Hartshorne Sandstone (OKPAha;0)

State	Oklahoma
Name	Hartshorne Sandstone
Geologic age	Middle Pennsylvanian
Lithologic constituents	Major Sedimentary > Clastic > Sandstone (Bed) Minor Sedimentary > Clastic > Mudstone > Shale (Bed) Incidental Sedimentary > Coal (Bed)
Comments	First published use in Pittsburg Co, OK, in the Arkoma basin. Probably named for the town of Hartshorne. 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. Is the oldest unit mapped. In the McAlester coal district, is a brown to light-gray sandstone 200 ft thick. Near the top, beds are very thick and some are massive, and occur as roughly rounded masses and thick ledges. In lower part, many of the beds are thin and slabby and associated with sandy shales. In the Lehigh district, occurs in the valley of North Boggy Creek; is a brownish fine sandstone which changes to a breccia of chert fragments in brown sandstone matrix. Lies below the Hartshorne coal and is separated from it by thin, variable bed of shale. (Taff, 1899).
