatlon. Atkinson County lies within the Bacon Terraces and the Tifton Upland Districts of the Coastal Plain Province. Previous Study Teas (1921. p. 153) described mediumgrained sand hJlls along the banks of Seventeenmile Creek (Fig.5, Ts-1) and the Satilla River(Ftg.5, Ts-2). The upper portion ofthis sand is said to be suitable for mortar sand. Present Study The soil association used ln targeting areas for sampling in Atkinson County was #24 (see p. 7) which is present as sand hllls along the Alapaha and Satilla Rivers and Seventeenmile Creek. The geomorphic features used 1n targeting were the large sand hllls present along the Alapaha and Satllla Rivers and Seventeenmile Creek. The preferred soil type, geomorphic features, and the favorable areas described byTeas overlap each other in Atkinson County. Three sttes were sampled in Atkinson County (Fig.5, Table 2.). Evaluation Sample Atk-1 was taken from a deposit of sandy soil; sample Atk-2 was taken from the sand dunes along the Satllla River. Sample Atk-3 was taken from an area of sandy soil and sand hllls along the Alapaha River. Although the site represented by sample Atk-3 contained some coarse material, none of the samples tested met AS1M Standard C-33. 10 --- --, 8 t ' s 1'09 ' ' EXPLANATION Sample locality III Teas' sample locality 9 Geomorphic feature R Sandy soil type -------- N 0 5 Miles t R R R 0 5 Kilometers HHR Refer to Plate 1 for overall construction material potential of this county.

Ben Hlll County lies entirely Within the Coastal Plain Province and is representedbytheVidalia Upland, BaconTerraces, and Tifton Upland Districts. Previous Study Teas (1921, p. 156) reported an apparent terrace deposit consisting of coarse sand three mlles northwest of Fitzgerald (Fig.13, Ts-3). This sand had been mined previous to Teas' time, and at the time of Teas' report was being used locally for concrete sand. Teas (1921, p. 157) also noted the presence ofa large sand belt lhat extends along the AlapahaR1verthroughoutwestemBen Hlll County, (F1g.l3. Ts-4); and he, particularly, noted the extensiveness ofthe belt near Rebecca (Flg.13, Ts-5). Teas (1921, p. 157) also noted the presence of coarse sand in the Ocmulgee River bed. Present Study The soil associations used in targeting areas for sampling in Ben Hill County were Alapaha, Fuquay. Kershaw, and Troup. These are present throughout the county as sand hills and terrace deposits. The geomorphic features targeted are possible terraces and sandbars associatedwith the Ocmulgee River and sand hills along the Alapaha River. Four sites were sampled in Ben Hill County (Fig.13, Table 4). Evaluation None of the samples analyz.ed met .AS1M StandardC-33. SampleBeH-1 was takenfromafavorable soil body, but proved to be too fine-grained for use as construction aggregate. Samples BeH-2, BeH-3a, BeH-3b and BeH-4 were taken from favorable sites noted by Teas (F1g.13, Ts-4, Ts-5, and Ts-3, respectively). These are too well-sorted and too fine-grained for use as construction aggregate. Mining Activity There is no active or recently inactive mining activity in Ben Hill County. Summary Evaluation There were no sites found that could provide construction aggregate in Ben Hill County. The constructionmaterial potential for Ben Hill County is considered to be low. Table 4.

BerrienCounty lies entirely within the Tifton Upland District of the Coastal Plain Province. Previous Study Teas (1921, p. 157) noted the presence offairly coarse-grained sand overlain by fine-grained sand near Nashville (Fig.19, Ts-6). This sand was used locally at the time of Teas' report. East of the Alapaha River, within the sand belt, there is a particular occurrence of coarse sand noted by Teas (Fig.19, Ts-7). Present Study The soU series used itl targeting s!tes in BerrienCountywereFuquay,MascotteandRutlege. These soU types are present as terraces and sand dunes along the Alapaha, New, and WUlacoochee Rivers. The geomorphic features targeted were sand dunes along the Alapaha and New Rivers, and correspond to the preferred soU types. Five sites were sampled in Berrien County (Fig.19, Table 5). Evaluation Ber-1 was taken from a sand dune along the Alapaha River. Ber-2 and Ber-4 were taken from a preferred soU type. Sample Ber-3 was taken from a site of the preferred soU type, and near a locality noted by Teas (1921). Sample Ber-5 was taken from a preferred soU type, and a possible terrace deposit. None of the samples analyzed met ASTM Standard C-33. Mining Activity There are no active or recentlyinactive IIlin1ng operations in Berrien County. Summary Evaluation All the sites represented by samples in Berrien County apparently contain sand that is too finegrained for use as construction aggregate: therefore, the construction material potential for Berrien County is considered to be low.

Geology and Physiography The surficial sediments of Bibb County are derived from the crystalline rocks ofthe Piedmont, the Oconee Group, and Quaternary alluvium. The part of Bibb County that is within the study area lies within the Fall Line Hills District ofthe Coastal Plain Province. Previous Study Teas (1921, p. 159) reported that the Macon Sand and Supply Company had a sand operation onthewestbank oftheOcmulgeeR1ver(Fig.25, Ts8) and shipped the sand at least as far as Atlanta. Finer-grained sand is reported east of this site (Teas, 1921, p. 160; Fig.25, Ts-9). Present Study The soil series used in targeting sites for sampling was Lakeland. The geomorphic features present are possible terrace deposits near the Ocmulgee River. Five samples representing four sites were analyzed from Bibb County (F1g.25, Table 6). Evaluation Samples Bib-1a, Bib-1b, and Bib-4were taken near the sites of aggregate quarries operated by Williams Brothers (Fig.25, A-024 and A-023, respectively). Neither of these samples met ASTM StandardC-33. Bib-1 was toowell-sortedandBib4 was too fine-grained for use as construction aggregate in its natural state. However, samples Bib-2 and Bib-3 represent an abandoned sand pit; and they both met ASTM Standard C-33. Mining Activity Williams Brothers operates three aggregate pits in Bibb County (Fig.25, A-022, A-023, A-024) but would not reveal any information concerning their operation. All that is lmown is that there are active construction aggregate pits in Bibb County. Table 6. Bibb County Sample Data Sample designation Depth!

