Brabb Publication_Date: 1995 Title: Geologic map of the Hayward fault zone, Contra Costa, Alameda, and Santa Clara Counties, California: A digital database Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: U.S. Geological Survey Open-File Report Issue_Identification: 95-597 Online_Linkage: http://pubs.usgs.gov/of/1995/of95-597/ Description: Abstract: This digital map database, compiled from previously open- filed U.S. Geological Survey reports (Graymer and others, 1994, Graymer, Jones, and Brabb, 1994) and unpublished data, represents the general distribution of rocks and faults in the Hayward fault zone. As described in this report, the Hayward fault zone is a zone of highly deformed rocks which trends north 30 degrees west from an area southeast of San Jose to the San Pablo Bay, and ranges in width from 2 to 10 kilometers. Although historic earthquake activity has been concentrated in the western part of the zone, the zone as a whole reflects oblique right-lateral and compressive deformation along a significant upper crustal break over the past 10 million years or more. Together with the accompanying text file (hfgeo.txt), the database provides current information on the distribution and description of faults and rock types within the fault zone. In addition, the text file discusses the development of the fault zone in the past 10 million years, the relationship of the Hayward and Calaveras fault zones, and the significance of the creeping strand of the Hayward fault (as most recently defined by Lienkaemper, 1992). Purpose: The purpose of this report is fivefold. 1) to demonstrate the short history of the creeping strand and to describe the structural history of the fault zone as a whole; 2) to illustrate potentially active strands within the Hayward fault zone in addition to the creeping strand defined by Lienkaemper; 3) to describe structures related to the Hayward fault zone including compressive structures; 4) to show possible Hayward - Calaveras fault connections in addition to that proposed by Andrews and others; 5) to describe rock types involved in the Hayward fault zone.

Browse_Graphic_File_Type: JPEG Data_Set_Credit: All of the geologic mapping for the Hayward fault zone is new, but we acknowledge our debt to previous workers who established the geologic framework. Data sources for geologic mapping in the fault zone within Contra Costa County are provided by Graymer, Jones, and Brabb (1994). In Alameda and Santa Clara Counties, the geologic reports by Radbruch (1969), Case (1968), Graymer and others (1994), Robinson (1956), Hall (1958), and Crittenden (1951) are especially relevant. Preliminary geologic maps by T.W. Dibblee of most of the 1:24,000 quadrangles are available in Open-File Reports of the U.S. Geological Survey (see references). The map and report by Lienkaemper (1992) provided some of the lines for the creeping strand of the Hayward fault, and they contain many references to previous work. Several students have done theses in the area; the ones by Haltenhoff (1978), Whiteley (1978), and Prowell (1974) are especially pertinent.
