Rice, Conservation Florida State Board of Conservation Sir: have honor transmit a report entitled STRATIGRAPHIC AND PALEONTOLOGIC STUDIES OF WELLS IN FLORIDA-No. Storrs Cole of Ohio State University, Columbus , Ohio, to be published as Geological Bulletin No. This paper deals primarily with the cuttings and cores from a well drilled River Oil northeast Florida Corporation's as a test Hilliard Turpentine 1, namely Company Mary's well near Hilliard , Nassau County. also includes studies of samples from well drilled for water for the City of Quincy, Gadsden County. Studies and reports similar to this one have been a policy of the Florida Geo- logical Survey for some time they have proven only academic practical importance. It is from such studies that inti- mate knowledge of the character, thickness and age of the underlying formations is obtained and this is particularly valuable now in view the increased interest in Florida as an oil producing State. est has been This inter- tremendously stimulated by the discovery of oil in a deep test at Sunniland southern Florida. , Collier County, Cypress Swamp area This well was drilled by the Humble Oil and Refining Company and has a total depth of 11,626 feet, the oil coming from porous limestone stratum found at 11,113 feet.

It is a pleasure to acknowledge the assistance easier Gunter than has which would has have given freely made been work otherwise. this Mr. bulletin Herman of his time and has offered many valuable suggestions. The staff Florida Geological Survey was most cooperative. Mr. James R. Galbraith Jr. described the samples from the City of Quincy well, Mr. Dean W. Wilson drafted the well logs, and Mrs. A. J. Rogers aided with the manuscript. Dr. Joseph A. Cushman examined and commented on certain of the smaller Foraminifera and Dr. Wayland Vaughan furnished photographs and advice concerning certain large Foraminifera. Dr. J. Osborn Fuller did extensive work on the igneous rock encountered in the Hilliard Turpentine Company well. Dr. John Wells iden- tified the shark's teeth, and to him must be accorded special appreciation micrographs labors illustrating taking external excellent photo- appearance larger Foraminifera. The writer made the thin sections and took the major number of photomicrographs of these. CITY OF QUINCY WATER WELL (W-4)* In the spring of 1928 the City of Quincy, Gadsden County, Florida, drilled a well to a depth of 1370 feet on the water- work's property located on the Bainbridge road. This well was drilled by the Gray Artesian Well Company of Pensacola and samples were furnished to the Florida Geological Survey. These samples represent general foot intervals. The elevation of the well is 149.7 feet above sea level.

The Hawthorn in this area is composed chiefly of sandy clay much which has appearance fuller's earth. There are also some thin marl beds and beds of sandstone. TAMPA LIMESTONE.-At 210 feet the samples contain grayish white, dense fossiliferous limestone. the sample at 220 feet Sorites sp. and Peneroplis proteus d'Orbigny were found, and at 230 feet good specimens of Archaias floridanus (Conrad) were recovered. Although the upper portion of the Tampa limestone this area is a pure limestone, slightly arenaceous limestone. the lower portion is largely a There are one or two beds of a greenish clay interbedded with the limestone. The Tampa has a thickness of 175 feet in this well. OLIGOCENE SUWANNEE LIMESTONE.-At 390 feet specimens of Rotalia were found which seems to be the same as the one described 3 from Mexico as Rotalia mexicana Nuttall, variety mecatepecensis Nuttall. the top of the Oligocene. The first large Foraminifera The appearance of this form marks were found at 410 feet. this sample there were two species of Lepidocyclina, L. (Lepidocyclina) yurnagunensis Cushman, namely, variety morgan- opsis Vaughan, and L. (Eulepidina) favosa Cushman. This sample also contained specimens of Operculinoides which are referred to O. vicksburgensis Vaughan and Cole.

The samples below 410 feet are relatively unfossiliferous until the sample at 505 feet was examined. This sample con- trained abundant specimens of Heterostegina texana Gravell and Hanna. This species has been reported from two other wells in Florida. the Port St. Joe test well (W-288) H. texana was found at a depth of 859-870 feet4 and in the Cory No. 1110 feet. 1 (W-445) this species occurred at a depth of 1100- 5 In the Port St. Joe Test well 3 (W-288) H. texana appeared 190 feet below the top of the Oligocene, in the Cory No. (W-445) occurred 200 feet below the top the Oligocene, but in the City of Quincy well (W-4) this same interval was 125 feet. The samples below 505 feet were sparingly fossiliferous or unfossiliferous until the sample at 615 feet was examined. Such fossils as did occur in this interval have been discussed. MARIANNA LIMESTONE.--At 615 feet new species appear in abundance, among which were identified Lepidocyclina (Lep- idocyclina) mantelli (Morton) and Operculinoides dius (Cole and Ponton) These species are diagnostic of the Marianna limestone on outcrop. But, associated with these two species are others which have not been recorded previously from the Marianna limestone. this Cushman, sample specimens assigned Cushman, (L.) and parvula Operculi- noides antiguensis Vaughan and Cole were found in associa- tion with the two typical Marianna species. L. (L.) parvula has been reported from the Port St. Joe test well 3 (W-288) at a depth of 1017-1035 feet. The writer has found this same species at a depth of 440-450 feet in the test well drilled by the Calhoun Gas and Oil Company (W-7) about one-half mile northwest of Ciarksville, Calhoun County, Florida. neither these wells was (L.) parvula (Eulepidina) undosac ___ FLORIDA GEOLOGICAL SURVEY-BULLETIN TWENTY-SIX from above but the writer has reason believe that this not the case. more wells are studied , the explanation may found. Howe 'who recently made a thorough and detailed study fauna Glendon formation reports that (Lepidocyclina) strata the mantelli Glendon (Morton) type was found locality But basal other Lepidocyclina were found in association with mantelli. Cer- tain Lepidocyclina may have longer ranges than was formerly thought, or the formational boundaries may have been chosen incorrectly.

