The present study deals with the stratigraphy and petrography of the Upper Cretaceous through Paleocene carbonate sequence obtained from a deep well located in Polk County, Florida. Subsurface stratigraphy was measured and described at one locality from a deep well drilled nearly 8,000 ft (~2,438 m). Based on previous studies and lithologic changes that observed under stereo and petrographic microscope, the studied interval is stratigraphically subdivided into three formations. This study spans a 3400-5700 ft (~1,036-2,193 m) interval encompassing Upper Cretaceous Pine Key and Lawson formations and the Paleocene Cedar Keys Formation. Petrographic investigation of the selected sequence led to identification of lithostratigraphy, depositional environment and diagenetic history of Upper Cretaceous-Paleocene rocks. This study revealed that approximately 1,000 ft (~305 m) of a carbonate-evaporite sequence (mainly dolostone and small portions of limestone) are within the Cedar Keys Formation (3,400-4,400 ft [~1,036-1,341 m]), almost 700 ft (~213 m) white to tan limestone that includes dolomitized portions and small amount of anhydrite belongs to the Lawson Formation (4,400-5,100 ft [~1,341- 1,555 m]), and 600 ft (~183 m) white chalky limestone is from the Pine Key Formation (5,100-5,700 ft [~1,555- 1,737 m]). A number of microfacies were recognized in thin sections representing shallow subtidal to intertidal depositional environments of Lawson Formation and shallow subtidal to supratidal depositional environments of Cedar Keys Formation. Thin section analysis revealed that the Lawson and Cedar Keys formations have a complex diagenetic history that is characterized by several diagenetic features such as micritization, cementation, dissolution, dolomitization, and recrystallization. These complex diagenetic features took place under marine, mixed-marine and fresh water as well as fresh water environments. The Upper Cretaceous Lawson Formation represents a general transgressive to regressive cycle in sea-level while the Cedar Keys Formation indicates more restricted marine environment representing lower sea-levels and multiple transgressive and regressive cycles. / A Thesis submitted to the Department of Earth, Ocean, and Atmospheric Science in partial fulfillment of the requirements for the degree of Master of Science. / Summer Semester 2015. / July 13, 2015. / Includes bibliographical references. / William Parker, Professor Directing Thesis; Seth Young, Committee Member; Yang Wang, Committee Member.

The lithostratigraphy, depositional environment, and diagenetic history of the Lower and Upper Cretaceous rocks have been studied from TEC DIW-1 deep well drilled in the Polk County, Florida. A total of 47 samples were obtained from the core and cuttings in the study area. Microscopic examination of core and samples of drill cuttings from the well provided the basic data associated with the part of the stratigraphic section discussed in the study. Four lithostratigraphic units have been distinguished; (1) the Pine Key Formation, (2) the Atkinson Formation included in the Gulf Series, (3) the Dollar Bay Formation, and (4) the undifferentiated Panther Camp, Rookery Bay and Corkscrew Swamp formation included in the Comanche Group. Carbonate rocks of the study area were classified on the basis of their original depositional texture as outlined by Dunham (1962) and identified facies were compared with standard microfacies types according to Wilson (1975) and Flugel (1982). The determined microfacies of the Pine Key Formation include mudstone and peloidal fossiliferous wackestone suggesting deposition under relatively shallow marine environments. Restricted shelf lagoon to tidal areas are generally suggested environments that reflect deposition settings within shallow marine inner shelf conditions. The undifferentiated Panther Camp, Rookery Bay and Corkscrew Swamp Formation includes five microfacies involving peloidal foraminferal packstone, foraminiferal grainstone, peloidal wackestone, fossiliferous packstone, and dolomitized foraminiferal wackestone. The shallow marine inner shelf settings are also interpreted for this part of the sequence. Shallow marine shelf lagoon to restricted shelf lagoon areas are the environments representing depositional settings of the Dollar Bay Formation that includes the microfacies of intraclastic foraminiferal packstone, foraminiferal wackestone, peloidal foraminiferal packstone, fossiliferous grainstone, algal packstone, and arenaceous peloidal fossiliferous packstone. Microcrystalline marine calcite, pore-filling sparry, isopochaous, as well as pore-filling bladed cements, fabric selective secondary porosity including types of moldic and intraparticle, micritization, dolomitization by aggrading neomorphism or selective replacement dolomitization are the main diagenetic features of the Pine Key, undifferentiated Panther Camp, Rookery Bay and Corkscrew Swamp, and Dollar Bay Formations. On the basis of these features, meteoric phreatic, mixing zone, and marine phreatic diagenetic indicators have been identified. / A Thesis submitted to the Department of Earth, Ocean, and Atmospheric Science in partial fulfillment of the requirements for the degree of Master of Science. / Summer Semester 2015. / July 13, 2015. / Includes bibliographical references. / William Parker, Professor Directing Thesis; Seth Young, Committee Member; Yang Wang, Committee Member.

The purpose of this research was to identify the forcing factors and processes of sediment transport in Perdido Bay. Data were collected from Perdido Bay in July 2011 and used in the development of a three-dimensional sediment transport model using EFDC as well as in the estimation of a sediment budget. Water and bed samples, water quality readings for salinity, temperature, dissolved oxygen, turbidity, depth, and pH, and velocity measurements were collected. Using field and historical data, an EFDC model was created to simulate the processes of salinity and sediment transport. The model successfully demonstrated the movement of sediment through the bay and proved the existence of a turbidity maximum in the northern bay. From this research, it was determined that freshwater inflow is the primary forcing factor in sedimentation and is the main contributor to sediment entering the bay.
