Maps
The Mineral Resources Program conducts geologic mapping to characterize and assess mineral resources across California. In recent years, most mapping activities have been carried out as part of Earth MRI projects. Links to recent mapping products are provided below. For geologic maps in Mineral Land Classifications, please visit the Mineral Land Classification Page or the CGS Publications Request Page.
Data
