Revisions of Outcrop Lithostratigraphic Nomenclature in the Lower to Middle Mississippian Subsystem (Kinderhookian to Basal Meramecian Series) Along the Shelf-Edge in Southwest Missouri, Northwest Arkansas, and Northeast Oklahoma

S. J. Mazzullo, Darwin R. Boardman, Brian W. Wilhite, Cory Godwin, Beau T. Morris


The lithostratigraphy of the Lower to Middle Mississippian section is described and documented, and several nomenclatural revisions are suggested, for outcrops south of the paleoshelf-edge in southwest Missouri, northwest Arkansas, and northeast Oklahoma. Nomenclatural revisions are: (1) use of the St. Joe as a group, rather than as a formation or member, that includes, in ascending order, the Kinderhookian Compton and Northview Formations and the basal Osagean Pierson Formation; (2) abandonment of the Baird Mountain Member as the locally present upper part of the Northview Formation; (3) recognition of the Pineville tripolite facies as an intra-Osagean subunconformity weathered horizon at the top of the Reeds Spring Formation; (4) abandonment of the name Burlington-Keokuk Formation in lieu of the Bentonville Formation, maintaining the Short Creek Oolite as a member at its top; and (5) discontinued use of the name Warsaw Formation (basal Meramecian) and its replacement by the name Ritchey Formation. These revisions acknowledge the significant lithologic differences between some of the units here and at their type localities along the Mississippi River, and they result in a clearer and more consistent lithostratigraphic framework in the tri-state field area. This lithostratigraphy ultimately can be readily applied to the petroliferous subsurface in Kansas and northern Oklahoma.
