USGS Geochron Database Explorer
March 30, 2023
USGS Geochron is a database that includes USGS-generated geochronology data. It has incorporated data from the legacy USGS National Geochronology Database, and our team (Geologic Framework of the Intermountain West Project, National Geologic Map Database, Argon Geochronology Project) has also compiled significant amounts of new data. The webmap is sortable by 40Ar/39Ar, Fission Track, K-Ar, Lu-Hf, Rb-Sr, Sm-Nd, U-Th-Pb In-situ, and U-Th-Pb TIMS methods.

USGS Geochron: A database of USGS geochronological and thermochronological data
The U.S. Geological Survey (USGS) has developed an updated geochronology database (USGS Geochron) to include geochronology summary and analytical data created or funded by the USGS.
Argon Geochronology
This project supports the USGS argon geochronology laboratory in Denver. The USGS 40Ar/39Ar geochronology laboratory is a state-of-the-art research facility for determining absolute ages of minerals and rocks. The 40Ar/39Ar laboratory contributes critical geochronology to individual USGS research projects and to partners in academia and other Federal agencies. This laboratory develops methodology...
Geologic Framework of the Intermountain West
The Geologic Framework of the Intermountain West (IMW) Project conducts 1:24,000- to 1:100,000-scale geologic mapping to support framework geologic investigations. The IMW project is prioritizing development of a seamless, integrated geologic map database in targeted areas of the Intermountain West region of the United States that host substantial mineral, energy, water, and industrial material...
Serving the U.S. Geological Survey’s geochronological data
Geochronological data provide essential information necessary for understanding the timing of geologic processes and events, as well as quantifying rates and timescales key to geologic mapping, mineral and energy resource and hazard assessments. The USGS’s National Geochronological Database (NGDB) contains over 30,000 radiometric ages, but no formal update has occurred in over 20 years...
