Summary:
The Proctor Creek Member of the Canton Formation, here named in the Dahlonega, GA, area, was previously mapped as Carolina Gneiss by Keith (1909). It consists of fine- to medium-grained muscovite-garnet-biotite-quartz schist with a silvery luster. Sharply overlies iron formation or amphibolite of the Pumpkinvine Creek Formation and gradationally underlies darker garnet-poor biotite-quartz schist of the Palmer Creek Member of the Canton. Age is Late Proterozoic and (or) early Paleozoic.
