Pg. 487, 508. Charleston sandstone. Coals and sediments latter usually coarse, overlying Kanawha black flint, and extending upward to the red shales ["Pittsburgh Reds"?] are well exposed in bluffs back of Charleston. The sandstones are usually feldspathic and friable; the beds are frequently conglomeratic, but the pebble-bearing horizons vary greatly in different parts of field. Thickness 320 to 420 feet. Overlies Kanawha formation. Age is Pennsylvanian. [Includes Allegheny formation and lower part of Conemaugh formation.]
[Named from exposures at Charleston, Kanawha Co., western WV.]

Charleston Sandstone near Charleston, WV, is a nonmarine unit. The Charleston is of Middle Pennsylvanian age (palynomorphs), and is younger than the Kanawha Formation and older than the Conemaugh Formation.

Reassignment of Mahoning Sandstone Member in WV from Conemaugh Formation (by Krebs and Teets, 1914), where it was misused, to Charleston Sandstone (by Englund and others, 1979) probably is incorrect.
