Documentation for one or more major gravity slide thrusts and numerous lesser slides is recognized in the Eola, Southeast Hoover, and Southwest Davis oil fields. Slides moved to the northeast and northwest in Middle Pennsylvanian, subsequent isoclinal folding in Late Pennsylvanian. Small depositional structures within beds. The tensional segment of the major slide fault now coincides with the trace of the Washita Valley Fault. The compressional end of the slide coincides with the Reagan Fault in the east and the frontal Eola Fault in the west. Tectonic breccias. The Arbuckle Group, which had been beneath at least 5,000 ft of younger strata, was exposed immediately following the slide.--Modified journal abstract.
