Summary

In situ geochemical data were obtained for pyrite crystals and native gold from two distinct vein sets in the Grass Valley gold district, California. Samples of the N-S veins were collected underground at the Empire Mine State Historic Park and samples of the E-W veins were collected from drill core provided by the Idaho-Maryland Mining Corporation in 2008. These geochemical data were analyzed to better understand paragenesis of quartz veins in orogenic gold deposits. Data includes electron probe microanalysis (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) chemistry and LA-ICP-MS sulfur isotope values for pyrite crystals, and EPMA geochemistry of native gold grains found within the orogenic gold [...]
