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 and deformed stratified, and meta-igneous and igneous rocks. The belts of rocks are foliated and folded. Regional structures within the map include the Grandfather Mountain window, Brevard fault zone, Kings Mountain shear zone, Eufola fault zone, and Gold Hill and Silver Hill shear zones. These rocks and structures are cut by Triassic to Jurassic diabase dikes. Surficial deposits were not compiled in the database.
