Core Drilling Project: Lee, Hendry
and Collier Counties

INTRODUCTION

In June 1988, the Florida Geological Survey (FGS) and the

South Florida Water Management District (District) entered into a

contract (#88-188-0675) to conduct a joint project in Lee, Hendry

and Collier Counties. The objectives of this project were: to

increase the geologic/hydrogeologic well data available in these

counties, to translate existing lithologic descriptions of wells

within the district to computer format and to add this data to the

District computer data base. These objectives were met by the

translation of over 180 existing well logs to computer format, by

drilling and evaluating the data for six cores, and merging all of

this data with the existing FGS and District computer data bases.

Six cores were drilled by the FGS at locations specified by

the District (Figure 1). Geophysical logs were run on each core by

District personnel. After completion of drilling and logging, five

of the coreholes were plugged by District contractors. The

remaining corehole was reamed and a monitor well constructed. The

cores are listed below:

LITHOSTRATIGRAPHY

Suwannee Limestone

The Oligocene-age Suwannee Limestone underlies all of Lee,

Hendry and Collier Counties, consisting of white to beige

recrystallized limestone containing abundant microfossils, quartz

sand and trace amounts of phosphate. The top of the Suwannee

Limestone is encountered between 550 and 1000 feet below National

Geodetic Vertical Datum (NGVD), with the shallowest occurrences

being in northwest Lee County and the deepest in central Hendry

County (Wedderburn et al., 1982; Peacock, 1983 and Klein et al.,

1964). Sediments of the Suwannee Limestone form part of the

Floridan aquifer system. The Suwannee was encountered in both Lee

County cores (W-16242 and W-16523) (Figures 2, 7-9). The pick for

the top of the Suwannee Limestone was based upon an overall

LITHOSTRATIGRAPHY

Suwannee Limestone

The Oligocene-age Suwannee Limestone underlies all of Lee,

Hendry and Collier Counties, consisting of white to beige

recrystallized limestone containing abundant microfossils, quartz

sand and trace amounts of phosphate. The top of the Suwannee

Limestone is encountered between 550 and 1000 feet below National

Geodetic Vertical Datum (NGVD), with the shallowest occurrences

being in northwest Lee County and the deepest in central Hendry

County (Wedderburn et al., 1982; Peacock, 1983 and Klein et al.,

1964). Sediments of the Suwannee Limestone form part of the

Floridan aquifer system. The Suwannee was encountered in both Lee

County cores (W-16242 and W-16523) (Figures 2, 7-9). The pick for

the top of the Suwannee Limestone was based upon an overall

decrease in quartz sand and phosphate, an overall increase in

fossil content, and a general increase in carbonate lithology from

a mudstone or wackestone to a packstone or grainstone.

Hawthorn Group

The Miocene-Pliocene age Hawthorn Group unconformably overlies

the Suwannee Limestone. Scott (1986, 1988) raised the Hawthorn

Formation to Group status and erected new formations within the

Group statewide. The Hawthorn Group in south Florida consists of

two formations: the Arcadia Formation (Hawthorn carbonate unit and

Tampa Limestone of previous usage) and the Peace River Formation

(Hawthorn siliciclastic unit of previous usage).

Arcadia Formation

The Arcadia Formation consists predominantly of white, light

gray and yellowish gray, poorly to well indurated, calcilutitic and

very finely crystalline limestone (wackestone to mudstone),

dolomitic limestone and dolostone. The Arcadia contains variable

amounts of clay, silt, quartz and phosphate sand with occasional

phosphate gravel. Beds of clay, silt-sized dolomite and quartz

sand are common. The Arcadia is commonly fossiliferous (primarily

oysters, pectens and bryozoans, with diatoms and foraminifera in

some clayey intervals). The top of the Arcadia is found at

approximately 150 feet below NGVD in northwestern Lee County and

dips to the southeast to over 400 feet below NGVD in southeastern

Collier County (Scott, 1988). The Arcadia Formation was

encountered in all six of the cores drilled for this project

(Figures 2-10). The top of the Arcadia Formation in these cores

was picked based upon a change from predominantly siliciclastic

sediments to predominantly carbonate sediments.

Peace River Formation

The Peace River Formation (Scott, 1988) consists of the "upper

Hawthorn siliciclastics" of prior usage as well as the

siliciclastics previously placed in the Tamiami Formation (Parker,

1951, Parker et al., 1955) and the Murdock Station and Bayshore

Clay Members of the Tamiami Formation (Hunter, 1968). The Peace

River Formation consists primarily of white, light gray and light

olive, interbedded, poorly to moderately indurated sands, silts,

clays and carbonates. The siliciclastic components are dominant.

Carbonate material is primarily calcilutite or silt-sized dolomite.

All lithologies typically contain variable amounts of quartz and

phosphate sand. The top of the Peace River Formation is

encountered at approximately 0 feet NGVD in northern Lee County

dipping slightly to the south-southeast in Lee and Hendry Counties

then to the southwest in Collier County where it is found

predominantly between 100 and 150 feet below NGVD (Scott, 1988).

