Georgia, the largest state east of the Mississippi River, is naturally divided into 5 topog­raphic/geologic provinces, from northwest to southeast: the Cumberland Pla­teau, Valley and Ridge, Blue Ridge, Piedmont, and Atlantic and Gulf Coastal Plains provinces. Most of these prov­inces are separated by faults or fault zones. The Cumberland Plateau province is separated from the Valley and Ridge province by to­pography, though there are lithologic/facies differences as well; the Valley and Ridge province is separated from the Blue Ridge by the Cartersville-Talladega fault/fault zone; the Blue Ridge province is separated from the Piedmont province by the Brevard fault zone. The Coastal Plains overlie the Valley and Ridge, Pied­mont, and Blue Ridge provinces on a major unconformity.
