PREFACE
The lower sediments of the Upper Cretaceous section of northern peninsular Floridacoiisist predominantly of sands and shales. These sediments are present over most of southern Georgia and peninsular Florida. The sands have good porosities and probably would form good oil reservoirs; Ihe shales are dark and appear to have high organic content that could have made them sources of petroleum. The penetration by wells in the area is considered to be insufficient to condemn the land area as a petroleum prospect, and the adjacent ocean bottoms hold even greater promise.
The report presents a number of geologic cross sections and maps upon which broad interpretations of correlations, stratigraphy and regional structures are based. The Upper Cretaceous clastic section of the Atkinson Formation is shown to pinch-out upon the underlying Lower Cretaceous sediments elevated along the Peninsular arch. Younger, less permeable sediments overlap the Upper Cretaceous clastics.
A basal sand in the Austin interval, which the Applins (1967, p. 19) referred to as the "chalky sandstone facies in the lower part of the unit of Austin age," is described and named the LaCrosse Sandstone.

GEOLOGY OF THE UPPER CRETACEOUS CLASTIC SECTION
NORTHERN PENINSULAR FLORIDA

INTRODUCTION
The report area, figure 1, encompasses 29 counties and approximately 20,000 square miles in northern peninsular Florida, and about 15,000 square miles in southern Georgia. Georgia is included to show the relationship of the geology in adjoining area to that of northern Florida.
There -is relatively little relief in the area, and the maximum elevation is only about 175 feet. The area is traversed by many streams. It is bounded on the west by the Gulf of Mexico, the western boundary of Jefferson" County, and generally longitude 84 degrees west; on the east by the Atlantic Ocean; and on the north by the approximate northern limit of the shallow-water marine facies of the Atkinson Formation (the Applins, 1947, map No. 5). To the south the study area extends to the southern boundaries of Pasco, Sumter, Lake, and Orange counties; thus the main part of the Peninsular arch is included within the geologic setting.
PURPOSES OF REPORT AND METHOD OF STUDY
The primary purposes of this report are: 1) to describe a new formation for which the name the LaCrosse Sandstone is suggested, 2) to map, and briefly describe for the report area, the lithologic units of the Atkinson Formation, and the uppermost beds of the underlying Lower Cretaceous section.
In this study, lithologic and other geologic data were obtained by examining well cuttings, cores and electric logs from 78 selected wells. The locations and data on these wells are shown on the figures of this report, and in appendix 1, respectively.
ACKNOWLEDGEMENTS
The writer is indebted to personnel of the Bureau of Geology, Florida Department of Natural Resources, for stimulating discussions, data, review of the manuscript, proof of copy and preparation of illustrations.
UPPER CRETACEOUS (GULF) SERIES LA CROSSE SANDSTONE
The sandstone unit for which the name the La Crosse Sandstone is suggested was described by the Applins in 1967 in text (p. 19, including table 4), and by an isopach map (plate 4 B). The Southeastern Geological Society cross sections (1949) showed sand in the lower part of an undifferentiated section of Austin Age, and logs in the open file of the Bureau of Geology contain descriptions of this unit.

Sediments that are typical of the La Crosse Sandstone were penetrated by 14 wells. Also, a slightly less typical accumulation of the unit was recognized in two wells located east and west, respectively, and downgradient of the main body of the formation. These two tests are the Gulf, No. 1 Kie Vining well, in west central Columbia County, and the National Turpentine, No. 1 Fee well, in the southwestern corner of Baker County. In these wells the La Crosse Sandstone is pale yellowish brown to very pale orange in color, and it is more calcareous, as well as generally more uniformly fine-grained, than it was in the type well. Finally, a sandstone that is of very pale orange color, and much less calcareous than is the sandstone of the type well, was penetrated by the Sun, No. 1 Williams Brothers well in northern Gilchrist County and by the Sun, No. 1 Odom well in southeastern Suwannee County; this sand is assigned to the LaCrosse Sandstone.

