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.
We are now compiling into a single database all USGS-related published geochronologic data. We have extended the scope to include similar data generated by our State geological survey partners via the STATEMAP program. USGS Geochron is supported by, and will be managed and served by, the Geologic Framework of the Intermountain West Project and the National Geologic Map Database, in accordance with the National Geologic Mapping Act of 1992 and its Reauthorizations.
Geochronologic data are integral to geologic mapping and are utilized by researchers, stakeholders, and the science-interested public to study the Earth’s lithosphere and landscapes and to manage resources and natural hazards. To address these questions, scientists at the United States Geological Survey (USGS) and State geological surveys have generated a significant amount of geochronologic data. Our team has developed a new centralized database of USGS-generated and -funded geochronologic and thermochronologic data. These data span analytical techniques from Quaternary methods, such as optically stimulated luminescence and U-Th series, to long-lived isotopic systems, such as the U-Th-Pb, Sm-Nd, and 40Ar/39Ar methods. The included methods will continue to grow and reflect the diversity of USGS analytical labs and projects.
There are currently 4 ways to access the current data. All four methods access the same source data.
- Database explorer: interactive, web experience with point-and-click access to geochronology information, as well as the ability to download data files for selected areas.
- Database downloader: map-based downloader with ability to download data from selected areas.
- Data release: contains all data in .csv files, with metadata and data dictionary files. The explorer and downloader both access data release files
- GIS Hosted Feature Layer: view data using GIS software using “add data from path” function.
