Stratigraphic Study of Pennsylvanian and Permian Rocks in the Western Mid-Continent: Abstract

Bailey Rascoe1


In the western Mid-Continent the typical post-Cherokee (lower Des Moines) Pennsylvanian, and pre-Leonard Permian, sediments consist of limestone formations on the shelf area and dark shales in the Anadarko basin; shelf-to-basin facies changes are abrupt.

These deposits are considered the product of a tectonically controlled marine advance from the Ardmore-Anadarko basin foredeep, and retreat toward the west Texas region. During the transgressive phase the Anadarko basin subsided and expanded. Consequently, Morrow, Atoka-Des Moines, and Missouri sediments onlapped the shelf area; Marmaton and Missouri shelf-limestone to basin-shale facies changes were located progressively shelfward; and the Cottage Grove, Tonkawa, and Lovell blanket sandstones in the Anadarko basin successively increased in areal extent. During the regressive phase the Anadarko basin gradually ceased to subside, diminished in areal extent, and became an embayment of the Permian basin to the southwest; as a result, Virgil and Wolfcamp shelf-limestone to basin-shale facies changes were located progressively basinward; the Elgin and Laverty sandstones in the Anadarko basin decreased successively in areal extent, and semi-continental clastics and evaporites were deposited over the western Mid-Continent as the sea withdrew toward the southwest.
