Access Geofacets

By accessing Geofacets, you agree to the Terms and Conditions. Subscribers can use their GSA log in to access the GSA Millennium Edition of Geofacets.


What is Geofacets?

The Geological Society of America now participates in Geofacets, a web-based research tool that offers access to an extensive database of georeferenced geological maps. With intuitive features designed for geoscientists working in upstream oil and gas exploration, it enables users to efficiently and confidently assess a region or basin's geologic characteristics and potential. Users can navigate fluidly between the downloadable maps—available as GeoTiff, KMZ, and more—and the original journal and book content.
