Abstract

The accompanying 1:100,000 scale geologic map (Open-File Map Series 98) shows the
areal distribution of bedrock and surficial geologic units for the eastern half of the Perry, Florida
30 x 60 minute quadrangle. The map was constructed using a combination of field mapping at
1:24,000 scale, compilation of data from existing maps (various scales), core and cuttings
analyses and descriptions, and analyses of various Geographic Information System (GIS) data
sources. The resulting data was compiled in ESRI's ArcGIS ArcMap 9.1 for publication as part
of the Florida Geological Survey Open-File Map Series (O.F.M.S.). Map units in the area range
in age from the Eocene Ocala Limestone to undifferentiated Quaternary sediments. Important
resources in the area include groundwater, springs, sand, limestone, and dolostone. Numerous
springs, sinking streams (swallets), and other karst features are present in the study area.
Understanding of geologic units, karst, springs and their interactions within the map area aids
land planners, environmental professionals, and citizens in making land-use decisions such as
designing new construction projects, siting new water supply wells, locating sources of mineable
resources for aggregate supply, and protection of springs and water quality.

Keywords: Florida, geologic map, environmental geology, geomorphology, springs,
swallets, Floridan aquifer system.

Introduction

This report is designed to accompany Open-File Map Series (O.F.M.S.) 98. O.F.M.S. 98-
01 depicts the near-surface geology of the eastern half of the Perry 30 x 60 minute quadrangle.
O.F.M.S. 98-02 depicts six geologic cross sections, as well as a correlative stratigraphic chart for
the lithologic units for the study area. O.F.M.S. 98-03 shows a geomorphology map, a digital
elevation model (DEM), locations of known springs, sinkholes and swallets, and photographs of
selected outcrops within the study area.
The study area lies east of Perry and west of Live Oak, Florida and includes portions of
Hamilton, Lafayette, Madison, Suwannee, and Taylor Counties (Figure 1). It lies west of the
Lake City 30 x 60 minute quadrangle, part of which was mapped under a grant from the U.S.G.S.
STATEMAP program (Green et al. 2006). A regionally important river, the Suwannee River,
bisects the map area, and much of the area serves as recharge to the Floridan aquifer system, the
primary source of drinking water in the region.
An objective for this report is to provide basic geologic information for the
accompanying geologic map (O.F.M.S. 98-01), cross sections (O.F.M.S. 98-02) and
geomorphology (O.F.M.S. 98-03). Information provided by this report and these maps is
intended for a diverse audience comprising professionals in geology, hydrology, engineering,
environmental and urban planning, and laypersons, all of whom have varying levels of geologic
knowledge. The map can help users identify and interpret geologic features which impact
activities related to groundwater quality and quantity, location of mineral resources, land-use
planning, and designing construction projects. Applied uses of the map and data in this report
include: 1) identifying potential new mineral resources, 2) characterizing aquifer recharge
potential and confinement, 3) aiding in water-management decisions on groundwater flow and

usage, 4) providing information on aquifer vulnerability to potential pollution, 5) ecosystem,
wetlands, and environmental characterization, and 6) recreational uses.

Methods

The study consisted of 1) reviewing and compiling existing geologic literature and data,
2) mapping geologic units in the field at 1:24,000 scale using standard techniques, 3) core and
cuttings analyses of existing samples, 4) new core drilling, 5) collecting and describing of
outcrop samples, and 6) preparing a geologic map, geological cross-sections, and geomorphic
map of the area. Field work was performed during the spring and summer of 2007 and consisted
of sampling and describing numerous outcrops, river and pit exposures. Seventy-eight new
samples of geologic material were added to the FGS surface-sample archives (M-Series), four
new cores were drilled, and numerous additional outcrops were examined during this project. All
data, including data from over 400 wells, were compiled and analyzed by the authors and the
map and accompanying plates were developed in ESRI's ArcGIS ArcMap 9.1 for publication as
part of the Florida Geological Survey Open-File Map Series.
The study area is blanketed by a veneer of Quaternary sediments and soils. For this
reason, and in keeping with geologic mapping practices developed by Scott et al. (2001), the
authors have adopted the policy of mapping the first named geologic unit within 20 feet (6.1
meters) of the surface. If undifferentiated Quaternary (Qu) sediments attain a thickness greater
than 20 feet (6.1 meters), then they appear as the mapped unit. If these undifferentiated
sediments are less than 20 feet (6.1 meters) thick, then the underlying stratigraphic unit appears
on the map.
The region is generally vegetated and public access is hindered by the presence of
numerous farms and private land-owners. Fieldwork access was typically limited to public roads,
State-owned lands, and Suwannee River Water Management District-owned lands.

