Framework Mapping

The Atlantic Subsurface Stratigraphic Initiative (ASSI) is a project with an interdisciplinary group of scientists focused on documenting the Cretaceous and Cenozoic subsurface geology of the Salisbury Embayment across Maryland and Virginia. Data generated by ASSI is crucial for resolving stratigraphic issues across state boundaries and regions. By working closely with state geologic surveys, ASSI...

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. Only one state has Valley and Ridge geology (NJ), two have Appalachian...

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 and...

The Piedmont and Blue Ridge Project is a geologic mapping project supported by the USGS National Cooperative Geologic Mapping Program. The Piedmont Blue Ridge Project aims to understand the geologic framework and tectonic evolution of terranes and basins in the Appalachian Piedmont and Blue Ridge, and their significance for water, mineral and energy resources, natural hazards, and engineering...

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 prospectivity. Plans include efforts to build on...

The Central Virginia seismic zone (CVSZ) comprises an area of ~13,000 km 2 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 regional...
