Publication_Date: 2001 Title: Geologic maps and structure sections of the southwestern Santa Clara Valley and southern Santa Cruz Mountains, Santa Clara and Santa Cruz Counties, California Edition: 1.0 Geospatial_Data_Presentation_Form: map Series_Information: Series_Name: U.S. Geological Survey Miscellaneous Field Studies Report Issue_Identification: MF-2373 Publication_Information: Publication_Place: Menlo Park, CA Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/mf/2002/2373/ Description: Abstract: This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area. Together with the accompanying text file (scvmf.ps, scvmf.pdf, scvmf.txt), 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: This database and accompanying plot files depict the distribution of geologic materials and structures at a regional (1:24,000) scale. The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking, landslide potential, mineral hazards, seismic velocity, and earthquake faults. In addition, the report contains new information and interpretations about the regional geologic history and framework. However, the regional scale of this report does not provide sufficient detail for site development purposes. In addition, this map does not take the place of fault-rupture hazard zones designated by the California State Geologist (Hart and Bryant, 1997). Similarly, the database cannot be substituted for comprehensive maps that systematically identify and classify landslide hazards.

Use_Constraints: Uses of this digital geologic map should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:24,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:24,000 will not yield greater real detail, although it may reveal fine- scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.

Browse_Graphic_File_Type: PDF Data_Set_Credit: The geology of this area was mapped by R. J. McLaughlin, J. C. Clark, E. E. Brabb, and E. J. Helley between 1988 and 1996; part of the Mt. Madonna quadrangle was mapped by C. J. Colon from 1991-1992. The geology of the New Almaden area is partly compiled from Bailey and Everhart, 1964. The geology along the San Andreas fault is partly incorporated from Sarna-Wojcicki and others, 1975 and from U. S. Geological Survey Staff, 1989. Numerous scientists within the U.S. Geological Survey and from academia, have contributed to this database: Critical paleontologic support was provided by: K. McDougall-Reid and Richard Pierce (deceased), Tertiary benthic foraminifers; D. Bukry, Tertiary nannofossils; J. Barron, Tertiary diatoms; C. Powell, W. Addicott, and J. Vedder, Tertiary macrofossils; W. V. Sliter (deceased), Mesozoic foraminifers; B. Murchey, Y. Isozaki, and I. Hattori, Mesozoic radiolaria; and W. Elder and D.L. Jones, Mesozoic macrofossils. Isotopic data for age and provenance determinations were provided by R. Kistler and D. Champion, Rubidium and Strontium; J. Nakata, D. Sorg and P. Russell, K-Ar and Ar-Ar radiometric ages; and J. Wooden, U-Pb radiometric age. A fission track age investigation, conducted in the map region in 1992-1994 by T. Dumitru, R. BŸrgmann, and Ramon Aerosmith, of Stanford University, in cooperation with the senior author, has contributed substantially to an understanding of the structural history of this area. The senior author (McLaughlin) also wishes to acknowledge the following scientists for their collaborative and cooperative work, that has strongly influenced interpretations of the geology and crustal structure of the map region: R. Jachens, A. Griscom and V. Langenheim (U.S.G.S.), modeling of gravity and aeromagnetic data; R. BŸrgmann (Stanford, now at U.C. Berkeley), geodetic data; C.M. Wentworth and R.G. Stanley (U.S.G.S.), regional geology; R. Wells, D. Ponti, C. Prentice, D. Schwartz, S. Ellen, and K. Schmidt, (all at the U.S.G.S.), and W. Cotton ( W. Cotton and Associates), detailed work on surface deformation and active fault relationships following the 1989 Loma Prieta earthquake. The authors wish to acknowledge the many owners of large land parcels and ranches in rural areas of Santa Clara and Santa Cruz Counties, who have cooperated with these mapping investigations by providing access to their properties and showing interest in the work. We also thank the following private and public agencies for their cooperation in allowing access and gate keys to their properties, including the San Jose Water Company; Mid- Peninsula Open-Space District; and the Santa Clara County Park system. We also wish to thank the California Division of Forestry, particularly CDF Burrel Fire Station of Santa Cruz County, for providing lodging to the senior author (McLaughlin) in the course of mapping investigations. This digital database was compiled in ARC/INFO, a commercial G.I. S.(ESRI). The digital compilation was done using the 1996 version 3.0 of the menu interface ALACARTE (originally published as version 1.0 by Fitzgibbon and Wentworth, 1991). The digitization of geologic contacts, development and integration of various data sets into the digital map database were largely supervised by C. M. Wentworth (1988-1997). Numerous individuals have compiled and edited parts of the digital files for this publication at different times, including T. A. Lindquist (1988), P. Showalter (1989-1990), C. E. Nelson (1994), L. Gerhardt ( 1996), C. R. Randolph, T. E. May, and J. L. Minnick (1996-1998), and Z. C. Valin (1996-2001). The digital geology was initially compiled as a part of the geologic map database for the San Jose, California 1:100,000-scale quadrangle (Wentworth and others, unpublished, 1999) but the maps are herein released at 1:24,000. Geologic mapping was at a scale of 1:24,000, which is therefore the scale of maximum resolution. Enlargement of these maps to scales substantially less than 1:24,000 is here considered inappropriate. Technical reviews of this report were provided by P. Stone ( Western Earth Surface Processes Team, U.S.G.S.) and by M. C. Blake, Jr., (Emeritus). R. Graymer (Western Earth Surface Processes Team, U.S.G.S.) reviewed the database. Technical editing of this report for publication by the U.S. Geological Survey was provided by J. Zigler, and preparation of the database website was by R. Koch and C. Donlin (all at Western Publications Unit, U.S.G.S.). Note: Authorship of the geology of this publication resides in the first five names in the author list in the order given. The last nine names starting with Z.C. Valin, are the digital database authors in the order given. Native_Data_Set_Environment: SunOS, 5.5.1, sun4u UNIX, ARC/INFO version 7.2.1 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: This report has undergone two scientific peer reviews, one digital database review, one review for conformity with geologic names policy, and review of the plotfiles for conformity with USGS map standards. Logical_Consistency_Report: Polygon and chain-node topology present Completeness_Report: The report is intended to describe completely the surficial deposits and bedrock geology at 1:24,000 scale. Geologic information only mappable at larger scale has been omitted. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Well located data items are intended to have a horizontal positional accuracy within .5 mm at 1:24,000 scale, or within 12 meters on the ground. The general positional accuracy of each line in the database is indicated within the LTYPE field in the Arc Attribute Table (see below). Points in the database are generally considered to be well located. The position of each data item is derived from the USGS topographic base map, and therefore additional inaccuracies arising from inaccuracies in the base map may also be encountered.

