Limestone Gap (OKPAlg;0)

State	Oklahoma
Name	Limestone Gap
Geologic age	Early Pennsylvanian
Lithologic constituents	Major Sedimentary > Clastic > Sandstone (Bed) Sedimentary > Clastic > Mudstone > Shale (Bed)
Comments	Named as a formation of Springer group of Morrow series of the Bendian period. Type locality designated at Limestone Gap (source of name), sec 31, T2N, R13E, Atoka Co, OK in the Ouachita tectonic belt province. Occurs in the frontal Ouachitas, Ardmore basin, and Arbuckle Mountains; in the Ouachitas, is well exposed along Choctaw fault zone; in Ardmore basin, is well developed; in Arbuckle Mountains, areal distribution is exceedingly spotty and not traceable. Consists of gray-greenish, dark gray, and black bituminous shale with a profusion of siderite layers and concretions. In Ardmore basin, upper part ordinarily is predominantly silty and finely arenaceous; lower part contains in a few places thin arenaceous streaks, also contains scattered drab argillaceous limestone concretions with many fine plant fragments. Thickness is 1,250 ft about 5 mi east of the village of Springer, in a tributary of Cool Creek, along railroad track near center of SE1/4 sec 1, T3S, R2E, Carter Co, OK; thickness at type locality is 44 ft. (Harlton, 1938).
