Summary:

The Camp Creek Formation is here named the youngest unit of the Atlanta Group in the Newnan-Tucker synform near Atlanta, GA. It consists of massive granite gneisses interlayered with thin fine-grained, dark green hornblende-plagioclase amphibolites. Gradationally overlies the Big Cotton Indian Formation; its contacts with other units are sharp and conformable. Intruded by Union City Complex and Palmetto Granite. Thickness is 600 to 3,000 m. Age is Late Proterozoic and (or) early Paleozoic.