Theirproxtmityto existing sand operations roughly defines the extent of these existing pits. The most favorable area for new aggregate potential in Bibb County is represented by samples Bib-2 and Bib3. The deposit sampled occurs over an area of approximately 10 acres and to a depth of at least 25.5 feet; this deposit could yield 555,000 tons of material. The construction material potential in this part of Bibb County is considered to be moderate. Bleckley County Geology and Physiography The surficial sediments of Bleckley County are derivedfrom the Barnwell Group, theAltamaha Formation. and deposits ofOligocene age. Bleckley County lies within the Fall Line Hills and Vidalia Upland Districts of the Coastal Plain Province. Previous Study Teas (1921) reported no significant amount of suitable sand in Bleckley County. Present Study The soil associationtargeted inBleckleyCounty was #24 (seep. 7), which is present as isolated areas remotely associated with the Ocmulgee River. There were no apparent geomorphic features indicative ofsand or gravel deposits. Three samples, representing two sites, were analyzed for aggregate potential (Fig.31; Table 7). Evaluation Samples Ble-2a and Ble-2b represent the preferred soil type. The material failed to meet ASTM Standard C-33 and is too well-sorted for use as construction aggregate. Sample Ble-1 represents a four foot exposure of clayey sand with occasional pebbles. This site extends for approximately 20 acres and to a depth of four feet. This clayey sand deposit could produce as much as 174,000 tons before upgrading. Although this Table 7.

Coffee County lies entirelywithin the Coastal Plain Province, with the greater portion of Coffee County lying within the Bacon Terraces District, and the remainder being situated in the Vidalia Upland and Tifton Upland Districts. Previous Study A large sand belt along Seventeenmile Creek was reported byTeas, (1921, p. 178; Fig.40, Ts-11). He also noted a small sand pit (p. 178; Fig.40, Ts12) that has been worked intermittently, with the sand being used for local paving, as well as foundry use. More sand of this type was reported by Teas (1921) along the railroad north of Douglas (p. 179; Fig.40, Ts-13). Teas also reported the presence of coarse sand bars in the Ocmulgee River. Present Study The soil association used in targeting sites in Coffee County was #24 (see p. 7). which corresponds to the geomorphic features targeted; the large sand hills along the banks ofthe Satilla River and Seventeenmile River. Four sites were sampled and analyzed for aggregate (Fig.40; Table 9). Evaluation The area from which samples Cof-1 and Cof4 were taken represents the favorable soil type, the targeted geomorphic feature, and was an area mentioned by Teas (1921, p. 178-179). The material present at these sites failed to meetASI'M Standard C-33. The sediments are too fine-grained and too well-sorted for use as construction aggre- gate. Samples Cof-2, and Cof-3 marginally failed ASTM Standard C-33, but could be upgraded. These two sampleswere taken from areassimilarto the sites for Cof-1 and Cof-4, but may be suitable for construction aggregate, if upgraded. Mining Activity There are no active or recently inactive mining operations in Coffee County. Summary Evaluation The deposits represented by Cof-2 and Cof-3 could be sources of construction aggregate. Cof-2 represents a site of about 20 acres, and approximately 12 feet in thickness. Reserves could prove to yield 500,000 tons, before upgrading. The site represented by Cof-3 encompasses approximately 200 acres, with a thickness of approximately 16 feet; reserves could yield 6,000,000 tons, before upgrading. The construction material potential of Coffee County is considered to be moderate. Table 9.

CI1sp County lies within the TiftonUpland District ofthe Coastal Plain Province. Previous Study Teasreportedno suitable amount orqualityof sand for commercial use in Crtsp County. Present Study The soil sertes used for targeting sampling sites in CI1sp County was Lakeland, which is present as isolated pods. There were no apparent geomorphic features indicative of sand or gravel deposits in CI1sp County, and only one site was sampled for analysis (Fig.48, Table 11). Evaluation Sample CI1-1 was taken from a preferred soil body. The matertal is too fine-grained to meet ASTM Standard C-33. Mining Activity There are no active or recently inactive mining operations 1n CI1sp County. Summary Evaluation The sample containing the coarsest grained sand is too fine-grained for use as construction aggregate. The construction aggregate potential for this part of Crisp County is considered to be low. Doda;e Countv Geology and Physiography The surficial sediments ofDodge County are dertved from theAltamaha Formation and deposits ofOligocene age. Dodge County lies entirelywithin the Vidalia Uplands District of the Coastal Plain Province. Previous Study Teas (1921, p. 189) reported fine-grained sand near Eastman (Fig. 50, Ts-14) suitable for building purposes. He also reported that medium- to coarsegrained sand is found on sand bars throughout the OcmulgeeRiver(Teas, 1921, p. 189; Fig.50, Ts-15). Teas (1921, p. 189-190) reported an occurrence of gravel with pebbles up to two inches in diameter northwest of Eastman (Fig. 50, Ts-16). This gravel had been used for building and roads. A thin gravelly deposit two miles long, near Gresston, (Fig.50, Ts-17) was reported byTeas (1921, p. 190).

Five samples representing four sites were analyzed for aggregate potential (Ffg.50, Table 12). Evaluation The site for sample Dod-1 was a preferred soil type and was mentioned by Teas (1921, p.189). Samples Dod-4a and 4b were taken from a preferred soil type. None of these samples met ASTM Standard C-33; however, Dod-4a represents the upper 8 feet ofa 30 acre site and could be upgraded to meetstandards. Samples Dod-2 and Dod-3 were also taken from preferred soil types. Dod-2 marginally failed to meet ASTM Standard C-33, but could be upgraded: and Dod-3 represents a one-foot thick gravelly layer, which could provide a small amount of fine- and coarse-grained aggregate. Mining Activity There are no active or recently inactive mining operations in Dodge County. Swnmary Evaluation The site representedbyDod-3 containscoarse material, but the site is too small to be ofeconomic value. Overall, the construction material potential for Dodge County is considered to be low to moderate.

Summary Evaluation Therewere no favorable areas in DoolyCounty from which to select a site for sampling, therefore, no analyses were done. The construction mate11al potential for Dooly County is considered to be low. Echols County Geology and Physiography The surficial sediments of Echols County are composed of the Hawthorne Group and the Miccosukee Formation. Echols County lies within the Tifton Upland and the Okefenokee Basin Districts of the Coastal Plain Province. Previous Study Teas (1921, p. 195-196) noted the presence of large sand dunes at Statenville (Fig.56, Ts-18). These dunes are composed of 2 to 3 feet of coarsegrained sand overlain by8 feet offine-grained sand. Present Study The soil association used in targeting sites for sampling in Echols Countywas #24 (seep. 7) which is present along the Alapaha River. This overlaps the large sand hills along the Alapaha River, targeted as geomorphic features. Five samples rep- Table 13.

