ABSTRACT OF THESIS SUBSURFACE CHARACTERIZATION AND SEUQENCE STRATIGRAPHY OF LATE MISSISSIPPIAN STRATA IN THE BLACK WARRIOR BASIN, ALABAMA AND MISSISSIPPI A depositional framework for the Mississippian (Chesterian) Pride Mountain Formation/Hartselle Sandstone clastic tongue and the lower Bangor Limestone carbonate ramp in the Black Warrior basin, Mississippi and Alabama, is constructed from approximately 250 geophysical well logs, 15 well cuttings descriptions, and outcrop data. The framework is based upon cross sections, isopach maps, and transgressive-regressive sequence stratigraphy. The Lowndes-Pickens synsedimentary fault block controlled sediment dispersal in during Pride Mountain/Hartselle deposition. The basin filled from the southwest, which pushed the depocenter northeastward during Hartselle deposition. The Hartselle sub- basin is composed of the Hartselle barrier-island and back-barrier deposits to the southwest, including the Pearce siltstone.
