Anderson sandstone [of Pottsville group]. Sandstones, sandy and argillaceous shales, and coal beds, like preceding formations [Scott, Wartburg, and Briceville]. Bottom of series is marked by massive sandstones in beds from 20 to 50 feet thick, with total thickness of 100 to 120 feet. Above these follow 300 to 400 feet of shales interbedded with thin layers of massive sandstone which are capped in higher mountains by thick, massive sandstones like bottom layers. Appears on mountain tops. Original thickness unknown, but 650 feet remain. Overlies Scott shale. [Age is Pennsylvanian.]
Named because of its frequent occurrence in Anderson Co, eastern TN.