Thickness and Extent
This unit, which the isopach map of figure 3 shows to have a maximum thickness of 273 feet, occurs in the central part of northern Florida, where it is concentrated high on the western flank of the Peninsular arch. The La Crosse Sandstone thins in all directions away from the center of deposition, and it is overlapped by younger sediments.
Overlying Rock
The rock overlying the La Crosse Sandstone is of Austin Age, and in the type well it is chalk, as it is in most wells in the report area; but in some wells this overlying rock is marl, sandy limestone, or very calcareous shale, as revealed by the stratigraphic-structural cross sections of figures 4, 5, and 6.
Underlying Rock
In the type well the rock underlying the La Crosse Sandstone is light brown, sandy shale which questionably belongs in the Atkinson Formation. In most other wells the underlying rock has been assigned to the Atkinson Formation, and it is typically a gray, calcareous, "poker-chip" shale, which is often micaceous.
Two tests located near the axis of the Peninsular arch found the La Crosse Sandstone underlain by Paleozoic rock. These wells are: Depth (and

The Applins (1967, p. 20) reported that a core of this unit from the National Turpentine, No. 1 Fee Well, located in southwestern Baker County, contained specimens of Pseudofrondicularia lanceola (Reuss) var. bidentata (Cushman) which, they state, has not been reported from beds older than Austin Age. The assignment of -the La Crosse Sandstone to an Austin Age is generally substantiated by electric log and sample correlations which indicate that the unit is the stratigraphic equivalent of a gray marl or chalk section of Austin Age. The stratigraphic-structural cross section C-C (fig. 6), however, shows that the lower part of the La Crosse Sandstone in the Gulf, No. 1 Kie Vining well is the stratigraphic equivalent of sediments of the Atkinson Formation in the Sun, No. 1 Tiis well which are included in the Eagle Ford microfaunal zone by the Southeastern Geological Society (1949, cross section D-D').

Source Rock
The La Crosse Sandstone is an isolated unit. It may have been derived from Paleozoic and perhaps Lower Cretaceous 'outcrops exposed during the time it was deposited, as indicated by figures 3 and 7. Possibly, also, transport of material from these older beds through a depositional interface (Krumbein and Sloss, 195, p. 5) may have contributed to the accumulation of the La Crosse Sandstone.
DISCUSSION
It will be noted in the correlation chart of figure 8 that the La Crosse Sandstone is the stratigraphic equivalent of either the entire interval of the Eutaw Formation, as depicted in the Alabama surface section, or the upper part of that formation, as shown on the subsurface section for Mississippi and Alabama. However, the La Crosse Sandstone is lithologically different from the Eutaw Formation, the approximate southeastern limit of which is in southwestern-Alabama (the Applins, 1947, map No. 1). Certainly the lithologic character of the La Crosse Sandstone differs from that of the Eutaw Formation in that this northern Florida unit is composed of uniformly fine quartz grains, and it is predominantly light tan to very pale orange in color, calcareous, soft, rarely fossiliferous, and almost entirely without shale associations in most wells. The Eutaw Formation, on the other hand, is described by Monroe, Conant and Eargle (1946, p. 207-210) as sandstone which is gray and reddish tan, cross-bedded, highly glauconitic, carbonaceous, macrofossiliferous, and with disseminated clay and clay laminae. Sharks teeth are present in the Eutaw Formation, especially in its upper (Tombigbee) member, and locally in a basal member.

The top of the La Crosse Sandstone is contoured on figure 9.

