Outcrop of Blue Quartz-Bearing Granite, Roanoke Rapids

Detailed Description

An outcrop of blue quartz-bearing granite within the Roanoke Rapids terrane.  Sensitive high-resolution ion microprobe U-Pb geochronology will precisely determine the age of this rock (conducted by the USGS-Stanford SHRIMP Lab in Menlo Park) and will provide critical geochronologic age control as a geologic framework model is developed and complied for the easternmost Piedmont in southeastern Virginia and northeastern North Carolina.
