Summary

These data are for a multidisciplinary study of dikes, country rock, and alteration systems, Butte, U.S.A. Results of the study are described and interpreted in Lund and others (2018). Data included are U-Pb 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. These data are shared to meet open data requirements for interpretive report: Lund, K., McAleer, R.J., Aleinikoff, J.N., Cosca, M.A., [...]

Purpose

The study provides age data to test ore-deposit models for relations between stockwork Cu-Mo and Ag-Zn-Cu lodes at Butte, Montana, by undertaking a comprehensive district-wide, SHRIMP U-Pb study of dike emplacement ages combined with 40Ar/39Ar study of host rock cooling and reheating as well as 40Ar/39Ar study of muscovite in alteration adjacent to lodes.