Florida
Paul L. Applin and Esther R. Applin (1947) named the Atkinson Formation, and showed it to be roughly the equivalent of the Tuscaloosa Group and McShan Formation of Alabama. As proposed by the Applins in 1947, the Atkinson Formation consisted of three members. The upper member,
"...(contains) three depositional facies ..which in down-dip wells merge vertically and laterally into each other. These are 1) a littoral or possibly nonmarine unfossiliferous facies characterized by red shales, poorly sorted sand, and some gravel; 2) A shallow-water marine facies composed chiefly of sand with lesser amounts of greenish-gray shale and containing fragments of molluscan shells; 3) a deeper water marine facies composed chiefly of dark-green flaky shale with some fine-grained sandstone, and containing, in addition to fragments of macrofossils, a microfauna which is closely similar to
that of the Eagle Ford shale of Texas."
The middle member,
"...was evidently deposited in a rather shallow-water marine environment and contains a sparse but diagnostic microfauna of arenaceous foraminifera that is related to the microfauna of the outcropping Woodbine formation of Texas.
Lithologically the member is composed chiefly of dark-gray to greenish-gray flaky shale and dark brownish-gray to black splintery shale with some irregular lenses of white speckled shale. The shale is usually micaceous (biotite and
muscovite), carbonaceous, silty and glauconitic." The lower member,
"...is generally an unfossiliferous littoral or nonmarine deposit...that gradually merges with an equivalent marine facies in which scattered lenses of shale contain arenaceous species common in the microfauna of the overlying middle
Atkinson."
The Southeastern Geological Society (1949) published four cross sections which included 16 northern Florida wells that were located in the area of the present report, and in which the Atkinson Formation was divided into the Eagle Ford and Woodbine microfaunal zones, rather than the three members designated by the Applins in 1947. Some of these zonal determinations were used in the present report.
Vernon (1951, fig. 16) followed the zonal divisions used by the Southeastern Geological Society, but separated the two zones into shale and sand units; five wells used in his report are included in this study.
Esther R. Applin (1955, p. 187), in order "To clarify the correlation of the Atkinson Formation of the subsurface in the Southeastern gulf region with the Eagle Ford and Woodbine formations of Texas," redefined the Atkinson Formations "to consist of two members, an upper member of Eagle Ford age as formerly used, and a lower member of Woodbine age consisting of the former lower and middle members."'
12 BUREAU OF GEOLOGY
The Applins (1965, plate 10) published a cross section which shows for several wells the depths from which diagnostic Woodbine fossils occurred in an oolitic limestone facies which they describe, and which occurs in the lower part of their lower member of the Atkinson Formation; they also show depths at which a Washita fossil was found in rock which underlies the Upper Cretaceous sequence. Four of the wells on this cross section are included in the present report area. Other figures presented by the Applins in their 1965 report which pertain to the present study area included 1) a structural cross section showing the top of the Atkinson Formation, and of the Lower Cretaceous section, in three wells (plate 9, cross section Y-Y), 2) a structural stratigraphic section depicting the Applins' lower member of the Atkinson Formation, and the Lower Cretaceous section, in two wells (plate 6, cross section V-V), and 3) a map showing the approximate areal distribution of the lithofacies of the basal part of the lower member of the Atkinson Formation (1965, fig. 45, p. 67).
Maher (1965, plates 2 and 8) published two cross sections that contained five wells located in the area of this study.
The Applins (1967, plate 7) published two cross sections showing 13 wells located in the area of the present report in which the Atkinson Formation was divided into an upper and lower member as redefined by Esther R. Applin (1955, p. 187). Also, the Applins' report (plate 3) presented maps showing the areal distribution of the various lithofacies within their upper and lower members, respectively, and the thicknesses of each of these members.
Georgia
Authors who have published on the stratigraphy of the southern Georgia area included in this report are: the Applins (1944; 1947; 1967), the Mesozoic Committee of the Southeastern Geological Society (1949), Hurst (1960), Herrick (1961), Hull (1962), Herrick and Vorhis (1963), and Maher (1965).
USAGE IN THIS REPORT
In the area of study the Atkinson Formation is composed essentially of shale, shaly sand, or shaly limestone in the upper part, and sand with minor shale stringers in the lower portion. Thus, on the basis of predominant rock character, the formation roughly divides into a shaly unit, and a basal sand unit, as shown on the correlation chart of figure 8.
Assignment of the upper sediments of the Atkinson Formation to an Eagle Ford Age, and the lower sediments to a Woodbine Age, was accomplished by the Southeastern Geological Society (1949)in 16 Florida wells, by Vernon (1951) in 5 wells, and by the Applins (1965;1967) in 6 and 13 wells, respectively. The upper shaly unit of the present report, which is mostly of Eagle Ford Age as determined in the previous reports, includes an interval at its base of from 11 to 159 feet of sediments that were included in the Woodbine zone by the earlier
INFORMATION CIRCULAR NO. 60 13
workers. For example, in the Sun, No. 1 Tillis well, as depicted in figures 6 and 10, the upper shaly unit and the basal sand unit of the present study are separated at a depth of 3,260 feet, whereas the Southeastern Geological Society places the upper boundary of the Woodbine microfaunal zone at 3,240 feet, which is 20 feet into the upper shaly unit as used in the present report.
Separations of the Atkinson Formation into the shaly unit and the basal sand unit in relatively difficult up-gradient areas is shown in figures 4, 5 and 6. Figures 10, 11, 12 and 13 illustrate lithologic separations for four down-gradient areas which are widely spaced, and within each of which local correlations are fairly clear.
Criteria For Recognizing The Top of the
Atkinson Formation
For most of the report area the shaly lithology of the upper part (shaly unit) of the Atkinson Formation is overlain by chalk, or marl, of Austin Age. The contact between these distinctive lithologies is easy to recognize in cores or well cuttings, or on electric logs.
---In up-gradient wells located high on the western flank of the Peninsular arch, however, the La Crosse Sandstone (fig. 3) overlies the Atkinson Formation. The La Crosse Sandstone is predominantly composed of quite uniform fine quartz grains, and is light tan to very pale orange in color, calcareous, soft, rarely fossiliferous, and almost entirely without shale associations in most wells. There is a marked contrast, easily recognized in cores and well cuttings, between this sandstone and the Atkinson Formation, which consists of shale and sand which often is micaceous, glauconitic and phosphoritic, and in which the sandstones commonly are of non-uniform grain size.
Criteria For Recognizing The Top of the
Basal Sand Unit, Atkinson Formation
As shown in figure 14, the lower part of the Atkinson Formation is a quartz sandstone, fine to coarse grained, poorly sorted, soft and typically glauconitic, phosphoritic and micaceous. Minor shale, silt and limestone stringers are present. Figure 15 shows that the sand ranges from zero to 379 feet in thickness. The eastern limit of this basal sand unit is in the southeastern part of the study area. Beyond this line the stratigraphic equivalent of the unit consists of the shaly unit of the Atkinson Formation; or (lower in the section) of the oolitic limestone described by the Applins (1965, pl. 10). The contact between this unit and the predominately shaly upper part of the Atkinson Formation is typically marked by a sharp spontaneous potential excursion to the left on the electric log, and by a corresponding increase in resistivity. Even in up-gradient areas in which the contact between the upper shales and lower sands becomes somewhat gradational, these electric log characteristics usually are apparent, though to a less pronounced extent (figs. 4, 5, and 6).

