Well Location Map, Gulf Trough Area, Georgia . 7 pocket vii SCOPE AND PURPOSE INTRODUCTION This publication of geologic data in the Gulf Trough area is part of a larger study of the geology and ground-water hydrology of the Gulf Trough conducted by the Georgia Geologic Survey. The purposes of the study are to define the stratigraphy and structure of the Gulf Trough and to evaluate the effect of the Trough on ground-water flow and -- quality in the Floridan Aquifer. As the study progressed, it became apparent that the large volume of geologic information, both previously existing data and new data generated by the study, would be useful to researchers in the Gulf Trough area if published separately. Most of this information 1s 1n the form of 1ithologic logs on file at the Georgia Geologic Survey or the U. S. Geological Survey, Doraville office, and 1ithologic logs of wells recently examined by the authors for this study. The majority of these lithologic logs are descriptions of cuttings or core samples collected from wells and kept by the Georgia Geologic Survey in a sample library. In addition to the lithologic logs, a table 1s presented which summar1zes information on all wells used for this study, both wells for which logs are presented 1n this publication and those with logs published elsewhere. Included 1n this table are identifying names and numbers, locations and elevation data, and the depths to the major time-stratigraphic units within the scope of this study. Addition- ally, well locations are plotted on a 1:500,000 scale base map (back pocket). 1 The Georgia Geologic Survey study of the Gulf Trough is continuing with plans for two publications to follow this data report . The first, on geology, will discuss the stratigraphy and structure of the Gulf Trough. The second publication will cover the ground-water hydrology of the Floridan Aquifer in the Gulf Trough. SOURCES OF DATA Data for this study were gathered from a large number of sources, both published and unpublished. The most frequently used published sourc e s were collections of well logs by Herrick (1961) and Applin and Applin (1964). A summary by Swanson and Gernazian (1979) of petroleum exploration wells drilled ~n Georgia was also useful, providing well location and stratigraphic data. Sources of unpublished data were the files of the Georgia Geologic Survey in Atlanta and the U. S. Geological Survey, Water Resources Division office ~n Doraville, Georgia. The files include unpublished lithologic logs by present and previous staff of the Georgia Geologic Survey and U. S. Geological Survey and a small number of unpublished logs by staff of petroleum exploration companies. Most of these 1ithologic logs also contain useful paleontological information. The records of many wells, especially petroleum exploration wells, include geophysical logs that were used in this study to assist in interpreting stratigraphy. The geophysical logs originate from a wide variety of sources including petroleum industry service companies, private consulting companies, the Georgia Geologic Survey and the U. S. Geological Survey. 2 The majority of wells for which lithologic logs are available have cuttings or core samples stored in the Georgia Geologic Survey sample library. This includes five cores drilled during 1984 and 1985 as part of the current Georgia Geologic Survey Gulf Trough study. Wells for which the Georgia Geologic Survey has samples are assigned a sequential number, referred to as a GGS number. Samples are not available for wells without GGS numbers. METHODS OF STUDY Descriptions of Lithologic Samples The cuttings and core samples examined by the authors of this report fall into several categories. Five of the logs are of new cores drilled by the Georgia Geologic Survey as part of the Gulf Trough study. Another group of wells is represented by samples from petroleum test and water supply wells received by the Georgia Geologic Survey in recent years. These samples have not been examined previously. A number of wells with sample descriptions by previous researchers were reexamined by the authors of this study for the following reasons. In some cases, past descriptions performed for other purposes did not supply sufficient detail for the needs of this study. In others, discrepancies were present in the descriptions of some wells studied independently by two or more previous investigators. Finally, the authors determined that more information could be gained by reexamining samples from certain wells. These include wells which were especially 3 deep, located in a critical area of the Gulf Trough, located 1n an area where new information 1s available, or any combination of these factors. Some specific