 INTRODUCTION This study is part of a regional investigation of the mineralogy, biostratigraphy, and lithology of the Hawthorne Group. This portion of the investigation consists of the compilation and statistical evaluation of X-ray diffraction data from 713 samples obtained from 28 cores. The results of this study are intended to provide a clay mineral data base from which interpretations concerning the clay mineral origins and distributions can be made. The stratigraphic relationships of the formations which compose the Hawthorne Group and associated formations are shown in Figure 1.

 STUDY AREA AND PREVIOUS WORK 
Interest 1n the clay mineralogy of the Hawthorne Group has been primarily due to the presence of palygorskite and sepiolite. This 1s because palygorskite and sepiolite are: (1) major mineral components of Georgia's econom1c deposits of Fuller's earth (the Fuller's earth 1s stratigraphically equivalent to the Hawthorne Group), (2) rare from the standpoint of worldwide occurrence, and (3) believed to have formed authigenically. 
The study area (Figure 2) was, to some extent, determined by the availability of cores. It was also necessary that the study area 1nelude Miocene-age marine sediments, so as to assure the reliability of stratigraphic correlation (by paleontology). Given these constraints, the geographic area investigated did not include the thick econom1c deposits of palygorskite and sepiolite in southwest Georgia. 
The areas from which the cores were taken are southeastern Georgia, southwestern South Carolina, and northeastern Florida. The Georgia cores were taken from Screven, Effingham, Chatham, Bryan, Wayne, Camden, and Charlton Counties. The cores from Florida were taken from Nassau, Baker, Clay, Bradford, Putnam, and Alachua Counties. The single core from South Carol ina was from Jasper County. General locations of the cores can be found in Figure 2 and specific locations are given 1n Appendix C. 
Previous investigations of the mineralogy of the Hawthorne Group were made by McClellan (1964), Reynolds 0962), Patterson and Buie (1974), Heron and Johnson 0966), Gremi 11 ion (1965), and Weaver and Beck (1977). Semiquant it at i ve estimation of clay mineral abundances are included 1n the studies of McClellan (1964), Weaver and Beck ( 1977), and Heron and Johnson ( 1966). Reynolds (1962) 1n his study

 included relative abundances of clays based on visual estimations from diffractograms. A listing of the minerals found 1n the Hawthorne Group by previous investigators 1s given 1n Table 1. The most comprehensive of the above studies is that of Weaver and Beck, (1977) who conclude that .... "palygorskite and sepiolite were formed 1n brackish water probably under schizohaline conditions. Sepiolite was deposited in the fresher-water environment." 
LABORATORY METI-fODS 
The stratigraphic assignments and samples of the cores were provided by Paul Huddlestun. Approximately one-half of the samples 1vere processed and analyzed hy personnel at the Georgia Institute of Technology. The remainder of the analyses were performed by Georgia Geologic Survey personnel using the same laboratory techniques as were used by Georgia Institute of Technology personnel. Each sample was crushed to a powder and dispersed in deionized water for approximately one minute with a blender. If the suspended clay flocculated after this dispersion, several ml of calgon solution (4mg/100 ml H20) were added and the suspension placed in an ultrasonic bath for several minutes. After a nonflocculating dispersion of the clay was achieved, a gravity separation of the particles smaller than two microns was made. In accordance with the equation of Folk (1955, p. 40), after a settling time of 13 minutes, clay from the top 0.3 em of the suspension was removed with an eyedropper and deposited on a glass microscope slide. 
Each oriented clay slide was saturated with ethylene glycol vapor and then examined by X-ray diffraction. As the 001 d iff rae t ion peak 
5 
 
 areas for kaolinite, illite and smectite* and the 110 diffraction peak areas of palygorskite, and sepiolite are related to the compositional abundances of these minerals (Carrol, 1970, p.65), the areas of these specific peaks were measured using a planimeter and the presence of other minerals noted. In diffractograms where the palygorskite (110) peak overlaps the illite (001) peak or the sepiolite (llO) peak, the peak areas were visually partitioned. 
To correct for the intrinsically low diffraction intensities of illite, kaolinite, palygorskite, and sepiolite, their peak areas were multiplied hy mineral specific constants 1n order to approximate mineral abundance. The constants used for the correction of the illite and kaolinite peak areas are 9.4 and 7.1 respectively (Heath and Pisias, 1979) and the palygorskite and sepiolite constants are 3.0 and 2.0 respectively (Weaver and Beck, 1977). Because crystallinity, particle size, and chemical composition affect the accuracy of such analyses, truly quantitative values for the current study would have required that new constants be established specifically for the sediments examined in this study. Even if such constants had been developed, it is possible the parameters that affect the constants (crystallinity, particle size, and chemical composition) would vary enough with respect to depth (time) to invalidate quantitative measurements of clay mineralogy. Since the establishment of these constants was not feasible, the percentage mineral composition of the clay fractions is semiquantitative. 
*smectite is the name of the group of expandable clay minerals which includes montmorillonite.

