The Blue Ridge belt in northwestern North Carolina and northeastern Tennessee is composed chiefly of 1,000-million to 1,100-million-year-old metamorphic and plutonic rocks that have been thrust many miles northwestward across unmetamorphosed Cambrian(?) and Cambrian sedimentary rocks of the Unaka belt. The Blue Ridge thrust sheet is rooted on the southeast along the Brevard zone, a zone of strike-slip faulting along which metamorphic and plutonic rocks of the Inner Piedmont belt are juxtaposed with rocks of the Blue Ridge. Near the southeastern edge of the Blue Ridge belt, the Blue Ridge thrust sheet is breached by erosion, and the rocks beneath are exposed in the Grandfather Mountain window, which is 45 miles long...

The geodatabase for the Charlotte 1 degree × 2 degrees quadrangle by Goldsmith and others (1988) was compiled in the Geologic Map Schema (GeMS). The geologic map extends across four lithotectonic belts of the Piedmont from the Coastal Plain and Wadesboro Triassic basin on the east to the Blue Ridge belt in the vicinity of the Grandfather Mountain window on the west. The Wadesboro Triassic basin contains arkosic sandstone, siltstone and conglomerate unconformably overlain by small inliers of late Cretaceous Coastal Plain sediment of the Middendorf Formation (?). The Blue Ridge, Inner Piedmont, Kings Mountain, Charlotte, and Carolina Slate belts consist of different Mesoproterozoic to Late Paleozoic metamorphosed...
