Named the Whitesburg limestone for Whitesburg, Hamblen Co., TN. Consists of dark crystalline limestone that at many places in the Appalachian Valley south of Staunton, VA, underlies the dark calcareous shale or limestone of the Athens shale. In most places it rests on the Lenoir limestone but may also overly the Holston marble. Unit is about 500 feet thick. The Whitesburg is of Early Ordovician age (Chazyan). [Chazyan was later changed to Middle Ordovician, hence the Whitesburg is of Middle Ordovician age]

Fetzer Member or facies is assigned to the base of the Whitesburg Formation and overlies the Lenoir Formation in this report. Member consists of a basal metalliferous carbonate and an overlying limonitic/phosphatic claystone. Unit is a dark brown to dark gray, to nearly black, well indurated, argillaceous carbonate with abundant fossils. Bedding is generally nodular to laminated. The Fetzer proper is at least 5 m thick in the eastern outcrop. On the western end of the outcrop, it is about 2 m thick and overlies a more shaly tongue of the Whitesburg. Authors believe that the Fetzer is not a continuous body of rock but instead consists of lenses.