Previous Work

The current study builds on many previous geologic investigations in and around the
present map area. A statewide geologic map (Scott, et al., 2001) was published by the FGS in
digital format and provided much of the base-map material. Preliminary county geologic maps
have been published for Hamilton (Scott, 1993), Lafayette (Campbell, 1993c), Madison
(Campbell, 1993a), Suwannee (Rupert et al. 1993), and Taylor (Campbell, 1993b) Counties at
scales of 1:126,720. It is important to point out, however, that each of these Open-File Map
Series geologic maps were constructed in an average time-frame of two weeks utilizing selected
in-house geologic data with little to no extra field work. Although these maps provided an
excellent starting point for the detailed geologic mapping undertaken for this project, significant
refinement of the geologic maps was possible as a result of this project. This study also benefited
from the work performed for geologic mapping in the western portion of the Lake City 30 x 60
minute quadrangle (Green et al. 2006). Many of the field relationships and stratigraphic
problems were worked out during that project and data gathered during the project proved
invaluable in the completion of this endeavor.

Geologic Summary

The near surface geology of the eastern portion of the U.S.G.S. 1:100,000 scale Perry
quadrangle is composed of a complex mixture of Eocene to Holocene carbonate and siliciclastic
sediments. A combination of factors, including fluvio-deltaic deposition, marine deposition,
dissolution of underlying carbonates, erosion of sediments as a result of eustatic changes in sea
level, and structural features, have influenced the geology of the study area.
Much of the eastern portion of the Perry quadrangle is located within the Suwannee,
Alapaha, Withlacoochee, and Econfina River basins (Figure 2). In this area, the Suwannee River
and its tributaries contain numerous documented springs, including six first magnitude springs
and 53 lesser magnitude springs. A first magnitude spring is defined as having a minimum
average flow of 100 cubic feet per second, or 64.6 million gallons per day. Many of these springs
have evidenced significant increases in pollutants in the last few decades, particularly nitrate
(Scott, et al. 2002). Detailed geologic mapping of lithostratigraphic units in this area provides
critical data needed to help in future assessments of the vulnerability of the aquifer systems and
these springs to contamination. The recharge areas for many of these springs are believed to be
located in and around the current study area. Understanding the surficial geology of the map
area is a key factor in developing management and protection plans, not only for the springs, but
for the unconfined portions of the Floridan aquifer system (FAS).

Structure

Several structural variables have affected the geology of the region. The Peninsular Arch,
(Figure 3) a structurally high area which affected deposition from the Cretaceous to the early
Cenozoic, is the dominant subsurface feature in the Florida peninsula (Applin, 1951; Puri and
Vernon, 1964; Williams et al. 1977; Schmidt, 1984; Miller, 1986; Scott, 1997).
The axis of the Peninsular Arch extends from southeastern Georgia to the vicinity of
Lake Okeechobee in southern Florida in a general northwest to southeast trend. The crest of the
arch passes beneath Alachua County south and east of the study area and is highest in Union and
Baker Counties east of the study area. The arch was a topographic high during most of the
Cretaceous Period and had Upper Cretaceous sediments deposited over it (Applin, 1951). It
formed a relatively stable base for Eocene carbonate deposition except during times of periodic
land emergence due to lowered sea levels (Williams et al. 1977). The arch did not affect
Neogene to Holocene sediment deposition (Williams et al. 1977; Scott, 1997).
The Ocala Platform is the most prominent structure affecting the near surface
depositional and post-depositional environments within the map area. Hopkins (1920) originally
named this feature the Ocala Uplift. Vernon (1951) described the Ocala Uplift as a gentle flexure
developed in Tertiary sediments with a northwest-southeast trending crest. Because there is
continuing uncertainty about the origin of this feature, Scott (1988) used the term Ocala
Platform, rather than Ocala Uplift or Ocala Arch, since it does not have a structural connotation.
The Ocala Platform exerted its influence on Neogene sediment deposition, and Miocene
sediments of the Hawthorn Group are thought to have been deposited across the platform (Scott,
1981a; Scott, 1988). Post-Miocene erosion, however, has removed sediments of the Hawthorn

Group from much of the crest of the Ocala Platform, exposing Eocene carbonates (Cooke, 1945;
Espenshade and Spencer, 1963; Brooks, 1966; and Scott, 1981b).

