Outcrop of Quartzite Within the Roanoke Rapids

Detailed Description

An outcrop of quartzite within the Roanoke Rapids terrane near Coleman Lake.  Laser ablation inductively coupled plasma mass spectrometry U-Pb geochronology on detrital zircon grains within this unit (conducted by the USGS LA-ICPMS Lab in Denver) will provide critical and precise geochronologic age control as a geologic framework model is developed and compiled for the easternmost Piedmont in southeastern Virginia and northeastern North Carolina.
