Summary

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, [...]

Purpose

The geologic map database of the Charlotte 1 degree × 2 degrees Quadrangle of North Carolina and South Carolina is intended to serve as a foundation for applying geologic information to problems involving land use decisions, groundwater availability and quality, earth resources such as natural aggregate for construction, assessment of natural hazards (earthquakes), and engineering and environmental studies for waste disposal sites and construction projects. The database and associated geologic map improve the understanding of the bedrock geology in the Blue Ridge and Piedmont geologic provinces, establishes a modern framework for 1:250,000-scale bedrock geologic mapping in North Carolina and South Carolina.
