USGS Geochron Database Explorer
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.