This is evident in the southern portion of the map area. Undifferentiated sediments have
subsequently been deposited on the exposed Oligocene and Eocene carbonates. These consist of
residual clays, sands, and aeolian sands deposited during the Pliocene to Holocene (Scott, 1997).

Vernon (1951), utilizing aerial photographs, first mapped fracture patterns throughout
northern peninsular Florida. Regionally, these fractures generally trend parallel to the axis of the
Ocala Platform in a northwest-southeast orientation. A secondary system of fractures intersects
these primary fractures at high angles in a northeast-southwest trend (Vernon, 1951). Orientation
of stream meanders along the Suwannee River suggests that these fracture patterns may be a
controlling factor in stream location (Colton, 1978).
Several relict Neogene coastal terraces, which developed as a result of fluctuating sea
levels, have been documented in the study area. Healy (1975) recognized three marine terraces
within the study area (Figure 4): the Wicomico terrace at elevations of 70 to 100 feet (21.3 to
30.5 meters) above mean sea level (MSL), the Sunderland/Okefenokee terrace at elevations
between 100 and 170 feet (30.5 and 51.8 meters) above MSL, and the Coharie terrace at
elevations between 170 and 215 feet (51.8 and 70.5 meters). The elevations between 150 and 170
feet (45.7 and 51.8 meters) above MSL were referred to as the Okefenokee Terrace by MacNeil
(1950) and Alt and Brooks (1965). Detailed discussions and correlations of these marine terraces
and relict shorelines have been attempted by many authors, including Matson and Sanford
(1913), Cooke (1931, 1939), Flint (1940, 1971), MacNeil (1950), Alt and Brooks (1965), Pirkle
et al. (1970), and Healy (1975).

Geomorphology
Geomorphic Districts

According to Scott (2005), the study area contains part of three geomorphic provinces -
the Ocala Karst District, the Okefenokee Basin District, and the Tifton Upland District (see
Figure 2, O.F.M.S. 98-03). Within the map area, these districts have been further subdivided
topographically into five regional physiographic units: the Alachua Karst Hills, the Perry
Karst/San Pedro Bay, and the Branford Karst Plain (Ocala Karst District), the Northern
Okefenokee Basin (Okefenokee Basin District), and the Madison Hills (Tifton Upland District)
(see Figure 3, O.F.M.S. 98-03).

Ocala Karst District

The majority of the current study area is located within White's (1970) Gulf Coastal
Lowlands. Scott (2005) refers to this area as the Ocala Karst District. Within Florida, the Ocala
Karst District encompasses a broad area from Wakulla County in the panhandle of Florida, south
to Hillsborough and Pinellas Counties in the west-central peninsula and inland to nearly the
center of the peninsula. Elevations within the district range from sea level along the coast to in
excess of 300 feet (91.4 meters) above MSL on the Brooksville Ridge (O.F.M.S. 98-03, Figure 3).
Within the study area, elevations range from 45 feet (13.7 meters) in the southwestern comer of the
study area to 170 feet (56.0 meters) along the eastern edge of the map area (O.F.M.S. 98-03, Figure
1).
Carbonate sediments, ranging from the Middle Eocene Avon Park Formation to the
Lower Oligocene Suwannee Limestone, lie at or near the land surface within this district. The
Ocala Karst District is dominated by dissolution sinkholes and shallow bowl-shaped depressions,
producing a rolling topography. Generally, a variably permeable siliciclastic cover allows
downward percolating groundwater to slowly dissolve the underlying limestone, leading to
cover-collapse sinkholes and cover-subsidence features. Cover-collapse sinkholes form rather

FLORIDA GEOLOGICAL SURVEY

abruptly from the structural failure of an underlying cavern roof An excellent example of this is
Devil's Mill Hopper, located in Alachua County southeast of the present study area (Evans, et al.
2004).
Cover subsidence features generally occur in areas where overlying siliciclastics are
thicker and sediments sag as carbonates dissolve underneath. Typically, areas such as these have
only a few shallow sinks formed by the downward movement of the siliciclastic overburden
filling voids created by slow dissolution of underlying carbonates. Springs, sinking and resurgent
streams, and caverns commonly occur within the Ocala Karst District.

