<DIV STYLE="text-align:Left;"><DIV><P><SPAN>This edition of the Geologic Map of California was prepared in recognition of the California Geological Survey's 150th Anniversary. It is an all-digital product built on the original compilation of C.W. Jennings published in 1977, with some additions and modifications. The Geologic Map of California presents an overview of the geology and structure of the state. It represents the geologic features that one would find on a visit to any locality in the state. The restraints of scale limit the detail that can be shown, but the most important geologic features are portrayed. The distribution of the major rock types and the major structural elements are shown with sufficient detail to be useful for many purposes. Please see the map pamphlet (included in this digital package as a PDF document) for further information.</SPAN></P></DIV></DIV>

Some simplification was necessary to make a legible map at 1:750,000 scale.
Data were checked against the original source materials by the author(s). Although every effort was made to maintain and ensure the accuracy of this dataset, several potential sources of error remain. Users of this dataset should be aware of the difference between precision and accuracy. While digital data can be reproduced precisely at any scale, the accuracy of the data remains constant.
Most or all of the data in this map were digitized from hard copy maps. Users of this dataset should be aware of the inherent potential for error in the processes of plotting, drafting, and digitization. For example, a plotting error of one line width equal to 0.5 mm at 1:750,000 scale could cause a location error of approximately 375 meters on the ground.

Map No. 2
Correction of Spatial Errors: During preparation of the original digital data set, which included digitizing and editing scanned mylar copies of the Jennings 1977 publication plates, it was noted that the north and south parts of the map were presented at slightly different scales (Saucedo and others, 2000). This inconsistency was likely inherited during the preparation of the original base map used in printing the 1977 edition. The base was a composite of the north and south halves of the 1:500,000-scale U.S. Geological Survey state map series, photographically reduced to publication scale (1:750,000), and spliced together. Although an attempt was made to correct this problem while georeferencing the scanned image, spatial errors of up to 1 km remained in the original data set, especially near the seam between the north and south halves and along the coast. In an attempt to eliminate or at least minimize the spatial error, the digital file was warped using features common to the geologic map and a precisely registered hydrologic data set. Features such as the coastline, and lakes were used for this purpose. The resulting file still contains location errors but they have been reduced significantly and are largely within the National Map Accuracy Standards for this scale of map.

Modifications to Faults: The 2010 edition of the Geologic Map of California includes modifications to the fault traces depicted on the original map by Jennings (1977). Many faults have been added (Figure 1, in pamphlet), modified, or deleted (Figure 2, in pamphlet) for consistency with the 2010 edition of the Fault Activity Map of California (Jennings and Bryant, 2010), which is a companion to this geologic map. The new version of the Fault Activity Map of California presents a much more detailed depiction of faults in California than previous versions. Faults active in the Quaternary (2.6 Ma) were digitized from their original sources in order to preserve as much of the original detail as possible. The faults in the offshore region of the geologic map were replaced with un-simplified fault traces from the new fault map. However, due to the complexity of the onshore geologic data depicted on the Geologic Map of California, it was not technically feasible to incorporate the new detailed fault data in its entirety. A comparison of the datasets was made and numerous fault traces identified as either poorly mapped or mislocated on the original geologic map were replaced with simplified fault traces based on the new fault map (Appendix A, in pamphlet). In addition, several faults that have been mapped since the compilation of the original geologic map were also identified and added, and traces no longer believed to be faults were removed. Although the modification of faults in some areas necessitated the modification of bedrock geology adjacent to those faults, the distribution of bedrock geologic units compiled by Jennings (1977) has otherwise not been updated. In general, the Quaternary faults shown in the onshore region of this map are intended to be a simplified representation of the faults depicted on the Fault Activity Map.

Modifications to Quaternary Alluvium: The depiction of Quaternary geologic units on the original map by Jennings (1977) was simplified by the author who noted that "various surficial deposits of Quaternary age are lumped into the unit 'Q'." Since Jennings' work, subdivisions of these deposits have been found to have very different potential for liquefaction and for amplification of seismic shaking. Relative age of Quaternary alluvial fan deposits have also been found to correlate with potential for flooding. Since these units are important for evaluation of geologic hazards, the 2010 update of the geologic map includes a subdivision of Jennings "Q" into younger alluvium "Q" and older alluvium "Qoa" (Figure 3, in pamphlet). Boundaries of older and younger alluvium were digitized from the 1:250,000 scale Geologic Atlas of California, compiled from 1958 to 1974 and the Regional Geologic Map series, compiled from 1981 to 1992. These boundaries were then incorporated into the geologic map and used to subdivide the preexisting "Q" polygons.
