Borden Formation

The Mississippian Borden Group (sometimes Borden Formation) is a mapped bedrock unit in Kentucky, Indiana, Illinois, Ohio, West Virginia, and Tennessee. It has many members, which has led some geologists to consider it a group (for example in Indiana) rather than a formation (for example in Kentucky).
