Abstract
Outcrops and exposures of the Winona and Tallahatta formations in the Duffee Quadrangle in Newton and Lauderdale counties were mapped and analyzed. The rock type, composition, structures, and fossils were identified at each site; unit thicknesses were measured, and stratigraphic relationships were analyzed for available exposures. Using GPS coordinates, each site was mapped on Google Earth Pro. The data collected at each site, aerial photographs, and topographic maps were used to identify each formation. The variability between previous works and this study was analyzed. The primary rock type found in the Tallahatta Formation is siliciclastic silty claystone and sandstone; some units were glauconitic, and the color ranges from tan to olive green. The Winona Formation is glauconitic iron-rich red sandstone. Storm deposits were identified in the Winona Formation and in the Tallahatta Formation; there were fining-upward sequences in these deposits in the sandstone units. Some layers of sandstone in both formations contained bivalve and gastropod molds.