Evaluation Sample Ech-1 represents a site within a favorable geomorphic feature. Sample Ech-4 represents a site within a favorable soil body and geomorphic feature. Sample Ech-2a represents the upper sixteen feet of a twenty foot sample from a site within a favorable soil type. These samples are too wellsorted for use as construction aggregate, and failed ASTM Standard C-33. However. sam.Ple Ech-2b, which represents the lowerfour feet ofsample Ech2a, is comprised of coarse-grained sand and marginally failed ASTM Standard C-33. Sample Ech3 represents a site within a favorable soil body. and marginally failed ASTM Standard C-33, and can be upgraded. Mining Activity There is one active aggregate operation in Echols County. Rountree Construction operates a two acre pit in a forty acre tract. They mine approximately 10.000 tons per year by way of backhoe and dredge. This material is transported by truck to the Valdosta and Lowndes County areas. Summary Evaluation The site represented by samples Ech-2a and Ech-2b could be exploited for construction mate- rial, but the sixteen feet ofoverburden represented by sample Ech-2a would probably make this stte unprofitable. The 5 acre. 12-foot thick deposit represented by sample Ech-3 could be a source of aggregate. This deposit could provide as much as 129,000 tons of material, before upgrading. Considering these two sites, and the presence of an active aggregate operation, the construction material potential for Echols County is considered to be moderate to high. Hancock Countv Geology and Physiography The surficial sediments of Hancock County are derived from the crystalline rocks of the Piedmont Province and the Barnwell Formation. Most of Hancock County lies outside the study area in the Piedmont Province, but the southern section of the county lies within the Fall Line Hills District of the Coastal Plain Province. Previous Study Teas (1921, p. 203) reported sand and pebble layers within clay near Carr's Station in Hancock County (Fig.62, Ts-19).

The geomorphic feature noted was a possible terrace nearTown Creek. Four sites were sampled for analysis of construction aggregate in Hancock County (Fig.62, Table 14). Evaluation Sample Han-4 represents a preferred soil type. This sample failed to meetASTM Standard C33: the material is too fine-grained for use as construction aggregate. Sample Han-1 was taken at a favorable soU body: and at a locality mentioned by Teas (1921, Fig.62, Ts-44). Sample Han-2 was taken from a preferred soU type. Sample Han-3 was taken from a site that was an abandoned pit, and also, is a favorable soU type. These samples all contain coarse-grained material. All four samples marginally failed ASTM Standard C-33 but could be upgraded. Mining Activity With the exception of one abandoned pit for which no information is available, there are no active or recently inactive aggregate operations in Hancock County. Summary Evaluation The site represented by sample Han-1 is 5 acres in extent, approximately 8 feet thick, and contains coarse-grained material. Sample Han-2 represents a 5 acre site, wtth coarse-grained sand and gravel at least 4 feet in thickness. Sample Han3 represents a 10 acre, abandoned sand pit. The deposit extended to a depth of 8 feet. These three sites could be sources for construction aggregate in Hancock County, possibly providing 87,000 tons: 42,000 tons: and 174,000 tons of material, respectively, before upgrading. The construction material potential for Hancock County is considered to be moderate to high.

Although a small pit had been worked at that site, Teas reported that the sand is too finegrained and not suitable for construction purposes. Present Study The soil series used in targeting sites in Houston County was Lakeland, which is present near various streams throughout Houston County. The geomorphic features noted were sand hills along Indian Creek. Six siteswere sampled and analyzed for construction aggregate in Houston County (Fig.67, Table 15). Evaluation Samples Hou-1, Hou-3, and Hou-5were taken from a preferred soil type and targeted geomorphic feature. These samples did not meet ASTM Standard C-33, as thematertalts too well-sorted. Sample Hou-4 was taken from the preferred soil type, and Hou-6 was taken from what appeared to be a favorable site from field observation. Both of these samples proved to be too fine-grained for construction aggregate. The site from which sample Hou-2 was taken was a 12-foot high sand dune. This site is a preferred soil type and a targeted geomorphic feature. Near this site is an abandoned sand pit for which no information is available. The material in this sample marginally failedASTM Standard C-33 and could be upgraded. Mining Activity There are two mining operations in Houston County (Fig.67, F-807, F-578). Both are operated by the county and produce only fill material for use in road building. Summary Evaluation The site represented by sample Hou-2 offers the best possibility for aggregate production in Houston County. The material marg1nally failed ASTM Standard C-33 but could be upgraded. The construction material potential for this part of Houston County is considered to be moderate. Irwin County Geology and Physiography The surficial sediments of Irwin County are derivedfrom theAltamaha Formation. hwinCounty, which is completely within the Coastal Plain Province, lies almost entirely within the Tifton Upland and Bacon Terraces Districts, with a small portion being in the Vidalia Upland District. Previous Study Teas (1921, p. 205-206) reported large sand hills along the Alapaha River which may have conunercial value (Fig.74, Ts-21). Table 16.

These soU types are present along the vartous rivers and creeks of the county, and roughly correspond to some ofthe geomorphic features. The geomorphic features noted were the sand hills present along the Alapaha River. Four sites were sampled and analyzed for construction aggregate in Irwin County (FJg.74, Table 16). Evaluation Sample lrw-1is from a preferred soU type. The sample did not meet ASTM Standard C-33 and is too fine-grained for use as construction aggregate. Sample lrw-2 was also taken from a preferred soil type. This sample marginally faUed ASTM Standard C-33 but could be upgraded. Samples Irw-3 and lrw-4 were taken from the preferred soil type andthe site oftargetedgeomorphicfeatures. Sample lrw-3 was taken from an area near the site of an abandoned sand pit. These samples marginally failed ASTM Standard C-33. Mining Activity Other than an abandoned sand pit, forwhlch no information is available, there are no active or recently inactive aggregate operations 1n Irwin County. Summary Evaluation Three samples from Irwin County (Irw-2, lrw3, and Irw-4) marginally failed ASTM C-33 and could provide construction aggregate, with upgrading. The construction material potential for Irwin County is low to moderate. Jeff Davis CountY Geology and Physiography The surficial sediments of Jeff Davis County are derived from the Altamaha Formation and Quaternary alluvium. Jeff Davis County lies within the Vidalia Upland and Bacon Terraces Districts of the Coastal Plain Province. Previous Study Teas (1921, p. 206) reported that coarse sand is present in a terrace deposit ofthe Ocmulgee River near Lumber City (Fig. 79, Ts-22) and 1n sand bars throughout the course of the Ocmu1gee River.