sample intervals of previously examined wells were reexamined by the authors where the original description did not provide adequate detail to determine stratigraphic contacts. These short redescribed sections are not presented in this report, but were used in many instances to reinterpret stratigraphic correlations from the original log. Wells for which this has been done are noted in the data summary table. The authors' evaluation of previous workers' descriptions in some instances led to a reinterpretation of stratigraphic boundaries of the original log. This was not uncommon 1n v1ew of the authors' efforts to consistently apply a set of criteria for identifying stratigraphic units to geologic descriptions of a diverse group of prev1ous investigators over a period of many years. Situations where the authors changed the stratigraphic boundaries from the original logs of previous workers also are noted in the data summary table. Sample Examination Methods Cuttings and core samples were examined microscopically for lithologic descriptions and paleontological identifications. In the case of cuttings, the samples were first sieved (U. S. Standard Sieve Series #20 (0.85 mm), #40 (0.42 mm), and #80 (0.177 mm)) for ease of exam1nation and to avoid the tendency to place too much emphasis on the larger s 1ze fraction. The samples were described lithologically on a form 4 developed by the authors to standardize the descriptions. Sample colors were noted using the Rock Color Chart distributed by the Geological Society of America. Chemical tests used were a 10% hydrochloric acid solution and a calcite stain, to assist 1n the identification of calcite and dolomite, and a phosphate test solution. Microfossils were removed from the sample and placed on slides for identification. The samples, were described at the interval in which they were collected, most commonly 10 feet in the case of cuttings. Cores were described for the sample interval recovered. The logs presented in this report are summar1es of those detailed logs. In the case of core samples, it was possible to do more detailed work. The cores were described microscopically in a manner similar to the cuttings. In addition, the Miocene sections of some cores were sampled and the m1nus one m1cron clay faction examined by x-ray diffraction. This was done to provide more informat ion on the clay mineralogy of Miocene stratigraphic units and on Miocene depositional environments. Also, some samples were sent to L. E. Edwards of the U.S. Geological Survey for age determination based on dinoflagellate assemblages. Stratigraphic Correlation The goal of the authors 1n exam1n1ng well samples and the descriptions of previous workers was to identify and correlate timestratigraphic boundaries. These include the tops of the Oligocene, upper Eocene, middle Eocene, lower Eocene/ Paleocene, and Cretaceous. However, where the quality of samples permitted, 1ithostrat igraphic names have been recorded on the logs. Generally, the authors followed the stratigraphic nomenclature and correlation presented by Huddleston (1981 and in prep.) 5 Stratigraphic boundaries were determined using lithologic, paleontological, and geophysical evidence. The authors conferred in an effort to consistently apply criteria. In general, efforts were made to correlate from wells with reliable stratigraphic contacts to other wells in the vicinity. For example, a core with lithologic, paleontological, and geophysical data would be used to assist 1n determining stratigraphic contacts in a number of nearby wells with less data. Such correlation was generally possible provided care was taken to correlate among wells in the same position relative to the Gulf Trough (i.e. along the strike of the Trough). Facies changes are known to occur over relatively short distances across the Trough, making corelation difficult. The use of lithologic, paleontological, and geophysical criteria 1n determining stratigraphic contacts 1s discussed 1n more detail in the introduction to the data table. STUDY AREA DESCRIPTION The Gulf Trough area includes 27 counties extending southwest to northeast across the Coastal Plain of Georgia from Decatur, Grady, Thomas, and Brooks Counties along the Florida border to Screven and Effingham Counties along the South Carolina border (see Plate 1). The total area of the 27 counties is 11,546 square miles. The study area extends across five physiographic districts of the Coastal Plain province (Fig. 1). Most of the study area lies 1n the Tifton and Vidalia Upland physiographic districts. These are topographically high areas of the Coastal Plain with elevations ranging up to 500 feet, and sloping downward toward the coast to 100 feet.

