This database and accompanying plot files depict the distribution of geologic materials and structures at 1:100,000 scale. The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking, landslide hazards, mineral potential, seismic velocity, and earthquake faults. In addition, the report contains new information and interpretations about the regional geologic history and framework. However, the scale of this report does not provide sufficient detail for site development purposes. In addition, this map does not take the place of fault-rupture hazard zones designated by the California State Geologist. Similarly, although numerous landslides are mapped, the database does not identify or delineate all landslides in the map area or their present states of activity.

Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Various logical accuracy tests were conducted. They include: Deposional contacts only separate different units; All concealed contacts or faults separate only identically tagged units; All adjacent terranes are in fault contact with each other (no depositional contacts); All water bodied are fully surrounded with lines tagged "water boundary"
Are there legal restrictions on access or use of the data?