Size distribution curve of Sample JeD-6. *Unified Soil Classification System **Wentworth-Lane Class Limits sampling in Jeff Davis County were Kershaw and Mascotte, which are present as isolated areas throughout the county. The geomorphic features noted were the sand hills along Hurricane Creek. Six sites were sampled and analyzed for construction aggregate in Jeff Davis County (Fig. 79, Table 17). Evaluation Sample J eD-2 was taken from a preferred soil body and geomorphic feature. The material is too fine-grained for use as construction aggregate and does not meet ASTM Standard C-33. Sample JeD1was taken from a preferred soil type and near the site ofan abandoned sand pit for which no information is available. Sample JeD-6 was taken from a preferred soil type and, also, the site of a targeted geomorphic feature. These samples marginally failed ASTM Standard C-33 and could be upgraded. The remaining three samples, JeD-3, JeD-4, andJeD-5, are from point bars along the Ocmulgee River. SamplesJeD-3 andJeD-4marginallyfailed ASTM Standard C-33 but could be upgraded. Sample JeD-5 meets ASTM Standard C-33. Depending on the water level, these point bars in the Ocmulgee River canvaryfrom approximately five to ten acres in size and could provide from 20,000 to 40,000 tons of material. Mining Activity Other than an abandoned pit, for which there is no information available (Fig. 79). there are no active or recently inactive mining operations in Jeff Davis County. Summary Evaluation The point bars along the Ocmulgee River offer the best possibility for aggregate production in Jeff Davis County. But due to theirlimited areal extent, min1ng may not be profitable. The construction material potential for Jeff Davis County is considered to be moderate. Johnson County Geology and Physiography The surficial sediments of Johnson County are derived primarily from the Altamaha Group with minor deposits of the Barnwell Group and Quaternary alluvium. Johnson County lies in the Coastal Plain Province and almost entirely within the Vidalia Upland District. A small portion of the county lies in the Fall Line Hills District. Previous Study Teas (1921, p. 209) reported that the sand belt along the Little Ohoopee River (Fig.86, Ts-23) consisted of fine-to medium-grained sand and was at that time being used as traction sand. Teas (1921, p. 209) reported a 5-acre gravel deposit, about 2 feetthick(Fig. 86, Ts-24), belongingto J.H. Rowland, located about 5 miles from Wrightsville. Teas (1921) also reported a 20-acre deposit ofgravel and concrete sand near Donovan (Teas, 1921, p. 209210: Flg.86, Ts-25). Gravel was reported by Teas (1921, p. 21 0) at the McCrary property, 6 miles northwest of Wrightsville, (Fig.86, Ts-26): the Brantley property, 3 milesfromWrlghtsv1lle, (Flg.86, Ts-27): the Smith property, 2 miles from Adrian (Fig.86, Ts-28): the Flanders property, 1.5 miles from Adrian, (Fig.86, Ts-29): and an occurrence of clayey gravel at Neels Creek (Fig.86, Ts-30). Present Study The soil association used in targeting sites in JohnsonCountywas#39 (seep. 7), which overlaps the geomorphic features noted, sand hills along the Little Ohoopee River. Six samples representing five sites were analyzed for construction aggregate (Fig.86, Table 18). Evaluation Sample Joh-2 is from the preferred soil type and a targeted geomorphic feature. Samples Joh1, Joh-3 and Joh-5 are from sites noted by Teas (1921: Fig. 86, Ts-28, Ts-25, and Ts-24, respectively). Samples Joh-4a and Joh-4b are from a site noted by Teas (1921, Fig.86, Ts-23), which is also a location of the preferred soil type, and a targeted geomorphic feature. None of the samples analyzed met ASTM Standard C-33. All samples, with the exception of Joh-4a, were too fine-grained for use as construction aggregate. Although there is some coarsegrained material present in sample J oh-1, there is too much fine-grained material, and the deposit is too small to be considered. Sample Joh-4a is too well-sorted and marginally failed ASTM Standard C-33 but could be upgraded. This sample represents a fifteen-acre site with possible reserves of 500,000 tons, before upgrading. 108 82"43'12" N t """- .

Mining Activity There are no active or recently inactive aggregate operations in Johnson County. Summary Evaluation Sample Joh-4a could be suitable for construction aggregate use: however, the supplywould be l1mited. Construction material potential for Johnson County is considered to be low. Jones County Geology and Physiography The surficial sediments of Jones County are derived from the crystalline rocks of the Piedmont Province, the Barnwell Group, and the Oconee Group. Most of Jones County lies within the Piedmont Province and outside the study area: however, the southern portion lies within the Fall Line HUls District of the Coastal Plain Province. Previous Study Teas (1921) made no mention of occurrences of sand or gravel in the Coastal Plain of Jones County. Present Study The soil series used in targeting sites in Jones County was Lakeland, which is present sporadically throughout the county. There were no geomorphic features apparent that are indicative of sand orgravel deposits. Two sampleswere analyzed for construction aggregate in Jones County (Fig.93, Table 19). Evaluation Both samples were taken from preferred soil types. Jon-1 was too fine-grained for use as construction aggregate, and failedASTM Standard C-33. Jon-2 marginally failed ASTM Standard C33 but could be upgraded. Mining Activity There are no active or recently inactive aggregate operations in Jones County.

Lanier County lies within the Coastal Plain Province and almost entirely within the Tifton Upland District with a small portion being in the Okefenokee Basin. Previous Study Teas made no mention of sand or gravel deposits in Lanier County. Present Study The soil series used in targeting sites for samplinginLanierCounty were Fuquay, Mascotte, and Rutlege. This is present at higher elevations near streams. The geomorphic features targeted were the sand hills along the Alapaha River. 1\vo sites were sampled for construction aggregate in Lanier County (Fig.96, Table 20). Evaluation Sample Lan-1 was taken from a targeted geo~orphic feature. This sample failed to meet ASTM Standard C-33, because the material is too fine-grained. Sample Lan-2 was taken from a preferred soil type. This sample was too well-sorted to meet ASTM Standard C-33. Mining Activity There are no active or recently inactive aggregate operations in Lanier County.