 The percentage of each clay mineral in each sample was calculated from the corrected diffraction peak areas of the clay-size fraction. Semi-quantitative clay mineral compositions as well as the occurrences of non-clay minerals are listed 1n Appendix A. The precision of this method (one standard deviation) 1s !2.2, !2.9, and !1.5 percent for smectite, illite, and kaolinite respectively. 
RESULTS The geologic units involved in the analyses, the number of samples examined, and the mean clay mineral compositions are given in Table 2. Similar information is given 1n Table 3 for geologic units for which less than 20 samples were available. Comparisons of the mean clay mineral compositions of var1ous geologic units suggest that there are some obvious clay mineralogy differences between the units, such as, the Marks Head Formation being high in palygorskite. However, examination of the stratigraphic distribution of clay mineral compositions (Sm 
smectite, P =palygorskite, S = sepiolite, I = illite, K =kaolinite, C 
= chlorite) in Figures 3 through 30 indicates that there is a high variability of clay mineral composition that 1s not obviously related to stratigraphic position. Thus, in order to determine which mean clay mineral compositions are significantly different, statistical analyses were performed. 
STATISTICAL ANALYSIS In the statistical analysis the clay mineral composition data were grouped on the basis of stratigraphic occurrence (formations or groups). No consideration was given to the core from which a sample was obtained. Data for any geologic unit which did not contain 20 samples were not analyzed. The cells, stratigraphic horizons, number

 of samples, and variables tested (minerals) are given in Table 2. Similar information is given in Table 3 for geologic units for which less than 20 samples were available. 
In order to determine if there are significant differences between the geologic units with respect to the clay mineral composition, a Kruskal-Wallis one-way analysis of variance of ranks (Siegel, 1956, p. 184-194) was performed for each clay mineral. This is a nonparametric test and it was used because a preliminary examination found that the data are not normally distributed. In each of the Kruskal-Wallis tests, the null hypothesis was that all of the measurements for each variable came from a single population. That is, with respect to the clay mineral under consideration, there is no significant difference between the different geologic units. 
Each clay mineral was tested by a separate Kruskal-Wallis analySlS, For each clay mineral the compositional data from all of the geologic units were ranked by ascending numerical value. The individual values were assigned ranks, with the smallest value having a rank of 1, the next smallest a rank of 2, and so on for each value. The resulting ranks are approximately normally distributed (Dixon and 
Massey, 1969, p. 344). The Kruskal-Wallis statistic H = 12/(N(N+l)) 
~R 2 i/ni - 3(N + l) (Siegel, 1956) was used. In the above equation N is the total number of observations (690), Ri is the sum of the ranks for geologic unit i and ni is the number of observations for geologic unit 1. For each clay mineral, the above equation was used to test the hypothesis that there are no significant differences in clay mineral composition among the seven geologic units evaluated. The H statistic calculated for each mineral 1s given 1n Table 4 along with the critical x2 value. If the H statistic exceeds the x2 value the null hypothesis of equality of the geologic units is rejected.

 The null hypothesis was tested and rejected for each of the clay minerals at the 0.95 probability level. The Kruskal-Wallis test, however, does not provide information as to which geologic units (or unit) are significantly different in clay mineral composition; it only proves that one or more are not equal. In order to determine which geologic units (or unit) were different in clay mineral composition, it was necessary to use a parametric statistical method that is normally used 1n analysis of var1ance as a second step. The method used was Scheffe's method (Guenther, 1964, p. 57) for multiple comparisons (hereafter referred to as the S-method). According to Guenther (1964, p. 58) "An additional advantage associated with this method (S-method) is that i.t i.s known to be affected very little if the assumptions of normality and equal variances are not satisfied." For example, the S- 
method can examine orthogonal contrasts such as 11 7p - 11 6p = 0 where 
11 7p is the mean p (palygorskite) composition of formation 7 (Marks Head) and 116p ts the mean p (palygorskite) composition of formation 6 (Coosawhatchie). The above equation 1s a mathematical expression of the hypothesis that the mean palygorskite contents of the Marks Head and Coosawhatchie Formations are equal. For a lucid discussion of the equations and statistical methods used in testing such orthogonal contrasts, the reader is directed to Guenter (1964, pp. 50-59). 
The S-method test yields two numbers, the upper limit and the lower limit of a confidence interval. If the numerical range defined by these limits includes zero, the data passes the S-method test and the means are not statistically different. The results of S-method tests on the selected hypotheses are significant at the 0.95 confidence level and are given in Table 5.

 The differences of means shown in Table 2 (p.9) were tested for statistical significance. The hypothesis of equal clay mineral composition was tested for each of the following comparisons of geologic units. 
(1) Marine Hawthorne Group Formations = overlying Pleistocene Formations and underlying Oligocene Formations. 
( 2) Marginal marine-nonmarine Al tamaha Formation = mar1ne Haw- 
thorne Group Formations. 
( 3) Marks Head Formation = Parachuc la and Coosawhatchie Forma- 
tions. (4) Parachucla Formation Marks Head and Coosawhatchie Forma- 
tions. Based on these results the following conclusions were made: (1) The marine Hawthorne Group formations are significantly different in palygorskite, sepiolite, illite, and kaolinite contents from the over lying and underlying sediments. (2) The marginal marine-nonmar1ne Altamaha Formation of the Hawthorne Group is significantly different 1n smectite, palygorskite, sepiolite, illite, and kaolinite contents from marine Hawthorne Group formations. (3) The marine Hawthorne Group formations (Coosawhatchie, Marks Head, and Parachucla) are significantly different from each other in smectite, palygorskite, and sepiolite contents. (4) The kaolinite content of the Parachucla Formation is significantly different from the kaolinite content of the Coosawhatchie and the Marks Head Formations. (5) The illite content of the Marks Head Formation is significantly different from the illite contents of the Coosawhatchie and the Parachucla Formations. 
44 
 
 CONCLUSIONS The two pr~mary conclusions of the study are: (1) the mar~ne portion of the Hawthorne Group is unique in its clay mineral composition when compared to associated sediments, and (2) the formations which compose the Hawthorne Group are significantly different from each other in clay mineral composition. These conclusions conform to the conclus~ons of Weaver and Beck (1977) and support the recent revision of Hawthorne Group stratigraphic relationships (Huddlestun, 1982).
