Summary

USGS Geochron is a database of geochronological and thermochronological dates and data. The data set contains published ages, dates, analytical information, sample metadata including location, and source citations. The following analytical techniques are represented in the data set: 40Ar/39Ar, K-Ar, U-Th-Pb, Sm-Nd, Rb-Sr, Lu-Hf, fission track, luminescence, U-series in situ, (U-Th)/He, and Re-Os. This data set incorporates data previously hosted in the National Geochronological Database (Sloan and others, 2003), as well as data from published journal articles and ScienceBase data releases. These data are primarily from the United States, but data from other parts of the world are also included. First posted January 2023 (version 1.0 [...]

Purpose

The primary purpose of the USGS Geochron Database is to organize and serve all USGS-generated geochronological data to key stakeholders, scientists, and the public. This data set is applicable to answering fundamental Earth Science questions that require an understanding of the ages of key geologic events and units and the rates of geologic processes. The database is supported by the National Cooperative Geologic Mapping Program’s National Geologic Map Database project and the Geologic Framework of the Intermountain West project and will be managed and served in accordance with the National Geologic Mapping Act of 1992 and its Reauthorizations. The data set as a whole will be updated and expanded semi-annually.