Laurens County Geology and Physiography The surficial sediments of Laurens County are derived from the Altamaha Formation, the BarnwellGroup, and Quaternaryalluvium. Laurens County lies within the Vidalia Upland and Fall Line Hills Districts of the Coastal Plain Province. Previous Study Teas (1921, p. 211) noted an extensive occurrence of sand at what is now East Dublin (Fig.99, Ts-31). Sand was being mined from this locality during the time of his study. Also noted was the occurrence of coarse sand in the flood plain and sand bars of the Oconee River (Teas. 1921, p. 212). Teas (1921, p. 213) reported a gravel deposit on the Carter property (Fig.99, Ts-32) that covers 3000 acres and is 2 to 5 feet thick. Present Study The soil association used in targeting sites for sampling in Laurens County was #24 (see p. 7) and is present as a floodplain deposit east of the Oconee River. Geomorphic features noted were the sand hills and sand bars present along the Oconee River. Five sites in Laurens County were sampled and analyzed for construction aggregate potential (Fig.99, Table 21). Evaluation Sample Lau-1 was taken from a preferred soil type. Analysis shows that the material is too wellsorted and too fme-grained for use as construction aggregate. Sample Lau-5 was also taken from a preferred soil type. Sample Lau-4 was taken from an occurrence ofsand reported in the unpublished files at the Geologic Survey. Although neither Lau4 or Lau-5 met ASTM Standard C-33, the material could be upgraded for use as construction aggregate. Samples Lau-2 and Lau-3 were taken at the site of a sand pit operated by Holmes Co. (Fig.99, 1156), which also is a site noted by Teas (1921). Sample Lau-2 is representative of the entire site. Sample Lau-3 represents a thin, continuous gravel layer. Both of these samples marginally failed ASTM Standard C-33 and could be upgraded. This material has been used in the recent past for aggregate. Mining Activity Holmes Sand and Gravel Co. recently operated a pit at East Dublin, (Fig.99, I-156) but no infommtion is available about their operation. C.M.G. Co. (Fig.99, F-489) operated a pit for producing fill material. but no other information is available. Table 21.

Montgomery County lies within the Vidalia Upland District of the Coastal Plain Province. Previous Study Teas (1921, p. 221) mentioned that coarse sand is present in the Oconee River bed. Present Study The soil series used in selecting sites for sampling in Montgomery County were Kershaw and Paola, and occur sparsely as isolated bodies. The geomorphic features sited were sand hills and sand bars along the Oconee River. Four samples representing three sites in Montgomery County were analyzed (Ffg.llO, Table 23). Evaluation Sample Mon-3 was taken from a targeted geomorphic feature. The material is too fine-grained and too well-sorted for use as construction aggregate. Samples Mon-1a and Mon-1b were taken from the proximity of a sand pit referenced in Georgia Geologic Surveyfiles. The upper four feet of this sample (Mon-1a) marg1nally failed to meet ASTM Standard C-33 but could be upgraded. The lower four feet ofthe sample (Mon-1b) also failed to meetASTM StandardC-33; thematerialistooflnegrained. Sample Mon-2 was taken from a preferred soil type; the material marginally failed ASIM Standard C-33 but could be upgraded. Mining Activity Montgomery Sand Company, a division of Florida Crushed Stone Co. (Ffg.110, A-355), operates a 60 acre pit from a 420-acre tract ofland near Mount Vernon and the Oconee River. Mining is done by a suction dredge. Concrete, mortar, trap (for golf course use), and sandblasting sand, in addition to well gravel, is transported bytruckfrom the pit to within a 250-mile radius. Swnmary Evaluation The site represented by sample Mon-2 is a 40 acre tract: the sampled material extends 13 feet in depth. Sample Mon-1a represents a twenty acre tract and extends four feet in depth. Although the material analyzed marginally failed ASTM Standard C-33, both these sites could provide limited amounts of construction aggregate. There is, however, construction aggregate being mined at the Montgome:ry Sand Company. The construction material potential for Montgomery County is considered to be moderate. Table 23.

Geology and Physiography The surficial sediments of Peach County are derived from the Barnwell Group, the Oconee Group and the Marshallville Formation. Peach County lies within the Fall Line Hills and the Fort Valley Plateau Districts of the Coastal Plain Province. Previous Study Teas made no mention of sand occurrences in Peach County. Present Study The soil series used in targeting sites in Peach County was Lakeland and occurs as isolated bodies near streams. A possible terrace deposit of the Echeconnee Creek is the geomorphic feature targeted. It overlaps a targeted soil body. One site in Peach County was analyzed for construction aggregate (Fig.115, Table 24). Evaluation Sample Pch-1 is from a preferred soil body, whichcorrespondsto a targetedgeomorphic feature, and is inthe vicinity ofan inactive sand pit (Fig. 115, 1-525). The matenalis too fine-grained, and too well-sorted for use as construction aggregate. Mining Activity At one time Southern Aggregate of Augusta operated a sand pit in Peach County (F1g.115, 1525), but it has since been reclaimed and no other information is available. Swnmary Evaluation The site sampled in Peach County evidently would not be a good source for construction material, and there is no m1n1ng activity. Therefore, the construction material potential for this part of Peach County is considered to be low. Pulaski County Geology and Physiography The surficial sediments ofPulaski County are derived from deposits ofOligocene age and Quaternary alluvium. This countylieswithin the Fall Line Hills and Vidalia Upland Districts of the Coastal Plain Province. Previous Study Teas (1921, p. 229-230) noted that the sand bars in the Ocmulgee River were possible sources of aggregate. Present Study The soil association used in targeting sites for sampling in Pulaski County was #39 (see p. 7). and is found along the Ocmulgee River, roughly corresponding to the targeted geomorphic features. The geomorphic features noted were the sand hills. ten-aces. and sand bars along the Ocmulgee River. Five siteswere sampled, and analyzedfor construction aggregate potential (Fig.11 7, Table 25).