Critez For Recogaidg The Sediments Underlying The Atkinson Fomation
Over most of the report area the Atkinson Formation is underlain by Lower Cretaceous sediments, but in a few wells the underlying sediments are either rock of Upper Cretaceous Age, or Paleozoic rock. These underlying lithologies will be discussed as a guide to determination of the bottom of the Atkinson Formation.
a) The Lower Cretaceous Section
The top of this section usually must be determined from sample examination alone, since it cannot be recognized on the electric log, and since it is rarely cored- For these reasons it commonly is difficult to pick the top of this section with exactness. Recognition of the Lower Cretaceous section is facilitated by figure 16, which shows for selected wells the first lithology indicative of these beds.
In the northern part of the Florida report area, and where most of the well control of this study is located, the upper sediments of the Lower Cretaceous section -which underlie the Atkinson Formation consist of clastic rocks which are slightly calcareous to non-calcareous. These sediments include pastel colored sandstones; red, white and pastel colored siltstones or shales; clear and pastel colored quartz pebbles; and light purple quartzite.
In the southern part of the report area light colored limestones or dolomites are present at the top of the Lower Cretaceous section. However, here these sediments do not immediately underlie the Atkinson Formation of the present study, but rather are separated from it by the intervening oolitic limestone facies of Upper Cretaceous Age, as discussed in the next paragraph.
b) An Oolitic Limestone Faces of Upper Cretaceous Age
Four wells in the southern part of the report area contain a sequence of white and light gray oolitic limestone of Upper Cretaceous Age, having a maximum thickness of 125 feet, as described by the Applins (1965, plate 10). This sequence underlies the predominantly clastic Atkinson Formation as used in the present report. These wells are:

c) Paleozoic Rocks
Near the crest of the Peninsular arch, the Atkinson Formation is underlain by quartzitic sandstones and shales of Paleozoic Age, as reported by Paul L. Applin (1951, table 3) in the following wells: Depth (and sub-sea depth)

