Permo-Pennsylvanian sedimentation in the Oklahoma Panhandle has been primarily influenced, or controlled, by the Sierra Grande uplift, the Hugoton embayment, and the Anadarko basin. Sedimentary facies changes, because of these controlling features, grade from continental and near-shore deposits in western Cimarron County to shelf carbonates in Texas and Beaver counties, and finally to basinal sediments in southeast Beaver County.

Permo-Pennsylvanian deposition began with Morrowan shales and erratic sands upon an eroded Mississippian surface and continued almost without interruption throughout the system up into Wolfcampian time.

Division of the Permo-Pennsylvanian can be made on the basis of correlation from southwestern Kansas, since these units can be traced without great difficulty from this region.

Stratigraphic possibilities for oil and gas accumulation are favorable and appear to far outweigh the structural possibilities.
