Published by U.S. Geological Survey | Department of the Interior | Catalog Last Checked: May 05, 2026 at 09:08 PM | Dataset Last Updated: October 20, 2022 at 12:00 AM
This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data to determine the ages of Challis igneous rocks in the Thunder Mountain volcanic field and dikes west of the volcanic field, especially in and near the Stibnite-Yellow Pine mining district, ID. These efforts were made to help understand the stratigraphy and lithologic characteristics of the Challis igneous rocks by determining their absolute ages.