The northern boundary of these two physiographic districts generally corresponds to the updip limit of Neogene sediments. The southern boundary follows the drainage divide of the Altamaha River and the Orangeburg Escarpment. Parts of Decatur, Mitchell, Grady, and Worth Counties 1n the extreme southwest of the study area are in the Dougherty Plain, a relatively flat, low-lying karstic area of the Coastal Plain. The Dougherty Plain is separated from the Tifton and Vidalia Upland districts by the Pelham Escarpment. In the central part of the study area, parts of Irwin, Jeff Davis, Coffee, Bacon, and Appling Counties are in the Bacon Terraces physiographic district. This area 1s characterized by a ser1es of relatively subtle, dissected, southwest-northeast trending mar1ne terraces. Finally, in the extreme northern part of the study area, sections of southern Bulloch and Screven Counties and all of Effingham County lie in the Barrier Island Sequence physiographic district. This area has been influenced by Pleistocene sea level fluctuations and is characterized by relatively low land surface elevations ranging from 160 feet in southern Bulloch and Screven counties to less than SO feet 1n Effingham County. This physiographic district is separated from the Vidalia Upland by the Orangeburg Escarpment. Several major Georgia rivers cross or bound the study area. The Flint River flows through the extreme southwestern edge of the area. The Ocmulgee and Oconee Rivers merge to form the Altamaha River within the study area. Finally, the Ogeechee and Savannah Rivers cross the northern end of the study area. The study area is basically rural in nature with agriculture being the major economic activity. The population is rural with concentra- 8 tions in small cities and towns. Eight cities have populations over 10,000 according to the 1980 U.S. Census (Bainbridge, Thomasville, Moultrie, Tifton, Fitzgerald, Vidalia, and Statesboro). Only Moultrie (15, 708) and Thomasville (18,463) have populations over 15,000. The total population of the 27-county study area was 476,000 in 1980. Geologically, the Coastal Plain of Georgia is composed of a wedge of clastic and carbonate sediments ranging in age from Jurassic(?) or Cretaceous to Recent. This sedimentary wedge ranges in thickness from a feather edge along the Fall Line to 7000 feet 1n southwestern Georgia. The Coastal Plain sediments lie unconformably on a basement of Piedmont crystalline rocks, Triassic red beds and volcanics, and Paleozoic sedimentary rocks. The Gulf Trough is a long, narrow feature of the Georgia Coastal Plain where anomalous thicknesses and abrupt facies changes in Tertiary sediments are known to occur. The Trough itself is as narrow as 6 to 8 miles in places, but broadens to 30 to 40 miles at its southern end, where it merges with the Apalachicola Embayment. The Miocene ser1es, typically about 200 feet thick in areas immediately adjacent to the Gulf Trough, 1s over 700 feet thick locally within the Trough. Oligocene sediments average about 100 feet in thickness outside the Trough, but are commonly over 500 feet thick in the Trough. The Gulf Trough has a significant impact on ground water 1n the Floridan Aquifer, which in the area is composed of Oligocene and upper Eocene limestones. Transmissivity and well yields are low relative to areas outside the Trough. A pronounced increase in hydraulic gradient is evident along the Gulf Trough on potentiometric maps of the Floridan Aquifer (Krause and Hayes, 1981). Ground-water quality also 1s 9 affected, with areas of high sulfate, natural radioactivity, and barium associated with the Trough. Locally, water produced from the Floridan Aquifer does not meet Georgia's safe drinking water standards for these constituents. ACKNOWLEDGEMENTS The authors extend their thanks to Lucy E. Edwards of the U.S. Geological Survey, Reston, Virginia. Her work, using dinoflagellate assemblages, is a valuable contribution