Summary:

Named the Witten limestone for Witten Valley Church, Tazewell Co., southwestern VA. Consists of laminated limestone, calcilutite, CRYPTOPHRAGMUS beds, and CAMAROCLADIA beds. Average thickness is 100 feet. Intertongues with underlying Bowen formation, but northeast of Five Oaks, Marys Chapel and Thompson, it lies disconformably on the Wardell formation or Gratton limestone. Underlies the Moccasin formation. The Witten is of Middle Ordovician age.

Summary:

Geographically extended the Witten limestone to northeastern TN. Locally in the Cumberland Plateau, calcilutite part of formation reaches a thickness of more than 500 feet.

Summary:

Revised the Witten Formation to be included in the Chickamauga Group in eastern TN. Averages about 50 meters thick. Overlies the Bowen Formation of the Chickamauga Group, but where Bowen is absent, lower contact with the Wardell Formation of the Chickamauga Group is difficult to establish. Underlies the Moccasin Formation.

Summary:

In cross section E-E', in subsurface of southwestern VA and east-central WV, Witten Limestone is extended into WV in Pendleton Co. Replaces the McGraw Limestone of Perry (1964). Shown as part of the Black River Group. Age is Middle Ordovician (Blackriveran).
