Appalachian Basin Geologic Mapping Project

The Appalachian Basin Geologic Mapping Project performs geologic mapping at local and regional scales, and geologic research in The Valley and Ridge and Appalachian Plateaus physiographic provinces. These provinces include parts of 11 states and mainly borders the Blue Ridge / Piedmont and North Interior Lowlands Provinces. Two states have Valley and Ridge geology only (GA, NJ), two have...

Blue Ridge and Inner Piedmont Geologic Mapping

The Blue Ridge and Inner Piedmont Geologic Mapping Task (BRIP) is the western focus of geologic mapping and framework studies of the Piedmont and Blue Ridge Project. BRIP will conduct modern geologic mapping and geologic framework studies in the Wytheville, Hickory and Boone 30x60-min. sheets. Collectively, the objectives of BRIP are to (1) characterize the geologic framework of the Blue Ridge...

Coastal Basement Geology of the Southeastern U.S. Project

This project, centered on South Carolina and Georgia, extends coastal-basement geologic mapping and related research south of a geologic map in production for pre-Cretaceous rocks beneath the Atlantic Coastal Plain from Virginia to southern New Jersey, and adds detail to a national-scale basement domain map constructed to delineate mineral-resource...

Piedmont Geology Along the Southeastern Fall Zone, Virginia and North Carolina

This task within the USGS NCGMP Piedmont-Blue Ridge Project aims to fill the void in geologic map coverage along the Fall Zone in southeastern Virginia and northeastern North Carolina, and forge strong cooperative ties within the NCGMP by combining resources across all three Program components by supporting DMME and NCGS STATEMAP and UNC–W EDMAP components with targeted geologic mapping and...

Geologic Framework for Seismic Hazards in Central Virginia

The Central Virginia seismic zone (CVSZ) comprises an area of ~13,000 km2 in the central Virginia Piedmont; seismicity in this zone is relatively frequent, but generally mild in magnitude. The August 2011 event was the largest temblor recorded in the CVSZ since the development of modern seismic monitoring and highlighted how little we actually know about the CVSZ, including: 1) the...
