Comments First published use in Pittsburg Co, OK, in the Arkoma basin. Probably named for the town of Savanna. No type locality designated. Occurs in the McAlester coal district in the McAlester quadrangle, and in the Lehigh coal district in the Atoka and Colgate quadrangles. In the McAlester coal district, consists generally of a series of sandstones and shales about 1,150 ft thick; there are five principal sandstone beds with varying thicknesses from nearly 50 ft to 200 ft. These sandstones are brown or grayish-brown, fine grained, and compact, generally thin and in part shaly. In the Lehigh coal district, is similar to sandstones described in the McAlester coal district, but these sandstones become chert breccias throughout east side of the Lehigh Basin. (Taff, 1899).
