There are three members of the Borden Group in Indiana. Edwardsville Formation The Edwardsville Formation is a geological structure in the Borden Group, of the Lower Mississippian sub system, (Osagean, late Tournaisian). Crinoids fossils can be found in the formation. New Providence Shale The New Providence Shale is a geologic formation in Indiana. It is a basal clay-shale geologic formation in Indiana named by Charles Butts and William W. Borden in the 1874 after New Providence, Indiana (now Borden). Spickert Knob Formation The Spickert Knob Formation is a geologic formation in Indiana. == External links ==
