Summary:
The Chestatee Member of the Canton Formation, here named in the Dahlonega area, GA, was previously mapped as the Roan Gneiss by Keith (1909). It consists of amphibolite, hornblende-plagioclase gneiss, muscovite-biotite-quartz-plagioclase gneiss, and muscovite-pyrite-plagioclase-quartz gneiss. The Chestatee is in sharp contact with metagraywacke of the Helen Member of the Canton to the southeast and in fault contact with biotite-quartz schist of the Palmer Creek Member of the Canton to the northwest. Age is Late Proterozoic and (or) early Paleozoic.