to our understanding of Gulf Trough Area stratigraphy. We also thank Harold E. Gill of the U.S. Geological Survey, whose rev1.ew of this report led to a number of improvements. Finally, we wish to express our thanks to all those individuals and municipalities who supplied in format ion and access to their wells, especially those who assisted our efforts by allowing core drilling on their land. The help of all these people has made the conduct of this study much less difficult. PREVIOUS INVESTIGATIONS Although the term "Gulf Trough of Georgia" was first proposed by Herrick and Vorhis in 1963, the feature was known to geologists earlier than that. Previous references, however, were vague and incomplete, and it is obvious that considerable confusion was caused by multiple names being assigned to the same feature. The Apalachicola Embayment, of which the Gulf Trough appears to be a narrow northeastward extension across Georgia, was first described by Johnson (1892), who used the 10 name "Chattahoochee Embayment". Johnson recognized this as a structurally low area of northwestern Florida. Stephenson (1928) and Leet (1940) both extended this low area into southwestern Georgia, referring to it as a syncline. Applin and Applin (1944) also noted this feature extending into southwest Georgia, but referred to it as structural in origin. The feature was described as a belt of thick Tertiary sediments by Pressler (1947), who named it the "Apalachicola Embayment of the Gulf Basin". Murray, in 1961, referred to the same feature as the "Southwest Georgia Basin". Stringfield (1966) named it the "Apalachicola Basin" while the name "Apalachicola Embayment" has been used by several workers including Puri and Vernon (1964), Hendry and Sproul (1966), and Sever, Cathcart, and Patterson (1967). Although several workers recognized the Apalachicola Embayment as an area of thick Tertiary sediments extending into southwest Georgia, it was Toulmin (1952) who first realized that a narrow extension of anomalously thick Miocene sediments continued northeastward into Georgia at least as far as Tift County. Herrick and Vorhis (1963) also mapped this ext e nsion of thick Miocene sediments, referring to it as the "Gu 1f Trough of Georgia". Several subsequent workers used that name for the feature, including Hendry and Sproul (1966), Sever, Cathcart, and Patterson 0967), Sever (1964, 1966a, 1966b), Owen (1963), Gelbaum (1978), Gelbaum and Howell (1982), and Miller (1982). Zimmerman (1977) refers to this same feature as the "Suwannee Strait", although this name was previously used in reference to an older feature located farther east. Gelbaum (1978) extended the Gulf Trough across the Georgia Coastal Plain to Screven and Effingham Counties mainly on the indirect evidence of potentiometric data for the Floridan Aquifer. 1 1 A series of maps based on well data was presented by Gelbaum and Howell ( 1982) to show the Gulf Trough extending to Screven and Effingham Counties on the Georgia-South Carolina border. Several theories have been advanced on the origin of the Gu 1 f Trough. These include structural theories, usually referring to the Trough as a downfaulted area or graben, the theory that the Trough was a marine strait similar to the present-day Straits of Florida, and the theory that limestone solutioning played a major role in the development of the Trough. Fault movement, at least locally, ~n the Gulf Trough was proposed by Sever ( 1964, 1966a, and 1966b), Hendry and Sproul (1966), and Miller (1982). Gelbaum and Howell (1982) refer to the Trough as a depositional feature with local areas of downfaulting. The concept of a marine strait was favored by Rainwater (1956) and Zimmerman 0977), although Zimmerman also extended the Ochlocknee Fault of Sever (l966a, 1966b) into Colquitt County. Limestone solutioning was proposed by Toulmin and Winters (1954) and Stringfield (1966). 12 REFERENCES Applin, E. R. and Applin, P.