Samples Pul-3 and Pul-4 were taken from the sand hills along the Ocmulgee River. Sample Pul-5 was taken from a sand bar on the Ocmulgee River. None of the material analyzed met ASTM Standard C-33. Samples Pul-l, Pul-2, and Pul-4 are too finegrained, and samples Pul-3 and Pul-5 are too wellsorted for use as construction aggregate. Mining Activity There are no active or recently inactive aggregate operations in Pulaski County. Summary Evaluation Although the material in sample Pul-2 is too fine-grained, it could be upgraded. This site is a 50 acre tract. If mined to a depth of 15 feet, this site could produce reserves up to 545,000 tons, before upgrading. There are several sand bars along the Ocmulgee River that could also provide some construction aggregate. The sand bar sampled (Pul-5) extends for approximately 20 acres and to a depth of approximately 2 feet. The construction material potential for Pulaski County is moderate to high. Telfair County Geology and Physiography The surficial sediments ofTelfair County are derived from the Altamaha Formation and Quaternary alluvium. Telfair County Ues within the Vidalla Upland District of the Coastal Plain Province. Previous Study Teas (1921, p. 257) reported a small pit near Lumber City, (Fig.l23, Ts-33) that produced good quality concrete sand. Teas (1921, p. 258) also mentioned a deposit of medium-grained sand at Sugar Creek (FJg.l23, Ts-34) and again mentioned the presence of good quallty sand in sand bars along the Ocmulgee River (1921, p. 258). Present Study The soU association #39 (see p. 7) was used in targeting sites for sampling inTelfair County and generally corresponds to the sand hills along the Ocmulgee River. The geomorphic features targeted are the sandhills and sandbars alongthe OcmuJgee River. Five samples representing four sites in Telfair County were analyzed for aggregate potential (Table 26).

Samples Tel-2a and Tel-2b were taken from the preferred soil type. Samples Tel-3 and Tel-4 were taken from the sand hills along the Ocmulgee River where they correspond to a preferred soil type. None of the samples met ASTM Standard C-33. Tel-l and Tel-2b are too fine-grained: Tel-3 andTel4 are both too fine-grained as well as too well-sorted for use as construction aggregate. However, Tel-2a marginally failed, it could be upgraded. Mining Activity There are no active or recently inactive mining operations in Telfair County. Teas (1921, p.257) mentioned a small pit in the county, and there is another abandoned pit for which no information is available. Swnmary Evaluation Sample Tel-2a represents a 10-foot thick deposit of coarse-grained sand and gravels that extends for approximately 10 acres. This site is in the vicinity ofan abandoned pit. Overall, the construction material potential for Telfair County is considered to be low. Tift County Note: A description ofthe aggregate potential for that part of Tift County which lies west of 1-75 may be found in Construction Material Potential of the Coastal Plain of Southwestern Geomia: An Evaluation, Georgia Geologic Survey Bulletin 106; (Friddell, 1987, p. 230-238). Geology and Physiography The surficial sediments of Tift County are derived from the Altamaha Formation. Tift County lies within the Tifton Upland District ofthe Coastal Plain Province. Previous Study Teas made no mention ofsand deposits inTift County. Present Study The soil series used in targeting sites for sampling in Tift County were Lakeland and Mascotte. There were no apparent geomorphic features indicative ofsand orgravel deposits present in Tift County. Three samples representing two sites were analyzed from Tift County for construction aggregate potential (Fig.l29, Table 27). Evaluation Samples Tif-1, Tif-2a and Tif-2b were taken from areas of preferred soil types. None of the samples metASTM Standard C-33. All are too wellsorted for use as construction aggregate.

Summary Evaluation None of the areas targeted in Tift County are potential sites for aggregate production. The materials present are too well-sorted. The construction material potential for this part of Tift County is considered to be low. Treutlen Countv Geology and Physiography The surllcial sediments of Treutlen County are derived from the Altamaha Formation and Quaternary alluvium. Treutlen County lies within the Vidalia Upland District of the Coastal Plain Province. Previous Study Teas (1921, p. 264) mentionedseveralsmallsand deposits in Treutlen County. A small pit north of Soperton (Flg.l33, Ts-35) provided sand for local use. Near Red Bluff Creek (Flg.l33, Ts-36) there is an occurrence offine-grained sand. Medium- to coarsegrained sand is present in the Oconee River bed. Present Study The soU series used in targeting sites for sampling in Treutlen County was Lakeland and is found at various places along Pendleton Creek and the Oconee River. The geomorphic features noted were the sand hills at Pendleton Creek. and near the Oconee River. Seven samples representing six sites were analyzed for aggregate potential from Treutlen County (Table 28). Evaluation SamplesTre-la, Tre-lb andTre-2 were taken from areas of the preferred soU type that correspond to targeted geomorphic features. Samples Tre-3 and Tre-4 were taken from sand bars along the Oconee River. Samples Tre-5 and Tre-6 were taken from areas noted by Teas (1921, p.264). None of the samples analyzed met ASTM Standard C-33. Samples Tre-la, Tre-3, and Tre-4 were too well-sorted. Samples Tre-1b, Tre-2, Tre5, and Tre-6 were too fine-grained for use as construction aggregate. Mining Activity Other than the small pits mentioned by Teas (1921, p. 264), there are no known active or inactive mining operations in Treutlen County. Table 27.

Summary Evaluation None of the samples analyzed for aggregate potentialmetASTM Standard C-33, and there is no evidence to support the potential for aggregate production in this county. The construction material potential for Treutlen County is considered to be low. Turner County Note: A description ofthe aggregate potential for that part ofTurner County which lies west ofl75 maybefound inConstruction Material Potential of the Coastal Plain of Southwestern Geor~ta: An Evaluation, Georgia Geologic SuiVey Bulletin 106: (Friddell, 1987, p. 239-242). Geology and Physiography The surficial sediments ofTurner County are derived from the Altamaha Formation. Turner County lies within the Tifton Upland District ofthe Coastal Plain Province. Previous Study Teas (1921, p. 265) reported one small deposit ofmedium-grained sand at Deep Creek in Turner County (Fig.l41, Ts-37). Present Study The soil series used in targeting sites for sampling in Turner County were Kershaw and Lakeland, which are present as isolated bodies near Wolf, Deep and Lake Creeks. There were no apparent geomorphic features indicative ofsand or gravel deposits. Four sites were sampled, and the material analyzed for aggregate potential (Table 29). Evaluation Samples Trn-1, Trn-3 and Trn-4 were taken from areas ofpreferred soil types: sampleTrn-2 was taken from a preferred soil type that corresponds to a locality mentioned byTeas (1921, p.265). None of the samples metASTM Standard C-33. Trn-3 ~too fine-grained for use as construction aggregate. Samples Trn-1, Trn-2, and Trn-4 are too wellsorted, but containvery little fine-grained material. These three samples could be upgraded to meet ASTM Standard C-33. Mining Activity Prior to 1985, Reeves Construction Company was mining a 20-acre pit for fill material in Turner County (Fig.l41, I-691).

