Subsurface stratigraphic and structural analysis, Cherokee group, Pottawatomie County, Oklahoma. Part 2
Cherokee strata onlap the pre-Pennsylvanian unconformity surface. This surface is stream dissected and shows a well-developed dendritic pattern with northeastward drainage. The most conspicuous topographic features on this surface are produced by the Morvin Pool Horst block and the Seminole-Cushing ridge. The Cherokee group consists of an alternating cyclic succession of transgressive and regressive rocks that are of a shallow marine and deltaic origin. Middle Pennsylvanian (Desmoinesian) marine transgression occurred as the Cherokee sea advanced across the area from the northeast due to the presence of the Seminole-Cushing ridge. Sandstones of the Booch, Bartlesville, Red Fork, and Skinner zones were deposited by a sediment dispersal system of prograding deltaic distributaries that flowed primarily from northwest to southeast. The majority of Cherokee pools produce from combination structural-stratigraphic traps. Sandstone geometry associated with structural nosing is the most common trapping mechanism.
