The map is a new geologic compilation that is based on extensive previous work by many authors and a great deal of new mapping, largely at 1:24,000, much of which is previously unpublished. This report presents the preliminary geologic map of the San Jose 30 x 60-minute quadrangle at a scale of 1:100,000, and consists of a spatial database of nine layers, two colored map sheets (geologic map and correlation diagram), and a descriptive text.

Much of the material was initially fitted to 1:24,000 topography in polyconic or California State Plane (zone 4) projection. These were converted to UTM (see below), and the larger resulting departures from the 1:100,000 base then refitted to that base. Some of the most detailed areas, particularly in the Santa Cruz Mountains and the Del Puerto Ophiolite, were simplified for smaller scale presentation. The geology layers for the 32 individual quadrangles were assembled into a single layer for the 1:100,000 map area and interior quadrangle boundaries were removed. The locations and identities of tectonic blocks in the Diablo Range were similarly compiled, both from mapped points and from areas too small to show at scale (diameter less than 100 m) or representing aggregates of blocks. The resulting spatial database and standard symbol sets in ALACARTE were then used to prepare the colored geologic map image presented here. Some of the details in the spatial database, although retained in the 1:100,00 image, are too small for legible portrayal at that scale.
