The study area is located along Highway 20 east Cartersville Georgia, where outcrops of the Weisner Formation are exposed. The section consists of two main facies, the sandstone facies and shale facies. Parallel lamination and cross stratification are commonly observed sedimentary structures at this location. Petrographic study reveals that the grains in the sandstone are dominantly quartz, and to a smaller extent feldspar and mica. The shale facies is rich in Al2O3 and K2O compared to the sandstone facies. No fossil is observed in any of the two facies. Petrographic studies also indicate igneous, metamorphic, and sedimentary source rocks for these clastic rocks. The shale facies is very rich in mica, with muscovite and some kaolinite. Lithologic features and grain size suggest that the Weisner Formation was probably deposited in a shallow marine environment.
