Preliminary Integrated Geologic Map Databases of the United States

These Open-File Reports represent preliminary parts of a larger planned series of integrated geologic databases that will ultimately be available for the entire United States.  These interim versions are being released now in order to provide ready access to standardized geologic data for use in regional analyses and to meet product distribution goals. The final compilation of these state databases will allow integration of the data that are found on state-scale geologic maps, presented in a uniform database structure.