The majority of the wells are GGS wells (wells for which the Georgia Geologic Survey has lithologic samples), but the table also contains information on non-GGS wells. The table represents those wells for which the best and most complete information was available, and for which it was possible to make stratigraphic correlations. FORMAT DESCRIPTION Well Identification and Location Data The following is a description, by column, of the format of the well identification and location data. 1) The name of the county in which the well 1s located. Wells are arranged alphabetically, by county. 2) The GGS number, where appropriate. Wells within each county are arranged numerically by GGS number. Wells having no GGS number follow the listing of GGS wells. 3) The well name. Wells are named for the most recent owner on record, or in the case of cores drilled by the Georgia Geologic Survey, are assigned county numbers. 4) The latitude and longitude. These listings represent the best available location in format ion, in many cases verified in the field. The letter "e" designates an estimated location. 5) The land surface altitude, in feet, above mean sea level (L.S. Alt. (ft.)). These values are derived by plotting the latitude and longitude of each well on U. S. Geological Survey 7. 5minute topographic quadrangle maps. They are as accurate as 19 the location data and accuracy of the 7.5- minute map series (+ 1/2 contour interval) allow. The letter "e" designates an estimated land surface altitude based on estimated locations. Stratigraphic Data The remainder of the table 1s divided into five columns, each headed with the name of a major time-stratigraphic unit. These are 1) Oligocene 2) upper Eocene 3) middle Eocene 4) lower Eocene/Paleocene, and 5) Cretaceous. Each of these columns 1s subdivided into two columns. The lefthand column shows the depth below land surface, 1n feet, to the top of the unit, and the righthand shows number and letter codes indicating the criteria used to determine the unit top, and the source from which the information was drawn. Because this table lists unit tops only, the Miocene, although a focus of this report, does not appear. The Miocene crops out throughout much of the study area, making determination of the top of the unit impossible in most cases due to eros1on. In cases where a unit 1s not present 1n the stratigraphic section represented in a well, the word "None" is used in the depth column on the data table. The letter "a" preceeding the depth to top indicates that the contact 1s above the depth listed. This is due to missing samples, or to erosion of the upper surface of the unit. The letter "b" preceeding the depth to top indicates that the contact is below the depth listed. This is due to missing samples, or to the completion of the well at a depth insufficient to reach the contact. The criteria applied 1n determining contacts are of three general types: paleontological, geophysical, and lithological. These are 20 gtven the number codes 1, 2, and 3, respectively. Special situations, explained below, are given the number codes 4 through 6. The Criteria and Source column lists as many of these codes as apply to each stratigraphic contact. The sources of data used for identifying stratigraphic contacts are given the letter codes A through N. These codes are listed immediately preceeding Table l. For, example, the listing 1,2/B indicates a contact identified, using paleontological and geophysical data, by the authors of this report and published herein. Paleontological Criteria (1) Correlations on the basis of paleontological criteria were made wherever permitted by the presence and preservation of faunal remains. In this study, the primary sources of paleontological control are the foraminifers present in cuttings and core samples, and, 1n core samples only, the dinoflagellate assemblage. Foraminiferal identifications were made by the authors, or drawn from published and unpublished sources credited in the data table. In many cases, specific identifications of the foraminiferal remains were not made, particularly of the larger foraminifers. For purposes of this study, genertc identifications were often adequate to make stratigraphic correlation possible. The faunal 1ist s for each well are available at the Georgia Geologic Survey. The major time-stratigraphic units in the Gulf Trough study area are identified or characterized by the presence of one or more of the 21 following foraminiferal genera or species: OLIGOCENE Asterigerina subacuta Dictyoconus sp. Pararotalia mex~cana Lenticulina vicksburgensis Pararotalia byramensis Nummulites panamensis Lepidocyclina sp. UPPER EOCENE Asterocyclina sp. Eponides jacksonensis Lepidocyclina ocalana Lepidocyclina sp. Nummulites floridensis MIDDLE EOCENE Cibicides westi LOWER EOCENE/PALEOCENE Eponides dorfi Morozovella acuta CRETACEOUS Rugoglobigerina sp. Anomalina pseudopapillosa Globotruncana sp. Lenticulina navarroensis The dinoflagellate spec~es, recovered from samples taken from Gulf Trough project cores, were identified by L. E. Edwards of the U. S. Geological Survey. Lists of these species form a part of the Gu 1f Trough project files, at the Georgia Geologic Survey, Atlanta. 