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
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.
