Scott shale [of Pottsville Group]. Mainly argillaceous and sandy shales, but includes many beds of shaly sandstone, a few massive sandstones, and five or six coal seams, all very similar to those of Wartburg sandstone. Contains more shale than sandstone, and sandstones are thinner than in the Wartburg. Thickness is 450 to 600 feet. Overlies Wartburg sandstone and underlies Anderson sandstone. [Age is Pennsylvanian.]
Named from its frequent occurrence in Scott Co., eastern TN.