Alachua Karst Hills

The Alachua Karst Hills, present along the eastern edge of the study area, are part of
White's (1970) Northern Highlands. This physiographic unit is well drained and formed in
response to karstification of uplands covered by Hawthorn Group and undifferentiated
sediments. The karst hills are part of an erosional scarp retreat being formed as the Hawthorn
Group and younger sediments are eroded and karstified. This scarp is part of the extensive Cody
Scarp of Puri and Vernon (1964).
Regionally, the Alachua Karst Hills extend from northern Suwannee County to central
Alachua County (O.F.M.S. 98-03, Figure 3). Elevations range from approximately 100 feet (30.5
meters) to in excess of 200 feet (61 meters) above MSL. In the study area, the Alachua Karst
Hills are only present within central Suwannee County along the eastern boundary of the mapped
area, where elevations range from approximately 70 feet (21.3 meters) to 170 feet (51.8 meters)
above MSL (O.F.M.S. 98-03, Figure 3).

Branford Karst Plain

The Branford Karst Plain, which covers much of the eastern two-thirds of the map area,
occupies the Suwannee River valley, the Alapaha River valley, and the Withlacoochee River
valley (O.F.M.S. 98-03, Figure 3). Regionally, the plain extends south to the Santa Fe River on
the Gilchrist County line (Scott, 2005). Elevations in the karst plain range from less than 15 feet
(4.6 meters) above MSL along the Suwannee River to more than 140 feet (42.7 meters) above
MSL. Within the study area, elevations of the Branford Karst Plain range from 20 feet (6.1
meters) along the Suwannee River valley in the southeastern corner of the map area to 140 feet
(42.7 meters) above MSL in the northeastern portion of the map area (O.F.M.S. 98-03, Figure 1).
The Lower Oligocene Suwannee Limestone occurs in the northern half of the Branford
Karst Plain and crops out within the Withlacoochee and Alapaha River valleys and the northern
portion of the Suwannee River valley within the map area, while the Upper Eocene Ocala
Limestone is near the surface in the southern part of the Branford Karst Plain. Silicified "float"
boulders (remnants of the Lower Oligocene Suwannee Limestone and the Upper Eocene Ocala
Limestone) are common in the southeastern quadrant of the map area.
Drainage within the Branford Karst Plain is primarily through karst features with
relatively few surface streams. Closed topographic depressions (CTDs; Arthur et al. 2007) are
numerous throughout the karst plain, particularly east of the Suwannee River (O.F.M.S. 98-03,
Figure 1).

Perry Karst/San Pedro Bay

Regionally, the Perry Karst/San Pedro Bay complex extends from Madison County
southward to the Gulf of Mexico in Dixie County (O.F.M.S. 98-03, Figure 3). The Perry Karst is
the transition zone between the Woodville Karst Plain to the west and San Pedro Bay. Elevations
within this area range from less than 5 feet (1.5 meters) to in excess of 100 feet (30.5 meters) above
MSL. The elevations in San Pedro Bay are generally higher than in the Perry Karst area or the
Branford Karst Plain. Elevations decline to the south toward the Gulf coast. The Perry Karst area is
poorly to moderately drained while San Pedro Bay is extremely poorly drained. Copeland (2005)
provides an excellent discussion of the San Pedro Bay, its origin and surrounding areas. The Perry

FLORIDA GEOLOGICAL SURVEY

Karst/San Pedro Bay complex occupies much of the western and southwestern parts of the study
area. Within the map area, elevations of the Perry Karst/San Pedro Bay range from 45 feet (13.7
meters) to over 100 feet (30.5 meters) above MSL (O.F.M.S. 98-03, Figure 1).
The Suwannee Limestone underlies much of the Perry Karst/San Pedro Bay, although it is
absent under the central-southern and southeastern portions of the unit. In the San Pedro Bay, a clay
layer up to five feet (1.5 meters) thick overlies the limestone, providing confinement to the FAS
(Copeland, 1982). Plio-Pleistocene sediments cover the entire area, and the unit is poorly to very
poorly drained. Recharge to the FAS is low to moderate, while recharge to the FAS may be
moderate to high along the transition between the Perry Karst/San Pedro Bay and the Branford
Karst Plain (Copeland, 2005).

Okefenokee Basin District

The Okefenokee Basin District is recognized based on topography, drainage characteristics
and the general lack of karst features. East of the present study area, the Lake City Ridge subdivides
the district into northern and southern basins (Scott, 2005). In the northern Okefenokee Basin, the
hills are essentially absent and the entire area is poorly drained and flat. Hills are common and the
area is better drained in the Southern Okefenokee Basin. The basin extends into Florida from
Georgia and is recognized from Baker, Hamilton, and Columbia Counties on the north, southwards
to northern Alachua County (O.F.M.S 98-03, Figure 3). Where the Okefenokee Basin District
makes the transition to the Ocala Karst District, the land becomes well drained and has more relief.
Miocene Hawthorn Group (Th) sediments to Plio-Pleistocene siliciclastics underlie the
district. The Statenville Formation of the Hawthorn Group (Ths) occurs at or near the surface in the
western portion of the district, while Undifferentiated Plio-Pleistocene siliciclastics (TQu) underlie
the eastern portion of the district.

