contact | Boundary between two mapped units that retains the original depositional or intrusive relationship (i.e. not faulted). The contact may or may not have been observed, but the location is constrained to be within about 2 mm at map scale (1:50,000) or within about 100 meters on the ground. |
fault | Structural boundary between mapped units or structural discontinuity within a mapped unit that has experienced relative offset between the rock bodies on either side of the fault. The fault has been observed or is closely constrained, so it is well-located as described in Positional_Accuracy. |
fault, approximately located | Structural boundary between mapped units or structural discontinuity within a mapped unit that has experienced relative offset between the rock bodies on either side of the fault. The fault has not been observed, so it is not well-located as described in Positional_Accuracy, but the location is constrained to be within about 2 mm at map scale (1:50,000) or within about 100 meters on the ground. |
fault, concealed | A planar surface of rupture along which geologic units have been fractured and then displaced |
fault, inferred | Structural boundary between mapped units or structural discontinuity within a mapped unit that has experienced relative offset between the rock bodies on either side of the fault. The fault has not been observed, so it is not well-located as described in Positional_Accuracy, but the location is constrained to be within about 5 mm at map scale (1:50,0000) or within about 250 meters on the ground. The existence of the fault is inferred from structural and stratigraphic relationships observed elsewhere. |
fault, questionable | Structural boundary between mapped units or structural discontinuity within a mapped unit that has experienced relative offset between the rock bodies on either side of the fault. The fault has not been observed, and its existence is questionable |

This database and accompanying plot files depict the distribution of geologic materials and structures at 1:50,000 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.

Well-located data items are intended to have a horizontal positional accuracy within 1 mm at 1:50,000 scale, or within 50 meters on the ground. The relative positional accuracy of each line in the database is indicated within the LTYPE field in the Arc Attribute Table (see below). Points in the database are generally considered to be well located. The position of each data item is derived from the USGS topographic base map, and therefore additional inaccuracies arising from inaccuracies in the base map may also be encountered.
The report is intended to describe completely the surficial deposits and bedrock geology at 1:50,000 scale. Geologic information only mappable at larger scales has been omitted.
This data set is a network coverage containing attributed arcs, polygons, label points, location of volcanic vents, and structural data points. All polygons and arcs have been attributed, and are consistent with source information. Faults, stratigraphic contacts, and other linear features are represented as arcs. When a fault is also a stratigraphic, only a single arc is present. Dangling arcs representing faults exist but no dangled stratigraphic contacts exist.
Are there legal restrictions on access or use of the data?
- Access_Constraints: None
- Use_Constraints:
- Uses of this digital geologic map should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. This database was edited for a nominal scale of 1:50,000; higher resolution information is not present in the dataset. Plotting at scales larger than 1:50,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.
