Arthur Merschat
Biography
I have worked for the USGS from 2006 until present, a period that includes a SCEP appointment during my Ph.D., and as a Research Geologist (2009–present). My research is focused on (1) the structure and tectonics of the Appalachian orogen; (2) the provenance of the different crystalline terranes of the Blue Ridge and Piedmont; and (3) the thermochronologic evolution of the orogen. I have integrated geologic mapping, structural analysis, SHRIMP U-Pb geochronology, petrology, and geochemistry into my research. Currently, I am involved with bedrock geologic mapping projects in the Blue Ridge — Mount Rogers area, VA–NC–TN, and Roan Mountain, NC–TN — and in New England — southwest NH and parts of VT.
Science and Products
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...
Piedmont and Blue Ridge Project
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/...
