NOTE: CALIFORNIA IS A PROJECT UNDER CONSTRUCTION, COMMENCING JULY 28, 2005. EXISTING LOCALITY FILES WILL BE UPDATED FIRST, THEN ADDITIONAL LOCALITIES WILL BE FILLED IN. Chet Lemanski & Dave Von Bargen.

NOTE: The bibliography for California mineralogy is very extensive. Only references pertaining to the entire state are presented here. Specific references may be found at each individual locality file.

According to Bulletin 189 (Murdoch & Webb, 1966, pp. 543-545), mining districts in California apparently have had no formal recognition by statute at the state level. Study of the written record; however, suggests that many early geologists, mining engineers, and prospectors expected that formal requirements would be legislated, and, in anticipation, terms like "Bonanza Mining District" were coined and widely used in early literature. A list of the mining districts is presented in USGS Bull. 507 and is incorporated into another list or data table in Bull. 189, which provides the USGS "official" name as well as synonyms, if any, county of location and nearest "permanent" town or settlement for each.

There are 3 Meridians used in the Township and Range values for California. These are: the Humboldt Meridian (abbreviated as "HM" in this database)(extreme NW corner of the state); the Mount Diablo Meridian (abbreviated as "MDM" in this database)(center and northern parts of the state); and the San Bernardino Meridian (abbreviated as "SBM" in this database)(southern portions of the state). NOTE: The T&R values for fractions of a section are read from the right to left (e.g.: the N½SE¼NW¼ is the NW quarter of the section, the SE quarter of that, and then the N half of that segment).
