The Whitesburg Formation is a dark limestone with interbedded shales geologic formation in Tennessee and Virginia.[1] It preserves fossils dating back to the Ordovician period.
History
[edit]The Whitesburg Formation was formally proposed in 1930, though E.O. Ulrich had used the name prior to the formal proposal.[1] The Whitesburg formation was later downgraded to the Whitesburg limestone, and was considered a basal member of the Blockhouse Shale.[2] The Whitesburg Formation was then elevated back to formation status with the Fetzer member assigned as the basal member.[3] The Fetzer is not considered to be a continuous body of rock, and exists in the Whitesburg formation as lenses.
