CH-38 bedding-cleavage relations

Detailed Description

An outcrop of greenschist-facies metamorphosed siltstone from the Roanoke Rapids terrane in southeastern Virginia. U-Pb detrital zircon geochronology (conducted by the USGS laser ablation inductively coupled plasma mass spectrometry Lab in Denver) indicates this may be one of the youngest rocks in the eastern Piedmont of Virginia and North Carolina (younger than 300 million years old) and provides important age control as we develop geologic framework models for the easternmost Piedmont in southeastern Virginia and northeastern North Carolina.