Northern Okefenokee Basin

The Northern Okefenokee Basin lies to the north of the Lake City Ridge, the Alachua Karst
Hills and the Branford Karst Plain and east of the Madison Hills (O.F.M.S. 98-03, Figure 3).
Northeast of the study area, the Okefenokee Swamp occupies much of the northern portion of the
Okefenokee Basin District from Georgia into Florida. The northern portion of the basin is very flat
with few hills. Hills become more common towards the western and eastern boundaries of the area.
Plio-Pleistocene siliciclastics underlie much of the northern Okefenokee Basin but are
poorly drained due to the near-surface presence of the Hawthorn Group clayey sediments and low
relief. The Statenville Formation of the Hawthorn Group (Ths) is at or near the surface in the
western part of the basin. Karst features, which are uncommon throughout most of the basin, occur
primarily in the transition zone with the Ocala Karst District where the Hawthorn Group is thin and
breached by sinkholes.
Elevations vary within the basin from approximately 100 feet (30.5 meters) to more than
190 feet (57.9 meters) above MSL (Scott, 2005). Where the Suwannee River occurs within the
district east of the study area, elevations along the river may be less than 50 feet (15.2 meters).
Within the map area, elevations range from 60 feet (18.3 meters) near the Suwannee River to 160
feet (48.8 meters) on some of the hilltops.

OPEN FILE REPORT NO. 91

Tifton Upland District

In northern Florida, the Tifton Upland District (Scott, 2005) encompasses the area referred
to as the Tallahassee Hills by White (1970). The uplands extend from the Apalachicola River
eastward to central Hamilton County at the Alapaha River (O.F.M.S. 98-03, Figure 2). The Tifton
Upland District's topography is characterized by broad, undulating hills with a well developed
dendritic drainage pattern.
The Tifton Upland District is present in the northwestern and northern portion of the map
area. Elevations in the district, which range from 35 feet (10.7 meters) above MSL in the major
stream and river valleys and in the swamps of the eastern portion of the district up to 300 feet (91.4
meters) MSL on the hilltops, decrease toward the southern limit of the district.

Madison Hills

Within the study area, Scott (2005) delineated one physiographic unit within the Tifton
Upland District: the Madison Hills. Regionally, the Madison Hills extend from the eastern end of
the Tallahassee Hills in central Jefferson County, eastward to eastern Madison County on the west
side of the Withlacoochee River (O.F.M.S. 98-03, Figure 3). The elevation of the Madison Hills
ranges from 70 feet (21.3 meters) in the valleys between the Withlacoochee and Alapaha rivers to
near 200 feet (61 meters) above MSL on some hill tops.
The Madison Hills are present in the northwestern portion of the map area, while a small
area (separated from the main body of this zone by the Withlacoochee River Valley) is present in
Hamilton County. Elevations within the map area for the Madison Hills range from 70 feet (21.3
meters) above MSL to 200 feet (61 meters) above MSL on some hilltops (O.F.M.S. 98-03, Figure
1).
The valleys within the Madison Hills are broad and poorly drained. The Miccosukee
Formation (Tmc) forms the higher areas while the Hawthorn Group sediments underlie the lower
portions of the landscape. Karst features occur in the eastern part of the district where the
Suwannee Limestone lies near the land surface.

Lithostratigraphic Units

Tertiary System

Eocene Series
Middle Eocene

The Middle Eocene Avon Park Formation (Tap), first described by Applin and Applin
(1944), is the oldest unit investigated in the present study area. The unit, which only occurs in the
subsurface in the study area, consists of cream to light-brown to tan, poorly indurated to well-
indurated, variably fossiliferous limestone (grainstone to wackestone, with rare mudstone). The
limestones are interbedded with tan to brown, very poorly indurated to well indurated, very fine
to medium crystalline, fossiliferous (molds and casts), vuggy dolostones. Fossils present in the
unit include molluscs, foraminifera, echinoids, algae and carbonized plant remains.