These specimens were studied in great detail and then were sent to Cushman so that the writer's identifications could checked against the collections the Cushman Laboratory. Dr. Cushman not only examined the specimens but in most cases was able to check them against the types or paratypes. After this examination Cushman wrote think the ma- trial is Oligocene." This opinion exactly coincided with that of the writer. The specimens most certainly did not come from a lime- stone. The type preservation preserved in a clay material. indicated that they were This might be used as evidence that the entire section from 400 to 500 feet could not have been limestone, although admittedly the greater portion it could have been. As Foraminifera of definite Oligocene age were found only in this one sample, the Oligocene section in this well must be thin. From the evidence at hand it is not possible to state the exact point at which the well penetrated the Oligocene. The presence Eponides manrannensts would suggest that the Oligocene in this well should be correlated with the Marianna limestone, but again definite commitments should not be made.

As far as could be determined the base of the Salt Moun- tain limestone occurred at 1910 feet. The thickness of the Salt Mountain limestone in this well is 125 feet. The Gran- berry well (W-285) had thickness 194 feet Salt Mountain limestone. It is entirely possible that the base of the Salt Mountain limestone is lower in the Hilliard Turpen- tine Company well (W-336) . If the zone of lignitic fragments in the limestone is disregarded, the base of the Salt Mountain limestone could be placed at 2025 which would give a thick- ness of 240 feet. More wells will have to be studied in this area before the actual thickness can be determined. Except for the upper portion which contained the Disco- cyclinidae the remainder of the Salt Mountain limestone in this area does not contain recognizable fossils. ACKERMAN FORMATION.-Below the base of the Salt Moun- tain limestone in this well there is a section of unfossiliferous limestone.

These limestones are cream to tan colored, hard limestones which contain Borelis gunteri Cole and Borelis floridanus Cole in their upper por- tion. Small Foraminifera associated with Borelis, but are badly preserved. The lower portion of these lime- stones are unfossiliferous or sparingly fossiliferous. The term Cedar Keys formation is designed to cover the rocks encountered in wells in peninsular and northern Florida from the first appearance of the Borelis fauna to the top of the Upper Cretaceous.

Mrs. Applin has placed the top of the Eutaw at 3748 feet, apparently basing her opinion on the occurrence of lignite in the sample at this depth. However, lignite was found above this depth and the most marked lithologic change occurred at 3440 feet at which point the writer believes the well entered the Eutaw.

Campbell states that Mrs. Applin determined the top Tuscaloosa at 4547 feet or 287 feet lower than the point chosen by the writer. The bottom of the Tuscaloosa was determined to be 4640 feet. The thickness of the Tuscaloosa is 380 feet. The lithologic characteristics of the Tuscaloosa are shown on the graphic log (fig. 3) Red, yellow and mottled shales appear only in the lower 45 feet.

Osborn Fuller at the request of the writer, and his report on this rock is given in full in Appendix A. There has been considerable speculation as to the age' of the rocks from 4640 to 4795 feet. been summarized under the topic Hilliard Turpentine Company well The various opinions have "Previous Studies on the (W-336)" and need not be repeated here. It is the opinion of the writer that the section from 4640 to 4795 feet represents a non-marine phase and that the age of these rocks is Triassic. The writer believes that they are equivalent to the Newark series. Fuller has established that the age of the diabase which intrudes this shale is Newark. This fact alone does not prove the age of the shale, but it is suggestive. Knopf has re- ported on his examination of a piece of this shale to Schu- chert that lithologically it is distinct and different from the Chattanooga shale. Knopf found that the shale from this well was composed of kaolin which was deeply stained with carbonaceous matter, a fact which would suggest that the shale was non-marine in origin. Inasmuch as this dark gray shale is overlain by the Tusca- loosa, it is logical to assume that this area was land during Jurassic and Lower Cretaceous time. Therefore, only posits which were favorably situated could escape removal. Such is the case of Triassic deposits elsewhere in the eastern United States which accumulated in basins produced by fault- ing and because of the conditions so produced were able to survive the long period of of the Cretaceous seas. As stated previously in erosion this before the encroachment bulletin no organisms were found this shale, and examination the specimen Stephenson's possession did not convince the writer that this specimen represented an ostracod.

The pyroxene Hypersthene occurs both the upper and lower chilled phase Palisade and seems to part the incompatible diabase. with Hypersthene pigeonite i is present with unchilled pigeonite in some grains in the Florida well specimens. The dominant feldspar of the top of the Palisade sill shows same range in composition as that the Florida well while the feldspar of the lower part of the Palis ades is more basic and the central part more acidic than that of the upper chilled seems zone.

They have a marked alkaline character with sodium predominating over potash. Basaltic types without analcite are rare. high alkalinity of these rocks differs from the Florida speci- men and seems to preclude correlation.

The dikes New England, New York, the Monteregian Hills, and the Balcones Fault zone are all much more alkaline than the diabase of the Florida well. Only two groups of dikes seem to be similar to the Florida diabase in composition the pre-Cambrian dikes of the Adirondack Mountains, and the Triassic dikes found from Nova Scotia North Carolina. The diabase the Florida sample agrees surprisingly well in mineral composi- tion with the upper chilled zone of the Palisade diabase. The sample from Florida as Triassic in age.
