:LIMTER OF TRANSMITTAL Orida eoloical Survey October 10, 1953 MR. CIHARIE BEVIS, Supervisor FLORIDA STATE BOARD OF CONSERVATION TALIAHASSEE, FIAORIDA The sediments of Miocene age exposed in the State of Florida are the type marine section for all of the Miocene rocks of the southeastern United States. These rocks are economically important throughout much of the Gulf Coast in that they contain oil in the State of Louisiana, and possibly Mississippi, and considerable quantities of phosphate in Florida. A better understanding of the Miocene stratigraphy is of tremendous importance in the discovery iiof additional reserves of both oil and phosphate.i This report, entitled, "Contribution To The Study Of The Miocene Of The Florida Panhandle," was prepared by Dr. Harbans S. Puri, Micropaleontologist of this department. It is a comprehensive report that contributes much new data to the stratigraphy of the Miocene section. In part, the report is also a partial reprint of Bulletins 4 and 9, issued by this department in former years, the editions having been exhausted. We have had numerous requests for reprinting these bulletins and we are delighted to bring the nomenclature and taxonomy up to date and to make these papers available once again. Dr. Puri has also contributed to the knowledge of the microfauna of these beds, through the description of a number of species of ostracods.

tandard section of the Miocene of western Florida, there nsiderable doubt as to the sequence of the various forhis doubt may be attributed to the scattered nature of dip, thickness and structure of these beds. Stratigraphy entirely on supposed faunal evolutions, disregarding bioesent study embraces Okaloosa, Walton, Holmes. Washy, Jackson, Calhoun, Gulf, Lberty Fraklin, Gadden, Leon dWakulla counties. Samples from 58 outcrops, 20 auger wo water wells were studied. Stratigraphic sections and he Miocene of the Florida panhandle indicate the presumber of lithofacies and biofacies, which are a measure nee of similar conditions and are reflected in both the and fauna. Similar depositional types of equivalent age ered as stages while the dissimilar components within are designated as facies. Three stages are recognized, mpa Stage includes in part the "lower Miocene sedihe Florida panhandle and its equivalents in the central n Gulf States. The type area is near Tampa Bay and infamous Ballast Point locality which is now largely cove Sixmile Creek locality at Orient, Hillsborough County, and pre-Alum Bluff Ages. In the Florida panhandle, cies are recognized: a calareous St. Marks facies and al httahoochee facies. octawhatchee Age ("middle Miocene") in the Florida and their equivalents in the central and western Gulf y, Florida.

icene rocks of the Florida Panhandle are the type marine he Gulf and southeastern United States and the present hese sediments was logically sponsored by the Florida Survey. The major portion of the work was done at of the degree of Doctor of Philosophy in June, 1953. idy was initiated toward the end of 1949, when the the task of a detailed study of the ostracode fauna of e of the Florida Panhandle. Several taxonomic and ral problems were encountered during this study and ried to unravel some of them (Puri, 1952a, 1952b, 1953a, c). When the ostracode faunal studies were ifinally n the middle of 1950, it was realized that the faunas ee with the standard stratigraphic section set up by 926), Mansfield and Ponton (1932), Cushman and PonSand Smith (1941). A different, but more logical in, was offered by Vernon (1942), who, after a detailed Ssections in Washington and Holmes counties, came to lon that the Shoal River formation was possibly the s of the Chipola formation, and that the Ecphora and facies were definitely the updip facies of the Area and es. This radically different interpretation was based that nowhere in Washington and Holmes counties was iver formation known to overlie the Chipola formation te Ecphor and Cancellaria facies known to overlie the area considered in this report (Washington and Holmes counties) n Walton and Okaloosa counties." f 1950, and it was suggested that the study be expanded 7i= ===== ==== == == ==A

Matson and p (1909, pp. 74-84) referred to it as a formation. Cooke and som (1929) abandoned the term Chattahoochee formation bea it seemed to be the same age as the Tampa. The fossiliferous ons of the Chattahoochee limestone equal the Tampa accordo Mansfield (1937) and Cooke (1945). The limestone is very vesce and appears to be largely white silt, bu it is fossilifrous contains several molluscan casts. Farther west this facies is ominately silty although in the vicinity of type locality several tone beds are quite common. The section at Chattahoochee is ibed as lower Miocene in the Third Field Trip of the Southrn Geological Society (1945).