22 Because of the large number of well logs described by S. M. Herrick and the wide use of these logs, it LS necessary to discuss Herrick's identification of the foraminifer Asterocyclina. Most published identifications of Asterocyclina were checked by the authors. In cases where the presence of this fossi 1 could not be verified, it was excluded from consideration ~n determining stratigraphic contacts. For this reason, the authors' interpretation of the top of the Eocene may differ from that of Herrick (1961) even where Herrick cites the presence of Asterocyclina in the samples. Geophysical Criteria (2) Many of the wells used ~n the study have geophysical logs which were run at some time after the well was drilled. A wide variety of logs are available, however the most connnonly run logs, and the most frequently used for stratigraphic correlation in this study, are electrical and natural gamma logs. The type, quality, and format of these logs vary widely because the logs originated from different sources, using a variety of equipment. Correlations usLng geophysical logs can be made reliably among some wells in the Gulf Trough study area. Because geophysical response 1s partly controlled by lithology, facies changes known to occur in the Trough (see discussion of lithologic criteria) affect geophysical signatures. The result is that geophysical logs sometimes cannot be correlated even over relatively short distances. On the other hand, geophysical logs can be remarkably similar over distances of tens of miles for wells parallel to the trend of the Gulf Trough. The practice among the authors of this report was to use geophysical logs to correlate from wells which had supporting paleontological and lithologic data to nearby wells for which supporting data were missing or insufficient. Lithologic Criteria (3) Correlations on the basis of lithologic criteria can be difficlut and unreliable in the study area of the Gulf Trough. Facies changes are known to occur over relatively short distances, especially crossing the trend of the Trough, and lithologies at time-stratigraphic contacts are not consistent. However, lithologic criteria can be used reliably among nearby wells if one or more of the wells have supporting paleontological and/or geophysical information. This 1s especially true if the wells are located in the same position relative to the Gulf Trough (i.e. located parallel to the trend of the Trough). Unfortunately, correlations sometimes had to be made on the basis of lithologic criteria alone where nearby wells with supporting information were not available. In cases where a lack of supporting information made it impossible to correlate with confidence, the correlation was not made. Other Criteria (4-6) There are several situations where time-stratigraphic unit boundaries cannot be accurately determined, but where an approximation of that centact would be useful. This occurs where (4) the contact is 24 tn a large sample gap, (5) where the contact ts below, but ts inferred to be near the bottom of the well, and (6) where the contact ts above the land surface at the well site, i.e. the contact has been removed by erosion, and the well samples begin in a particular unit. 25 Sources (A-N) The Criteria and Source columns of the following data table (Table 1) also contain coded information on the source of each time stratigraphic boundary interpretation. A set of letter codes, A-N, identifies the source from which stratigraphic criteria are drawn. They are as follows: A. Applin and Applin (1964). B.

Most commonly, these logs are from previously unpublished records of the Georgia Geologic Survey and U. S. Geological Survey. Many of the logs are descriptions by the authors of wells which have not been described previously. These are either new samples collected for this study, recent petroleum exploration wells, or water supply wells. A small number of logs are .....=-- redescriptions by the authors of well logs available 1n published reports. Well logs written by people other than the authors of this report have been, in many cases, extensively edited. The goal of this editing has been to produce well logs that are in a consistent format, with similar style and content. In some cases, the authors reexamined critical intervals of well samples to supply additional information. The well logs are arranged alphabetically by county and numerical- ly by GGS number within each county. Non-GGS wells (wells for which tl1e Georgia Geologic Survey does not have samples) are arranged follow- ing the GGS wells in each county. FORMAT DESCRIPTION The heading for each log contains the following information: 1) GGS number 69 2) Well name - this 1s the name of the most recent owner according to records at the GGS and U. S. Geological Survey. 