Together with the accompanying text file (cdbegeo.txt or cdbegeo.ps), it provides current information on the geologic structure and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:24,000 or smaller. Purpose: To provide current information on the geologic structure and stratigraphy of a geologic map of the Cordelia and the northern part of the Benicia 7.5' quadrangles, California.

Browse_Graphic_File_Type: PDF Data_Set_Credit: We are grateful to the following U.S. Geological Survey paleontologists who have examined our fossils and provided ages necessary to establish the stratigraphic sequence and structure: David Bukry (Cretaceous and Tertiary nannoplankton), Kristin McDougall (Tertiary foraminifers), William Sliter (deceased - Cretaceous and Eocene foraminifers), John Barron (Tertiary diatoms), Charles Powell II (Tertiary mollusks), and Bonita Murchey (Mesozoic radiolaria). We are also very grateful to managers and staff of Chevron, EXXON, UNOCAL, ARCO, and Shell Petroleum Companies who have provided reports, maps, picked slides, and residues for about 25,000 microfossil localities in the San Francisco Bay Region. Carl Wentworth kindly provided advice on digitizing and editing procedures. Ed Helley provided materials and advice on Quaternary units. Native_Data_Set_Environment: The digital compilation was done in version 7.0.4 of ARC/INFO with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). Data_Quality_Information: Logical_Consistency_Report: This map database represents the integration of previously published and unpublished maps by several workers and new geologic mapping and field checking by the authors.

The author manuscripts (pencil on mylar) were scanned using a Altek monochrome scanner with a resolution of 800 dots per inch. The scanned images were vectorized and transformed from scanner coordinates to projection coordinates with digital tics placed by hand at quadrangle corners. The scanned lines were edited interactively by hand using ALACARTE, color boundaries were tagged as appropriate, and scanning artifacts visible at 1:24,000 were removed. Base maps Base Map layers were prepared from Digital Raster Graphic (DRG) versions of standard U.S. Geological Survey 7.5 minute quadrangles obtained from the U.S. Geological Survey Mapping Division Website for the San Francisco Bay region (http://bard.wr.usgs.gov). Please see the website for more detailed information about the original DRGs. The DRGs were converted to ARC/INFO GRIDs using the imagegrid command. The GRIDS were then edited by us to remove area fill colors (for example urban pink and purple, forested green, and water blue). The edited GRIDs were then combined with GRIDs produced from the geologic map coverages and overlain with vector data to produce the final cartographic product presented in cdbeplt.ps and cdbeplt.pdf. Because the base map digital files (DRGs) are already available at the website mentioned above, they are not included in the digital database package.
