Helen Member of Canton Formation. Here named, is in the Dahlonega area, Georgia, and was previously mapped as the Carolina Gneiss by Keith (1909). [It is incorrectly stated by German (1985) that Gillon (1982) named these rocks the informal Helen sequence. Gillon's (1982) informal Helen group was formally named the Helen Group by Nelson and Gillon (1985), a usage that is consistent with Gillon's original definition and should take precedence over the usage of German (1985) of Helen Member of the Canton Formation.] The Helen Member consists of biotite-plagioclase-quartz gneiss and biotite-muscovite-quartz schist containing garnet. Is in sharp contact with the Chestatee Member (new name) of the Canton; grades into the Univeter (new name) and Tallulah Falls Formations to the southeast and the Palmer Creek Member (new name) of the Canton and the Coweeta Group to the northwest. Its boundaries are defined as the last occurrence of interlayered metagraywacke and biotite-muscovite-quartz schist. Age is Late Proterozoic and (or) early Paleozoic.
Named from town of Helen, White Co., GA.
