Arthur Merschat
Arthur Merschat is a Research Geologist at the USGS Florence Bascom Geoscience Center.
"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."