3) County 4) Altitude - indicates the land surface elevation in feet at the well site, as determined by plotting well locations on U.S. Geological Survey 7.5-minute topographic quadrangle maps. Locations are from GGS and U. S. Geological Survey files, including many that have been verified by GGS or U. S. Geological Survey personnel. 5) Total depth (in feet) below land surface 6) Described by - indicates the source of the well log as follows: a) GGS - indicates sample description by one or more of the authors of this report b) GGS, previous investigator indicates sample description by Georgia Geologic Survey personnel contributing well logs to a general data base, or to the files of a previous project (C. S. Gelbaum, J. E. Howell, J. A. Kellam, T. W. Watson) c) S. M. Herrick, C. W. Sever, or Vaux Owen - indicates sample description by these individuals either on contract with the GGS or on cooperative projects between the GGS and U. S. Geological Survey. The body of the log is divided into five columns. The two 1e f t - hand columns, bearing the heading "Summary", are reserved for forma- tional contacts and time-stratigraphic information. The Summary column is divided into two parts. The left column, headed "This Report", contains the authors' stratigraphic interpretation. It includes the geologic epoch (or period in the case of Cretaceous and older units) to which the unit has been assigned, the group and formation names, where these have been differentiated, and the depth, in feet below land surface, to the top of the unit. Due to space limitations, the desig- nat ions "group" and "format ion" have been dropped. The reader 1s referred to Huddleston (1981) for a stratigraphic correlation chart of these units. 70 The right Summary column is reserved for stratigraphic interpretations of non-GGS workers (Herrick, Sever and Owen). In this case, the authors of this report have studied the original descriptions and made new interpret at ions. These interpretations, which may or may not co inc ide with those of the original workers, are presented 1n the column headed "This Report". In logs attributed to the GGS, the right Summary column remains blank. In cases where the top of the geologic units could not be deter- mined, the word "In" is used preceeding the geologic epoch, for example "In Miocene". This situation occurs where the top of the unit ...:-- has been removed by erosion, so that the first recovered samples start in a particular unit. This 1s also used where large gaps in the recovered samples prohibit the determination of a contact. In this case, the next deeper recovered sample may be 1n a lower unit. Small sample gaps (approximately 20 ft or less) which occurred at geologic contacts were usually assigned to the next lower unit on the theory that loss of drilling circulation (and therefore samples) commonly occurs at the top of formational contacts. It was sometimes possible to determine the location of contacts using geophysical logs where samples were missing or where age and formation could not be determined from the samples alone. An asterisk (*) is used in the Summary column where geophysical logs were used to determine the contact. The center column of each log is reserved for the sample descrip- t ion. In the descriptions of cuttings or core, the dominant 1itho 1- ogies are capitalized and listed in order of decreasing abundance 1n the sample. In cases where short intervals within a bed or unit differ 1ithologically from the rest of the unit, they are described and 71 listed, with appropriate depths indicated, below the matn body of the description for each bed. The fauna found within each sample interval are described in a general way tn the matn body of the 1ithologic description. For example, an interval might be described as ''Limestone: fossiliferous, with fragments of echinoids, bryozoans, and foraminifers". Where microfossils, chiefly foraminifers, were used for stratigraphic interpretation and control, they are identified by genus and (where necessary) by species name. They are listed, along with the depth found, following the description of each bed. No attempt was made to produce an exhaustive catalogue of all species present in the samples. The fossils identified are those which are diagnostic or representative of a range of geologic time or an environment of deposition. For several of the cores collected for this study, samples were sent to L. E. Edwards, U. S. Geological Survey, for age determination based on examination of dinoflagellates. These are noted at the appropriate location on each log. However, the actual lists of fossils identified by L. E. Edwards are not presented here because of their length. The lists are on file with the Georgia Geologic Survey and with the U. S. Geological Survey, Reston office. The two right-hand columns of the well logs supply information on the thickness of individual beds within each well and the depth to the bottom of the interval described using land surface as the datum. Both thickness and depth measurements are given in feet. 72 WELL NO: GGS 410 WELL NAME: J. W. Gaskins COUNTY: Atkinson SUMMARY: THIS REPORT 1-l:RR ICK DESCRIPTION ALTITUDE: 295 ft.