The Peace River Formation was encountered in all six cores. In

three of the cores (W-16242, W-16387, and W-16523) (Figures 2, 3,

6-10) the top of the Peace River Formation was picked as a change

from sandy limestones of the Tamiami Formation to very fine to fine

sands, silts, and clays with minor phosphate and carbonate. In the

three remaining cores (W-16329, W-16434, and W-16505) (Figures 3-5,

8, 10), the presence of thick sequences of coarse siliciclastics

made the picking of the top of the Peace River Formation difficult.

In general, the Peace River Formation pick in these cores was made

based upon a decrease in grain size from the medium to very coarse

sands of the "Miocene coarse clastics" to very fine to fine sands

with minor phosphate and carbonate. This pick is made more

difficult in these three cores due to the fact that the recovery of

sediments in this interval was generally poor, with most of the

samples consisting of bags of cuttings which represented five feet

or more of samples.

Sediments of the Hawthorn Group form the both intermediate

aquifer system and intermediate confining unit which includes the

mid-Hawthorn aquifer and sandstone aquifer, and the lower, mid- and

upper Hawthorn confining zones (Wedderburn et al., 1982; Smith and

Adams, 1988). The confining characteristics of the Hawthorn Group

sediments also serve to confine the Floridan aquifer system. Water

from the producing zones in the Hawthorn is better quality in

general than the underlying Floridan aquifer system (Wedderburn et

al., 1982).

Undifferentiated Coarse Siliciclastics

A thick sequence of coarse quartz sand and gravel is present

in Hendry and Collier Counties which, in the past, has been

informally called the "Miocene coarse clastics" and placed in the

upper part of the Hawthorn Formation (Peacock, 1983) or Peace River

Formation of the Hawthorn Group (Knapp et al., 1986; Smith and

Adams, 1988; Campbell, 1988). In addition to being informal, the

term "Miocene coarse clastics" is misleading as at least part of

this unit is probably Pliocene in age. Three cores (W-16329, W-

16434, and W-16505) (Figures 3, 5-6, 8, 10), all had a thick

sequence of coarse siliciclastic material present overlying the

Peace River Formation. These siliciclastics are

uncharacteristically coarse for the Peace River Formation, and have

been referred to as undifferentiated sands, clays and shells until

further information becomes available for the area.

Smith and Adams (1988) report that these coarse siliciclastics

form a northeast-southwest trending trough on top of the fine sands

and silts of the Peace River Formation in Hendry and Collier

Counties. These three cores fall along the axis of this trough.

The top of the coarse siliciclastics in these three cores range

from approximately 50 to 70 feet below NGVD, with a thickness of

290 to 300 feet (Figures 8 and 10). These thicknesses are

considerably greater than the ones shown by Smith and Adams (1988).

This may be due to the fact that large portions of the recovery in

the coarse siliciclastic section consists of cuttings which have

been homogenized and have potentially had fine grained matrix

material washed out during drilling, thus making the contact

between the base of the coarse siliciclastic material and the top

of the Peace River Formation difficult to pick with certainty.

Tamiami Formation

The Tamiami Formation of Parker (1951) and Parker et al.

(1955) has been restricted by later authors .(Hunter, 1968; Hunter

and Wise, 1980 a and b; Scott, 1988). The Tamiami as used in this

report reflects these changes and consists of the Ochopee and

Buckingham Limestone Members and the Pinecrest Sand Member. Some

difficulty arises in identifying the Tamiami where sand sediments

are devoid of shell material and recognizable limestone units are

not present.

The Tamiami consists primarily of yellowish gray, shelly,

quartz sandy, slightly phosphatic limestone with calcilutite or

recrystallized calcite matrix. Molds of aragonitic fossils are

common. Quartz sand, shell content and induration are variable.

The top of the Tamiami Formation in the area ranges from a

high of approximately 25 feet above NGVD in eastern Lee County to

as much as 45 feet below NGVD along the coastal portions of Lee

County (Wedderburn et al., 1982), and as much as 60 feet below NGVD

in southeastern Hendry County. Elsewhere the Tamiami is found

primarily between 0 feet NGVD and 20 feet above NGVD (Knapp et al.,

1986; Smith and Adams, 1988). The Tamiami Formation is missing in

the northwest and northeast corners of Hendry County (Smith and

Adams, 1988). The Tamiami Formation was encountered in all of the

cores except for W-16329 (Figures 2, 4-10), where it is apparently

absent. The top of the Tamiami Formation was picked as being a

moderately sandy to very sandy yellowish gray shelly limestone with

numerous fossil molds. In W-16523, the Tamiami Formation was much

sandier than in the other cores. In this core, the Tamiami

Formation is a very calcareous, slightly phosphatic, fine grained

quartz sand.

Caloosahatchee and Fort Thompson Formations

The Caloosahatchee and Fort Thompson Formations of previous

usage are undifferentiated in this report due to the lack of

lithologic characteristics on which to differentiate the units.