FLORIDA GEOLOGICAL SURVEY

The Avon Park Formation was only encountered in a few wells in the study area. The top
of the Avon Park ranges from 307 feet (93.6 meters) below MSL in W-2548 to 164 feet (50
meters) below MSL in W-4497 (cross-section D-D'; OFMS 98-02). No wells utilized for cross-
sections penetrated the entire section of the Avon Park Formation. The Avon Park Formation
forms part of the FAS (Southeastern Geological Society, 1986).

Eocene Series
Upper Eocene

The Upper Eocene Ocala Limestone (To), first described by Dall and Harris (1892) is a
biogenic marine limestone comprised largely of foraminifera, molluscs, echinoids and
bryozoans. Based on lithologic differences it can be informally subdivided into an upper and
lower unit (Scott, 1991a). This subdivision, while often apparent in cores and quarries, is
difficult to ascertain in cuttings. As a consequence of this, the geologic cross sections do not
break out the upper and lower Ocala Limestone.
The upper unit is typically a white to cream, fine- to coarse-grained, poorly- to well-
indurated, poorly sorted, very fossiliferous limestone (wackestone, packstone, and grainstone).
Fossils commonly include large foraminifers, bryozoans, mollusks, and a rich diversity of
echinoids. The lower unit is typically a white to cream, fine- to medium-grained, poorly- to
moderately- indurated limestone (grainstone to packstone). The unit may be partially
dolomitized. Fossils include foraminifera (such as Lepidocyclina sp., Heterostegina ocalana, and
miliolids), bryozoans, algae, mollusks, echinoids, and crabs.
Portions of the upper Ocala Limestone have been locally replaced by silica and upon
erosion large boulders may remain as residual float. The most likely source of silica is from
weathering of the Hawthorn Group sediments (Williams et al. 1977; Scott, 1988). There are
several processes that have occurred, or are occurring, in the Hawthorn Group which release
silica in solution and provide a source for silica in the replacement of carbonate rocks (Altshuler
et al. 1963; Mitchell, 1965; and Assefa, 1969). The occurrence of this float throughout the
southern portion of the study area is an indication that the Hawthorn Group once covered much
more of the study area and has been subsequently removed by erosion and weathering (O.F.M.S.
98-01).
The top of the Ocala Limestone, which is often karstified, ranges from 60 feet (18.2
meters) above MSL in W-187 (cross sections B-B' and E-E'; OFMS 98-02) to 109 feet (33.2
meters) below MSL in W-2549 (cross sections A-A', D-D', and E-E'; OFMS 98-02). Only a few
wells penetrated the entire thickness of the Ocala Limestone in the study area. In these wells, the
thickness of the Ocala Limestone ranges from 177 feet (53.9 meters) in W-2549 (cross-sections
A-A', D-D' and E-E'; OFMS 98-02) to 220 feet (67.1 meters) in W-2550 (cross section E-E';
OFMS 98-02). The Ocala Limestone is unconformably overlain by the Suwannee Limestone
(Ts) throughout much of the study area and by undifferentiated Quaternary sediments (Qu) in the
southern and southeastern portions of the study area. The Ocala Limestone forms part of the
Floridan aquifer system (Southeastern Geological Society, 1986).

OPEN FILE REPORT NO. 91

Oligocene Series
Lower Oligocene

The Lower Oligocene Suwannee Limestone (Ts), named by Cooke and Mansfield (1936)
for exposures of limestone along the Suwannee River from White Springs to Ellaville,
unconformably overlies the Ocala Limestone throughout most of the study area. The Suwannee
Limestone is primarily a white to cream, poorly to well indurated packstone to grainstone
comprised of miliolid tests, foraminifera, pelecypods, gastropods and echinoids. The echinoid
Rhyncholampas gouldii, an index fossil for the Suwannee Limestone, is commonly seen in
outcrops along the Suwannee River. The lithology is variably recrystallized and may range from
poorly indurated, friable limestone to well indurated limestone cemented by calcite spar.
Silicified residual boulders of the Suwannee Limestone ("float") are commonly found in the
south-central to southeastern portion of the study area, indicating that it once covered much of
the southern portion of the map area (O.F.M.S. 98-01).
The top of the Suwannee Limestone ranges from 5 feet (1.5 meters) above MSL in W-
12516 (cross section A-A'; OFMS 98-02) to 112 feet (34.1 meters) above MSL in W-15888
(cross section D-D'; OFMS 98-02). The Suwannee Limestone ranges in thickness from
approximately 5 feet (1.5 meters) in W-18768 (cross section B-B'; OFMS 98-02) to
approximately 160 feet (48.8 meters) in W-18767 (cross section A-A'; OFMS 98-02).
The unit is unconformably overlain by sediments of the Miocene Statenville Formation
(Ths; Hawthorn Group) in the northeastern portion of the map area, sediments of the Miocene
Torreya Formation (Tht; Hawthorn Group) in the northwestern portion of the study area, and
undifferentiated Quaternary sediments (Qu) throughout the remainder of the study area.
Evidence from cuttings and field data indicates that isolated remnants of the Suwannee
Limestone may occur throughout the southeastern portion of the map area (see W-358 and W-
13471 on cross section E-E'; OFMS 98-02). The Suwannee Limestone forms part of the Floridan
aquifer system (Southeastern Geological Society, 1986).

