The Wolf Creek Formation of the Atlanta Group, here named in the Newnan-Tucker synform near Atlanta, GA, consists of interlayered laminated amphibolite and biotite-muscovite button schists. It grades into button schists of the Brevard Zone to the northwest, and into Promised Land Formation to the southeast; it is in sharp contact with the Clairmont Formation and Norcross Gneiss to the southwest. Thickness is 1,200 m. Age is Late Proterozoic and (or) early Paleozoic.

The Wolf Creek Formation is removed from the Atlanta Group, here abandoned. The Wolf Creek has been thrust upon Bill Arp thrust sheet rocks in the Brevard Zone and is structurally overlain by the Clairmont thrust sheet; it belongs tectonostratigraphically with the Zebulon thrust sheet. The button schists, phyllonites, and amphibolites of the Wolf Creek probably represent sheared schists, gneisses, and amphibolites of the Zebulon Formation. Age is Late Proterozoic to Early Ordovician(?).

Detailed mapping Wolf Creek Formation in its type area shows that both presence of spessartine quartzites in the Wolf Creek and overall makeup of the unit indicate that it is actually the unnamed mylonitized mixed unit of the allochthonous assemblage. Wolf Creek Formation is abandoned and its rocks reassigned to mixed unit of allochthonous assemblage. Report includes geologic map and correlation chart.
