Geochemical data, thin section images, and modal mineralogy of selected bedrock samples in the western half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina

June 24, 2025

This data release contains geochemical data, thin section images, and modal mineralogy from bedrock samples collected in the western half of the Emporia 30’ x 60’ quadrangle, Virginia and North Carolina. The geochemical data comprise whole-rock major oxide and trace element abundances in 246 samples. Pairs of thin section images in plane-polarized light and cross-polarized light are included for 125 samples. Modal mineralogy was obtained by powder X-ray diffraction and the Rietveld method for 97 samples.