Ware County Geology and Physiography The surficial sediments of Ware County are derived from the Altamaha Formation: as well as the Statenville and the Cypresshead Formations of the Hawthorne Group. Ware County lies within the BaconTerraces and the Okefenokee BasinDistricts of the Coastal Plain Province. Previous Study Teas (1921, p. 266) mentioned the occurrence ofmedium-to coarse-grained sand along the Satilla River (Ftg.153,Ts-40): and particularlyat the railroad crossing (Ftg.153, Ts-42). Teas (1921, p. 266) reported that clean medium-grained sand is present in large quantities on the banks of the Satilla River (Ftg.153, Ts-43) and along the banks of Seventeenmile and Hog Creeks (Fig.153, Ts-41). Present Study The soil association targeted for sampling sites in Ware County was #24 (see p. 7). This overlaps the geomorphic features noted which are the sand hills along the SaUlla River and Seventeenmile and Hog Creeks. Seven samples were analyzed for construction material potential in Ware County (Fig.153, Table 31). Evaluation Sample War-2 was taken from the vicinity of an abandoned sand pit that is within an area targeted for preferred soil type. Sample War-5 was taken from a targeted geomorphic feature. Sample War-6 was taken from an area ofpreferred soil type which corresponds to the sand hills along the Satilla River. Sample War-7 was taken from an area mentioned byTeas (1921, p. 266; Ftg.153, Ts42), which corresponds to a targeted geomorphic feature, and is also in the vicinity of an abandoned sand pit. None of these samples met ASTM Standard C-33. Sample War-5 is too well-sorted, and samples War-2, War-6, and War-7 are too finegrained for use as construction aggregate. Samples War-1 and War-4 were taken from areas in which a targeted soil type, targeted geomorphic features, and also a Teas locality (1921, p.266; Fig.153, Ts-40 and Ts-43, respectively) overlap. War-1 represents a 12 foot deep sample of a deposit which covers approximately 50 acres: War-4 represents a 13 foot deep sample of a tract that covers approximately 70 acres. Sample War3, taken from the vicinity of a fill-material pit (Fig.153, F-651). represents a 12 foot deep sample of a tract that extends for approximately 80 acres. Even though these samples did not meet ASTM Standard C-33, they could be upgraded for use as construction aggregate and could (before upgrad- 187 82"2 1'15" --, J', .....~ I N t EXPLANATION Sample locality lliiiii] Teas' sample locality + Active aggregate producer Inactive aggregate producer Abandoned pit, product unknown Geomorphic feature liD Sandy soil type 0 5 Miles RRR 0 5 Kilometers HE:8 Refer to Plate 1 for overall construction material potential of this county.

Mining Activity There are four active aggregate producers in Ware County (Fig.153, A-009, F-651, F-790, A825). Pit# F-651is operated by the Ware County Conunission and produces only flll material. Pit # F-790 is a 4 acre pit operated by the city ofWaycross and, also, produces flll material. Pit # A-009 is an 8 acre pit operated by Minchew Sand, and pit # A825 a 10 acre pit operated by Waycross Sand. No other information is available for any of these operations. Summary Evaluation The deposits represented by samples War-1, War-4, and War-3 could provide 430,000: 660,000: and 70,000 tons of sand, respectively, if the material were upgraded to ASTM Standard C-33. There is evidence of sand mtntng throughout the county, especially in the sand hllls along the rivers and creeks. No information was attainable from the sand producers in the county other than the fact that two producers are actively producing sand products. The construction material potential for Ware County is considered to be moderate. Washinlnon County Geology and Physiography The surficial sediments ofWashingtonCounty are derived from the Barnwell Group, the Oconee Group, and Quatemaxy alluvium. Washington County lies within the Fall Line Hills and the Vidalia Upland Districts of the Coastal Plain Province. Previous Study Teas (1921, p. 267) noted an occurrence of coarse-grained sand near Big Buffalo Creek (Fig.161, Ts-44). Present Study The soU series used in targeting sites for sampling in Washington County was Fuquay, and can be found as small sandy bodies scattered throughout the county. The geomorphic features noted were the sand hllls along the Oconee River. Four siteswere sampled and analyzed for construction aggregate in Washington County (Ftg.161, Table 32).

Sample Was-4 was taken from an area ofthe preferred son type. None of these samples met .ASIM Standard C-33. Samples Was-1 and Was-4 are too fine-grained, and samples Was-2 and Was3 are too well-sorted for use as construction aggregate. Mining Activity There is one active aggregate producer in Washington County. Anglo-American mines one acre of a 16 acre pit to a depth of 20 feet with a backhoe. The gravel undergoes no processing but is immediately transported by trucks to their kaolin pits for use as road gravel. Less than 10,000 tons is produced annually. Summary Evaluation There were no areas found in Washington County that could provide material for aggregate production. with the possible exception of the deposit being mined for road gravel by AngloAmerican. The construction material potential for Washington County is considered to be moderate to low. Wheeler County Geology and Physiography The surficial sediments of Wheeler County arederivedfrom theAltamahaFormation. Wheeler County Ues within the Vidalia Upland District of the Coastal Plain Province. Previous Study Teas (1921, p. 268-269) reported that a large deposit ofclayey sandygravel at the Darcyproperty (Fig.166, Ts-45) had been used for aggregate prior to his study. At the Little Ocmulgee River (Ffg.166, Ts-46), there are large deposits ofmedium-grained sand (Teas, 1921, p. 269). Teas (1921, p. 273) also noted a sandy gravel deposit 3.5 miles south of Glenwood (Fig.166, Ts-47) and large quantities of sand in the Oconee River (1921, p. 273). Present Study The son series used in determining sandy areas in Wheeler County were Kershaw and Paola. The targeted son bodies correspond to the geomorphic features, which are sand hills along the north and east sides of Alligator Creek. Six sites were sampled and analyzed for construction aggregate in Wheeler County (Fig.166, Table 33).