STRUCTURE
The structural top of the Atkinson Formation, and of the basal. sand unit of. that formation, are presented in figures 17 and 18. These maps are similar in configuration to the structure of the top of the Lower Cretaceous section as shown on figure 19, which incorporates the results and interpretations of many other workers, including Jordon (1952, fig. 8) and Herrick and Vorhis (1963, figs. 16,17 and 18).
Figure 20 is reproduced from Paul L Applin (1951, table 3) and shows that the Palezoic structure of the Peninsular arch is reflected in the up-gradient lmits, and general configuration, of Lower Cretaceous rocks as mapped in figure 19.
Offshore from the report area, mainland contours of the Lower Cretaceous map are integrated with the results of seismic refraction surveys. Opposite the east coast these contours are taken from a map by Sheridan, Drake, Nafe and Hennion (1966, fig. 10, p. 1985) drawn on top of the Lower Cretaceous section. The contours opposite the Georgia east coast were suggested by a map of the pre-Cretaceous basement by Antoine and Henry (1965, fig. 12, p. 608).
The Lower Cretaceous contours offshore from Dixie County in the Gulf of Mexico were suggested by maps drawn on top of the Upper Cretaceous section by Antoine and Harding (1963, figs. 6 and 7) on the basis of seismic refraction studies. The Antoine and Harding maps reflect an isopach of Cenozoic sediments preparedby Toulmin (1955, fig. 1,p. 1166).

APPENDIX II
42 BUREAU OF GEOLOGY
BUREAU OF GEOLOGY WELL AND LOCALITY DESIGNATION SYSTEM The locality and well numbering system is based on the location of the locality or well, and uses the rectangular system of section, township, and range for identification. The number consists of five parts. These are: 1) a prefix of three letters designating L for locality or W for well and county abbreviation, 2) the quarter/quarter location within the section, 3) the section, 4) the township, and 5) the range.
The basic rectangle is the township which is 6 miles square. It is consecutively measured by tiers both north and south of the Florida base line-an east-west line that passes through Tallahassee. This basic rectangle is also consecutively measured both east and west of the principal meridian-a north-south line that passes through Tallahassee. In recording the township and range numbers, the T is left off the township numbers, and the R is left off the range numbers. Each township is divided equally into 36 square miles called sections, and are numbered I through 36 as shown on the attached diagram.
The sections are divided into quarters with the quarters labeled "a" through "d" as shown on diagram. In turn, each of these quarters is divided into quarters with these quarter/quarter squares labeled "a" through "d" in the same manner. The "a" through "d" designation of quarters may be carried to any extent deemed useful.
The location of the well WLn-2N-2E-21 db shown on the diagram would be in the center of the southeast quarter of the northeast quarter of section 21, township 2 north, range 2 east.
When there is more than one well or locality in a square 40-acre tract (quarter/quarter section) they are identified by either an additional quarter designation or by a sixth arbitrary accession number at the end of the range unit. The abbreviations used for counties are: Alachua Aa Escambia Es Baker Bk Flagler Fg Bay By Franklin Fk Bradford Bf Gadsden Ga &rev. d Bv Gilchrist Gr Broward Bw Glades GI Calhoun Cn Gulf Gf Charlotte Ch Hamilton Hn Ctrus Ci Hardee Hd Clay Cy Hendry Hy Collier Cr Hernando Hr Columbia Co Highlands Hi Dade Dd Hillsborough I DeSoto Ds Holmes Ho Dixie Dx Indian River Ir Duval Iu Jackson Jk
