The part of the Ardmore basin discussed in this paper includes the area south and west of the Arbuckle Mountains, east of the Cruce-Velma trend, and north of the Loco-Criner Hills area; it includes parts of Bryan, Marshall, Johnston, Love, Carter, Stephens, Grady, and Garvin counties. A small part of the Anadarko basin is discussed showing the onlapping of the Deese beds on older Pennsylvanian and pre-Pennsylvanian of the Pauls Valley uplift.

In the Ardmore basin the Deese lies unconformably on top of beds from the Arbuckle to Dornick Hills age. The area of greatest pre-Deese truncation is the Healdton-Criner area. A large part of the basin has Permian beds and Cretaceous beds lying unconformably on Pennsylvanian and pre-Pennsylvanian rocks. A considerable part has Pennsylvanian beds at the surface. The only pre-Pennsylvanian beds exposed in the basin area are on the Mannsville anticline in Marshall County. There are pre-Pennsylvanian rocks cropping out in the Arbuckle Mountains on the north flank of the basin and in the Criner Hills area on the south side of the basin. The Deese has a maximum thickness of 8,000 feet, Dornick Hills 3,000, Springer 6,000, Caney shale 500, Sycamore 600, Woodford 700, Hunton 400, Sylvan 400, iola 1,100, Simpson 2,400, and Arbuckle 7,300 feet. These are maximum thicknesses and are probably not reached in any one place. Probably the greatest thickness of both the Pennsylvanian and pre-Pennsylvanian is in the area of Ardmore, Oklahoma.