HISTORY OF DEPOSITION The greatest part, about 400 feet, of the type Miocene beds of Panhandle Florida are made up of sediments deposited in shallow rnarine (neritic) waters. The shallow-water origin of these deposits coupled with the seaward thickening of about 1000 feet indicates the occurrence of subsidence during deposition. The rateiiiiiiiiii of sedimentation was not uniform because there were a series of transgressions and regressions of the sea which produced cyclic sedimentary units. The transgressions seem to have been rapid as is shown by several overlaps and disconformities. The regressions were slow. The slowness of such regressions resulted in the deposition of a greater proportion of the sediments during this phase of the cycle. The cyclic changes produced in the sediments by such transgressions and regressions are of horizontal as well as of vertical distribution. This has resulted in the grouping of sediments of similar lithology in belts that generally parallel the "hay line." The sediments deposited during the Miocene in Panhandle Florida show that the shore line occupied different positions bordering the land mass at various times. Such positions resulted from the advance or retreat of the sea in its fluctuations. The retreat of sea coupled with uplift has resulted in the occurrence of successively younerr marine formations in a seaward clirection. That

During regression the sea "las of" lde seiments, depositing younger sediments as it retrats eah scceding sediment. being younger than the underlyin roks;suc a uccession of sediments will naturally result in the eposue of pressively older beds in a landward direction. The erms"marne If lap" (Malkin and Echols, 1948) or "marine regessve verap"(Grabau, 1924) have been used to embrace sedient deosiedluring the period of regression of sea. Sinc reresionis a later phase of transgression itself, both are ntereltedandform a complete stratigraphic cycle.

88 FLORIDA GEOLOGICAL SURVEY-BULLETIN THIRTY-SIX reflected in lithology as well as in fauna. 1Lithologically or faunally dissimilar components within the three stages recognized here are designated as facies since they oceapy approximately the same timestratigraphie position in the section and also interfmnger with one another. The detailed examination of the Micene section shows that the lithologic and biologie patterns, resulting from shifts in time and space distribution of environments, coincide with the formational and famnizonal boundaries. It is apparent from stratigraphic seetions of the Miocene of the Florida panhandle, (figures 2 and 3) that there are three well-developed stages, each bounded by an unconformity at both top and bottom: Tampa Stage, Alum Bluff Stage, and Choctawhatchee Stage. TAMPA STAGE Tampa seas were transgressive over the eroded surface of the Oligocene or older limestones. Early in this transgressive period a "limy" lithofacies (St. Marks) was deposited downdip, and late during this transgression and the regression that followed a more clastic (Chattahoochee) lithofacies was deposited updip. Both of these facies are gradational and this gradation is distinct. That Tampa seas were moderately shallow-warm is shown by fossil remains of genera like Archai"s, Peneroplis, Elphidium, Krithe and Clithrocyther-idea. The Chattahoochee facies was deposited nearer shore than the St. Marks facies. There is a slight time break between Tampa and Alum Bluff Stages. It is noticed in the vicinity of Willis on the Chipola River and in the vicinity of Carr on Tenmile Creek. An unconformity is apparent between the St. Marks and the Chipola sediments wherever exposed in this area. Tampa waters received more terrigenous material which was in places rapidly deposited without much sorting (Chattahoochee facies). The St. Marks facies was deposited under deeper water where precipitation of lime was in progress and only minor quantities of clastics, largely quartz sand, were being deposited. Some of the lime was later replaced by silica, thus giving rise to "Tampa silex beds." ALUM BLUFF STAGE "Middle Miocene" sediments of the Alum Bluff Stage were deposited unconformably on the Tampa. Alum Bluff Stage is divided into four lithofacies : Hawthorn, Chinoa, Oak Grove and Shoal

Haplacytheridea bassleri, which is very abundant in the Shoal River facies, is a brackish-water formt (Stephenson, 1938, p. 185) and it dominates the modern bay microfauna. Shoal River facies are mostly brackish with a slight infdux of inner neritic forms, which though not living in the modern bays, are represented by empty tests which are washed in the bays from the open sea at high tides.

SYSTEMATIC TREATMENT following pages will be found the known species of enera of Foraminifera that occur in the Miocene of the Panhandle. The species are arranged by their geologic on the plates, but only the dominant and diagnostic species ious facies are refigured. Cushman (1930) and Cushman S(1932) did a comprhensive job of escribing and ilranged by the geologic sequence of the diagnostic species produced in the end of this report. A comprehensive synthe species is included i the systematic part and the ure followed here is that which is in current use. Notes agnostic characteristic of species, whenever they seem are added. The reader i referred to Cushman (1930) a man and Ponton (1932) for more specific details. Genus PROTEONINA Williamson, 188 Proteonina difflugiformis (H. B.
