Description:

Abstract:

This digital map database, which is compiled from previously published and unpublished sources combined with new mapping, represents the general distribution and identity of bedrock in Contra Costa County, California.

Purpose:

The purpose of this report is to provide to the public a digital geologic map database, and together with the accompanying text file (ccgeo.txt), it provides current information on the stratigraphy and structural geology of the area covered.

Data_Set_Credit:

J. Ross Wagner, Montgomery Watson Consultants, Walnut Creek, kindly shared his extensive and high quality unpublished geologic maps covering the area from Pinole to San Ramon (see ccsource.txt). Thomas D. Barrow, President of Exxon, graciously released unpublished geologic mapping and paleontologic information collected by Howard S. Sonneman and John R. Switzer, Jr. covering most of the central and all of the eastern part of the county. We are grateful to James R. LeCompte who compiled these maps and other data in the 1970's. This drafted copy was scanned and initially edited and tagged by Maureen A. Kelly in consultation with Carl M. Wentworth. We are also grateful to Kristin R. McDougall, William V. Sliter, David Bukry, John A. Barron, and William P. Elder for paleontologic determinations, Marvin A Lanphere and Robert J. Fleck for the determination of the age of volcanic rocks, and Andrei M. Sarna-Wojcicki for correlation of volcanic tuffs that helped establish the stratigraphic sequence and structural complexity of the geologic units. Alvin A. Almgren, Unocal (retired) reviewed early versions of this map and provided much new information. Philip J. Stuecheli, Geotechnical Engineering Consultants, provided access and subdivision maps for an area under construction in Clayton. Tim D. Bray, consultant and Prof. Raymond Sullivan, San Francisco State Univ., arranged for access to cores and other geologic information in the Keller Canyon landfill area south of Pittsburg. David J. Gross, Woodward-Clyde Consultants, provided geologic maps and arranged for access to cores in the Los Vaqueros Dam area near Byron. Laurel Collins helped provide access to lands owned by the East Bay Regional Park District. Larry J. Dickerson and John M. Parker provided extensive support in the field. Carl Wentworth and Geoff Phelps provided assistance with Alacarte and ARC/INFO.

Native_Data_Set_Environment: ARC/INFO version 6.1.1

Data_Quality_Information:

Logical_Consistency_Report:

This map represents an integration of the published and unpublished geologic maps of several previous workers (see Sources of Data in ccsource.txt) and more than 1000 man hours of new geologic mapping and field checking by us. The data are released in a preliminary digital form to provide an opportunity for staff from governmental agencies, consultants, teachers, and other users to have this geologic map long before the final map is published.

Completeness_Report:

The faults represented in this database are not intended to show hazards at any specific site, or to take the place of fault-rupture hazard zones designated by the California State Geologist (Hart, 1988).

Process_Step:

Process_Description:

The geologic map information was digitized from stable originals of the geologic maps mostly at 1:62,500 scale (geology in the San Quentin quadrangle was scanned at 1:24,000 scale). The author manuscripts (ink on mylar) were scanned using a Tektronix 4991 monochrome scanner with a resolution of 304.8 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 a contact or fault as appropriate, and scanning artifacts visible at 1:50,000 were removed.
Base Map layers were prepared from scale-stable printing negatives of the U.S. Geological Survey Napa (1983 edition), Lodi (1993 edition), Stockton (1989 edition), and San Francisco (1978 edition) 1:100,000 topographic maps. Scanned and vectorized images were transformed from scanner coordinates to projection coordinates with digital tics placed by hand at map corners. The images were then trimmed interactively by hand using ALACARTE to conform to the area of the geologic coverages, and the various portions were combined. Small mismatches at the boundaries caused by slight differences in the original scans remain in the three base map coverages. These base map layers are digital images but no information other than location is attached to the lines.