Miocene Series

Hawthorn Group (Th) sediments are encountered throughout much of the northern one-
third of the study area, where they unconformably overlie the Suwannee Limestone (O.F.M.S.
98-01). Sediments of the Hawthorn Group are thought to have been deposited onto the platform
throughout the area, but Post-Miocene erosion removed sediments from the crest of the Ocala
Platform exposing the Eocene carbonates in the southern portion of the map area (Cooke, 1945;
Espenshade and Spencer, 1963; Brooks, 1966; and Scott, 1981b). Fossils in the Hawthorn Group
are sparse but may include vertebrate remains, corals, and mollusks. Williams et al. (1977) report
that the most commonly found fossils are oysters and coral heads. Silicified coral heads were
observed in the Suwannee, Withlacoochee, and Alapaha Rivers during field work. Within the
map area, the Miocene Hawthorn Group (Th) is composed of the Lower Miocene Torreya
Formation (Tht) and the Middle Miocene Statenville Formation (Ths). The Torreya Formation is
present west of the Withlacoochee River, while the Statenville Formation (Ths) occurs east of
the Withlacoochee River (O.F.M.S. 98-01).

FLORIDA GEOLOGICAL SURVEY

Lower Miocene

The Lower Miocene Torreya Formation of the Hawthorn Group (Tht) is typically a
siliciclastic unit with increasing amounts of carbonate in the lower portion of the unit. The
majority of the outcrops of the Torreya Formation expose the siliciclastic part of the unit which
varies from white to light olive gray unconsolidated to poorly indurated slightly clayey sands to
light gray to bluish gray, poorly consolidated silty clay often containing a variable but minor
component of carbonate (calcareous or dolomitic). Phosphate grains, while a common but minor
lithologic component of the unit are often absent (Scott, 1988).
The carbonate sediments of the Torreya Formation are white to light olive gray, poorly
indurated, variably sandy and clayey limestones. The limestone (mudstone and wackestone)
often contains molds and casts of mollusks. The Torreya Formation overlies the Floridan aquifer
system and forms part of the intermediate aquifer system/intermediate confining unit (IAS/ICU)
(Southeastern Geological Society, 1986).
The top of the Torreya Formation ranges from 84 feet (25.6 meters) above MSL in W-
2549 (cross sections A-A', D-D', and E-E'; OFMS 98-02) to 144 feet (43.9 meters) above MSL
in W-15888 (cross section D-D'; OFMS 98-02). In wells utilized for cross sections, the unit
ranges from 10 feet (3 meters) thick in W-704 (cross section E-E'; OFMS 98-02) to 80 feet (24.4
meters) thick in W-12516 (cross section A-A'; OFMS 98-02).

Middle Miocene

The Middle Miocene Statenville Formation of the Hawthorn Group (Ths) occurs within
limited areas of the northeastern portion of the map area along the northeastern flank of the
Ocala Platform (Scott, 2001b). The Statenville Formation consists of poorly to moderately
indurated, interbedded quartz sands, clays and dolostones. Phosphate grains are common to
abundant in the unit. The unit is lithologically variable and beds may pinch out and interfinger
both laterally and vertically. Outcrops of the Statenville Formation in the study area are
characteristically thin-bedded and often cross-bedded, generally consisting of thinly interbedded
layers of dolostone and clay alternating with beds of sand. The Statenville Formation forms part
of the IAS/ICU (Southeastern Geological Society, 1986).
The top of the Statenville Formation ranges from 60 feet (18.3 meters) above MSL along
parts of the Suwannee River to 160 feet (48.8 meters) above MSL in hills north of Live Oak
(cross section F-F'; OFMS 98-03). The Statenville Formation ranges up to 100 feet (30.5 meters)
in thickness in the northeastern portion of the map area (cross section F-F'; OFMS 98-03).

