Reference Core and Correlation of Key Beds in the Petersburg and Linton Formations (Pennsylvanian) in Indiana

Abstract

"The Indiana Geological Survey recovered a nearly continuous core from a location near the type locality of the Survant Coal Member of the Linton Formation. This core spans a stratigraphic interval within the Desmoinesian Series extending from rocks immediately above the Houchin Creek Coal Member of the Petersburg Formation to an unnamed shale in the Staunton Formation immediately below the Seelyville Coal Member. This core is herein designated a reference core for the Houchin Creek Coal Member of the Petersburg Formation; the Survant Coal, Velpen Limestone, Mecca Quarry Shale (new name), and Colchester Coal Members of the Linton Formation; the Seelyville Coal Member of the Staunton Formation; and the boundary between the Petersburg and Linton Formations."
