Abstract:
The area of investigation in southwestern Oklahoma extends from Cement field, Tps. 5-6 N., Rs. 9-10 W., northwestward along the north flank of the Wichita Mountains to the Oklahoma-Texas boundary. A study of Pennsylvanian sediments in this area reveals conspicuous facies changes both laterally and normal to the mountain flank. In the lateral facies changes show a close relationship to the provenance from which the sediments were derived. Correlation difficulties are increased because of these facies changes. Fusulinids provide reliable age determinations when present. The Pennsylvanian rocks are dominantly clastics. The principal facies near the mountain front is "granite wash," a coarse clastic sediment composed primarily of igneous rock fragments with variable amounts o detrital carbonates and chert. Subordinate facies are arkosic sandstones, arenaceous, silty shales and thin, argillaceous limestones. These continental and transitional facies interfinger basinward with normal marine sandstones, shales, and limestones.