Whe-6 represents a 20-foot deep auger sample, of a site of approximately 15 acres, that could produce 500,000 tons ofmaterial. Samples Whe-4 and Whe-5 are from an area mentioned by Teas (1921, p. 269; Fig.166, Ts-46), that corresponds to preferred soil types. Whe-4 is a 10-foot auger sample, from a 10-acre deposit, that could produce 200,000 tons of material. Whe-5 is a 20foot auger sample, of a 20-acre deposit from the vicinity of a sand pit (Fig.166, A-191), that could produce 400,000 tons of material. Sample Whe-3 isfrom a small sand bar along the Oconee River and could produce 4,000 tons of material. These samples marginally failed ASTM Standard C-33 becausetheyaretoowell-sorted; however, because they contain little fine-grained material, they could be upgraded. Mining Activity There is one active producerinWheelerCounty. HollandAsphaltCompany operates 10acresofa20 acre tract (Fig.166, A-191). The operation is an open pit; they mine with a front-end loader and produce less than 10,000 tons annually for the exclusive use of Holland Asphalt. J.L. Clegg (deceased) formerly operated a sand pit (Fig.166, 1126) for which no information is available. Summary Evaluation Several of the sites sampled contain coarsegrained material and could be upgraded to provide aggregate. There is some aggregate m1n1ng taking place atthe present time. The constructionmaterial potential of Wheeler County is considered to be moderate. Wilcox Countv Geology and Physiography The surficial sediments of Wilcox County are derived from the Altamaha Formation, deposits of Oligocene age, and Quatematy alluvium. Wilcox County lies within the Vidalia Upland, Tifton Upland, and Fall Line Hills Districts of the Coastal Plain Province. Previous Study Teas (1921, p. 273) reported that only sparsely distributed deposits ofsand occurinWilcoxCounty, with the exception ofthe sand bars ofthe Ocmulgee River.

Geomorphic features targeted were the sandbars ofthe Ocmulgee River, and sand hills along the Alapaha River. Seven samples representing six sites were analyzed for aggregate potential in Wilcox County (Fig.173, Table 34). Evaluation Sample Wlx-1 was taken from a sand bar along the Ocmulgee River. Sample Wlx-2 was taken from a preferred soil type. Samples Wlx-3, Wlx-4, Wlx-5a andWlx-5bwere taken from an area ofsand hills. SampleWlx-6 was taken from an area ofsand hills, which coincide with the preferred soil type. None of these samples met ASTM Standard C-33; however, the material represented by sample Wlx1 contains very little fine-grained material and could be upgraded for use as construction aggregate. The remaining samples are too fine-grained for use as construction aggregate. Mining Activity There are no active or recently inactive mining operations in Wilcox County. Summary Evaluation None of the material sampled from the targeted areas metASTM Standard C-33, and there is no evidence ofmining having gone on in the past in Wilcox County. Therefore, the construction material potential for Wilcox County is considered to be low. Wilkinson County Geology and Physiography The surficial sediments ofWilkinson County are derived from the Barnwell Group, the Oconee Group, Quaternary alluvium, and the Altamaha Formation. Wilkinson County lies within the Fall Line Hills District of the Coastal Plain Province. Previous Study Teas (1921, p. 274) reported medium- to coarse-grained sand suitable for concrete in the bed of Big Sandy Creek (Fig.181, Ts-48). Present Study The soil association used in targeting sites for sampling inWilkinson County was Fuquay, and is present as small bodies throughout the county. The geomorphic feature noted is a possible terrace deposit of the Oconee River. Five areas were sampled and analyzed for construction material potential in Wilkinson County (Fig.181, Table 35).

Evaluation Samples Wik-1, Wik-2, Wik-3, and Wik-4 were taken from areas of the targeted soil type. None of these samples met AS1M Standard C-33 because they are all too fine-grained. Sample Wik5 was taken from a 20 acre tract that lies within the preferred soil type and coincides with a possible terrace deposit of the Oconee River. This material also failed AS1M Standard C-33 because it is too well-sorted. Mining Activity The city of Gordon operates a two acre pit (Ffg.181, F-881) from which it produces an average of 10,000 to 50,000 tons of fill material annually. No other information was available for publication. Summary Evaluation The site represented by Wik-5 could provide construction aggregate if upgraded. If the twenty acre tract were mined to a depth of 24 feet, the site could yield up to 1,000,000 tons, before upgrading. The construction material potential for Wilkinson County is considered to be low to moderate. SUMMARY EVALUATION Baldwin, Echols, Hancock, and Pulaski Counties were found to have moderate to high potential for construction aggregate in the study area. In Baldwin County, sample Bal-3 (Ffg.9) represents a possible terrace deposit of the Oconee River. The coarse-grained material covers a 5 acre site to a depth of approximately 9 feet. Ifwashing were necessary, the Oconee River is within 2 miles of this site: Milledgeville is only a few miles away: and a secondary road that could provide transportation is within a few hundred feet of the site. This particular site could provide 98,000 tons of construction aggregate. However, the site is near the Piedmont where crushed stone is readily available for use as construction aggregate. Therefore, the BaldwinCountysite is probablynot attractive as an aggregate source. Pulaski County has two sites that were found to be possible sources for aggregate. The site of sample Pul-2 (Fig.117) is a 50-acre deposit that extends to a depth of 15 feet. It is within 1 mile of both the Ocmulgee River and a major road: thus, providing water and transportation. Sample Pul-5 (Fig.11 7) is representative ofthe several sand bars found along the banks ofthe Ocmulgee River. The one sand bar sampled is approximately 20 acres in extent, and the coarse sand is at least 2 feet thick. In Hancock County, three of the sampled areas of coarse-grained material marginally failed tomeetAS1M Standard C-33 andcould possiblybe upgraded. These sites could be sources for construction aggregate. The site of sample Han-1 (Fig.62) covers 5 acres, and the deposit extends to a depth of approximately 8 feet. This site could provide as much as 70,000 tons of material. It occurs at the bank of a small creek that could provide water for washing, and the site is on a 226 secondary road that could provide transportation. Sample Han-2 (Ftg.62) was from a 5 acre deposit that extends for a depth of approximately 4 feet and could provide as much as 35,000 tons of material. To the west. there is a creekwithin a mile ofthiS site and to the north, a secondary road. An abandoned sand pit is the site of sample Han-3. ThiS deposit iS approximately 10 acres in areal extent, and the material extends to a depth of approximately 8 feet. This site could provide as much as 140,000 tons of aggregate. A creek is within a few hundred feet of this site, but the nearest major road is 5 miles away. The disadvantages of all these deposits are that they all would require some upgrading, and they are all nearthe Piedmontwhere crushed stone iS readily available at a reasonable price. Sample Ech-2b (Fig.56) from Echols County could provide quality construction aggregate, but the removal of 16 feet of overburden probably would prohibit any commercial exploitation ofthis site. Sample Ech-3 (Fig.56) represents a 12 foot deep, 5 acre deposit of coarse-grained sand that could be upgraded for construction aggregate use. The site iS a few thousand feet from a secondary road, which would provide transportation, and within 1000 feet of a creek which could provide water for washing.