These units were originally defined based on the fossils they

contain. The fossiliferous sands and carbonates of these units are

often less than 10-feet thick. The undifferentiated Caloosahatchee

and Fort Thompson Formations are present in two of the cores from

the study (W-16387 and W-16505) (Figures 4, 6, 8 and 10). These

formations are poorly represented in these cores. The tops of

these formations were picked as a moderately to highly

recrystallized, slightly sandy, fine-grained limestone.

Undifferentiated Sands, Clays and Shells

Undifferentiated Pleistocene-Holocene age sediments overlie

the Caloosahatchee-Ft. Thompson sediments or the Tamiami Formation

in each of the cores from this study. These sediments vary from

unfossiliferous quartz sands to very fossil.iferous sands and shell

beds, thin "marl" beds and organic-rich sediments. The undif-

ferentiated sediments generally occur as thin beds less than 10-

feet thick. However, along the coast these units can exceed 20-

feet thick.

Sediments belonging to the undifferentiated coarse

siliciclastics, Tamiami, Caloosahatchee and Ft. Thompson Formations

and the undifferentiated sands and clays comprise the surficial

aquifer system (Wedderburn et al., 1982; Knapp et al., 1986; Smith

and Adams, 1988). The surficial aquifer system contains two

aquifers, the water table and lower Tamiami which are separated by

a leaky confining zone (Tamiami confining beds).

CORE AND CUTTINGS-DESCRIPTIONS

Lithologic descriptions utilizing the Well Log Data System

were made for the six cores drilled for this study and entered in

the Florida Geological Survey's wellfile data base. A binocular

microscope was utilized in describing the lithologic

characteristics of each of the cores. The major characteristics

described and recorded included sample color, porosity, lithology,

induration, cement type, accessory minerals, and fossils.

Formation tops were determined based primarily on lithologic

criteria. Rock colors were based on the Geological Society of

America's Rock Color chart (Geological Society of America, 1984).

Appendix I contains complete lithologic descriptions of each of the

six cores described in this study.

RADIOCHEMISTRY AND X-RAY DIFFRACTION STUDIES

In addition to the microscopic description of the cores,

selected samples from one of the cores, W-16242, are currently

being analyzed for their uranium concentration and U234/U238 activity

ratio as part of the research for a Master's thesis at Florida

State University. As part of this thesis, it was decided to

analyze the bulk mineralogy of these samples in order to determine

what relationship, if any, the mineralogy has with the distribution

of uranium within the sediments. For this reason, each of the

twenty-six samples chosen for uranium work was analyzed for bulk

mineralogy by means of an x-ray diffractometer (XRD). The clay-

sized fraction from each of these samples will be analyzed in order

to determine the specific clay minerals present.

Selected intervals from the remaining five cores from this

study were also sampled for XRD analysis of their bulk mineralogy.

Due to the presence of thick intervals of coarse siliciclastic

material in three of the cores, (W-16329, W-16434 and W-16505)

there are large gaps in the intervals chosen for XRD analyses of

bulk mineralogy. In general, the intervals chosen for XRD analysis

were those in which the mineralogy was uncertain based upon visual

inspection of the core under a binocular microscope. X-ray

diffraction studies are useful for the identification of the

various minerals in a sample, but are semi-quantitative, at best,

for determination of the mineral abundance or percentage. In order

to analyze the bulk mineralogy of the samples, approximately 20-30

grams of the sample was ground to a fine powder. This procedure

insured homogeneous mixing of the sample and reduced the chance of

preferential orientation of certain minerals during analysis. A

split from the sample was then placed in a planchet (sample holder)

and placed into the x-ray diffractometer. The diffractometer

records the x-ray reflections as peaks, both in digital and analog

form. Every mineral exhibits a characteristic series of peaks,

which are used to determine the presence of the mineral. The x-

ray pattern for each sample begins at a 2-theta angle of four

degrees so that all major mineral peaks could be identified.

The results of the XRD analysis are listed in Table 1. The

sample depth is listed in the first column of each table. The

subsequent columns are for the minerals identified. Mineral

abundances were determined from the relative peak heights. When

possible, estimates of relative abundances were made, with 1, 2,

3... representing abundance in descending order. Two forms of

calcium carbonate (Caco3), calcite and aragonite, are common, and
-
dolomite, a calcium-magnesium carbonate, (CaMg(C03)2) is also

common. Phosphate minerals are present in numerous samples. The

type of phosphate abundant in sediments from the Hawthorn Group in

the area is carbonate-fluorapatite, (Calo(PO4)6(F, OH, CO3)2,

commonly known as francolite (Cathcart, 1989). This mineral is a

form of apatite in which fluorine and carbonate ions partially

substitute for hydroxyl groups.

CONCLUSIONS

This project has resulted in the addition of over 180

additional lithologic descriptions to the computer data bases of

the FGS and the District. The cores drilled provide much needed

"anchor points" for stratigraphic and hydrogeologic projects and

fill critical gaps in the geologic data base. These sample sets

will be utilized in future studies, providing an ongoing benefit.

The Hendry County cores drilled for this project are the only cores

in Hendry County at the present time. Additional core drilling

projects are needed in this and other portions of the District to

fill the gaps in the geologic data base and provide a better

understanding of the geohydrologic framework of southern Florida.