Tertiary-Quaternary Systems

Pliocene Series

The Pliocene Miccosukee Formation (Tmc), named by Hendry and Yon (1967), is a
prodeltaic siliciclastic unit composed of grayish-orange to grayish-red, mottled, poorly- to
moderately indurated, interbedded clay, sand and gravel of variable coarseness and admixtures.
The unit has limited distribution in the eastern panhandle of Florida and occurs from central
Gadsden County (west of the study area) to eastern Madison County (Scott et al. 2001).

OPEN FILE REPORT NO. 91

The top of the unit, present within a limited area in the northwestern comer of the map
area, ranges from approximately 100 feet (30.5 meters) above MSL to approximately 200 feet
(61 meters) above MSL (cross sections A-A', D-D' and E-E'; OFMS 98-02). The Miccosukee
Formation ranges from a few feet to approximately 100 feet (30.5 meters) in thickness in this
area. The unit is relatively impermeable due to its high clay content, but is considered to be part
of the SAS (Southeastern Geological Society, 1986).

Pleistocene Series

Undifferentiated Quaternary sediments (Qu) lie unconformably on either the Eocene
Ocala Limestone (To), the Oligocene Suwannee Limestone (Ts), the Miocene Torreya Formation
(Tht), or the Miocene Statenville Formation (Ths) throughout much of the study area. These
sediments, which generally consist of sandy clays and clayey sands, often include weathered and
silicified boulders of the Ocala Limestone and Suwannee Limestone ("float"). The
undifferentiated Quaternary sediments (Qu) are part of the surficial aquifer system (SAS;
Southeastern Geological Society, 1986).
Sediments mapped as Quaternary Beach Ridges and Dunes (Qbd) exhibit discernable
beach ridges and dune features. These sediments consist of unconsolidated light gray to tan fine
to medium quartz sand with variable percentages of organic material. They are only present in a
small area in the extreme southeastern portion of the map area. The Quaternary Beach Ridges
and Dunes (Qbd) sediments are part of the SAS.

Hydrogeology

The hydrogeology of the map area consists of (in ascending order) the Floridan aquifer
system (FAS), the intermediate aquifer system/intermediate confining unit (IAS/ICU), and the
surficial aquifer system (SAS) (Southeastern Geological Society, 1986). The FAS, which is the
primary source of drinking water in the region, is generally comprised of carbonate units of the
Avon Park Formation, the Ocala Limestone, and the Suwannee Limestone. The sands, silts, and
clays of the Hawthorn Group comprise the intermediate aquifer system/intermediate confining
unit. The surficial aquifer system is comprised of the Miccosukee Formation and
undifferentiated Quaternary sediments.
Where siliciclastic sediments of the Hawthorn Group and Miccosukee Formation are
thick, they provide confinement for the Floridan aquifer system, but where the siliciclastic
sediments of the Hawthorn Group and younger units are thin or missing, karst features often
occur. "Swallets" (stream-to-sink features) are of particular concern to geoscientists and
hydrogeologists in the area. Numerous swallets occur along the western edge of the Alachua
Karst Hills and provide avenues for direct recharge to the FAS by surface water and runoff from
agricultural and urban areas (O.F.M.S. 98-03, Figure 1).

Derivative Products

Several derivative products will come from this project. During the mapping project, data
from several hundred wells (Table 1) were analyzed. Formation picks, made on all available
wells, will allow for the creation of a structure contour map of the top of rock in the study area,
along with an isopach map of overburden for the area. Several of the authors of this report are

FLORIDA GEOLOGICAL SURVEY

working on an additional publication, which is beyond the scope of the original project, which
will depict these maps. Additional derivative data that is anticipated to come from this mapping
effort includes an aquifer vulnerability assessment map. Data derived from prior STATEMAP
products has often been used to augment other FGS and FAVA projects in the state (Arthur et al.
2007; Baker et al. 2007).

*NOTE: Suwannee River Water Management District (SRWMD) Archived ID # is the well's
township, range, and section location. The format is as follows: + or indicates township north
(+) versus south (-); there is no need to include an east / west indicator for the range, as the entire
SRWMD is east of the Prime Meridian. Following the +/- are 6 digits representing the township,
range, and section (TTRRSS), and finally a 3 digit unique identifier assigned consecutively to
each well within a given section to differentiate wells with the same +/- and 6 digit number.

For example: -031224004 means Township 03 South, Range 12 East, Section 24, unique well
004.
