Summary

This data release includes whole rock geochemical data, and uranium-lead isotopic data collected by both Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and Sensitive High Resolution Ion Microprobe-Reverse Geometry (SHRIMP-RG) methods. Whole rock geochemistry was collected by Activation Laboratories in Ancaster, Ontario. LA-ICP-MS data was collected at the PLASMA at the USGS in Denver, Colorado. SHRIMP-RG data was collected at the USGS-Stanford SHRIMP-RG in Palo Alto, California. Rock samples for all methods were collected by Mark Carter of the USGS. The whole rock geochemistry and uranium lead isotopic data constrain the age and origin of rocks in the newly defined Dinwiddie Terrane of eastern Virginia.

Purpose

The data were collected in support of geologic mapping of the Piedmont of eastern Virginia. The data constrain the age and origin of rocks in the newly defined Dinwiddie Terrane. This data release accompanies the planned publication, Redefinition of the Petersburg batholith and implications of crustal inheritance in the Dinwiddie terrane, Virginia, USA, submitted to the journal Geosphere.
