Abstract
Our compilation of geologic mapping over the past 50 years by ourselves and others has resulted in a new look at the Blue Ridge in Georgia. This map at a scale of 1:100,000, on a base compiled from 1:24,000-scale 7.5-min quadrangles, covers the area from the frontal Blue Ridge thrust faults (Talladega-Cartersville, Lost Town Creek-Salacoa, Miller Cove) to the Brevard fault zone. The geologic mapping, including available structure measurements, has been compiled into ESRI’s ArcView. Major features in the map are: the Corbin massif of 1.1Ga basement and its cover; the Murphy marble belt; the Dahlonega fault zone, with its Chattahoochee and Etowah faults; the Dahlonega mining district; the Hayesville fault and thrust sheet; the Allatoona allochthon and fault; and the Tallulah Falls dome, allochthon, and window. Interpretations are ours and may not coincide with those of the original authors/mappers. Part II of the map is from 34o 37' 30" to the North Carolina and Tennessee State Lines.
