Results of the study are described and interpreted in Lund and others (2018). Data included are U-Pb sensitive high-resolution ion microprobe (SHRIMP) geochronology for quartz porphyry dikes, 40Ar/39Ar thermochronologic data for biotite, hornblende, and K-feldspar from Butte granite country rock, and 40Ar/39Ar thermochronologic data for white mica and K-feldspar from alteration zones around lode veins. Also included are backscatter electron (BSE) and panchromatic cathodoluminescent (CL) imagery of minerals from samples dated by 40Ar/39Ar.
