Detrital zircon U-Pb data for reconnaissance characterization of strata across the Intermountain West region of the United States

This document describes sedimentary rock samples and their associated detrital zircon U-Pb data that were collected to support geologic mapping and research initiatives within the context of the Geologic Framework of the Intermountain West Project. The data characterize the age and/or provenance of Neoproterozoic to Miocene strata exposed across the Intermountain West region of the United States, with outcrop locations distributed across parts of California, Colorado, Montana, Nevada, New Mexico, and Utah. Most detrital zircon U-Pb data presented herein were acquired at the University of Arizona LaserChron Center (Tucson, AZ) between 2019 and 2024; a small subset of data was acquired at the U.S. Geological Survey Plasma Lab (Lakewood, CO) in 2021.