Title: (field work) Publication_Date: 19992 Source_Contribution: Field work 1991-1992 while graduate intern with U.S. Geological Survey, with field checking by McLaughlin, R.J., in 1996. Source_Citation_Abbreviation: Jové-Colón (1992) Process_Step: Process_Description: Field work was carried out by a variety of investigators over many years, consulting previously published works as well. Geologic linework was scanned, converted to vector data, and edited on-screen to repair errors visible at map scale. Polygon topology was created and each polygon tagged on- screen. Structural information was digitized by hand using a digitizing table. Plotfiles were created in ArcPlot. The databases in this report were compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California), with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). The files are COVERAGE (ARC/INFO vector data) format. Coverages are stored in uncompressed ARC export format (ARC/INFO version 8.0.2). ARC/INFO export files ( files with the .e00 extension) can be converted into ARC/ INFO coverages in ARC/INFO (see below) and can be read by some other Geographic Information Systems, such as MapInfo via ArcLink and ESRI's ArcView (version 1.0 for Windows 3.1 to 3.11 is available for free from ESRI's web site. The digital compilation was done in version 7.2.1 of ARC/INFO with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). The geologic map information was digitized from stable originals of the geologic maps at 1:24,000 scale. The author manuscripts (pen 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 some scanning artifacts visible at 1:24,000 were removed.

Enumerated_Domain_Value_Definition_Source: author Overview_Description: Entity_and_Attribute_Overview: The databases in this report were compiled in ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California). Almost all the attributes in the various attribute tables of the coverages included in the report are set or calculated by Arc/Info. The exceptions are "coveragename"-ID, LTYPE, PTYPE, PTTYPE, STRIKE, and DIP. "coveragename"-ID is required by internal policy to be sequential. This ensures the highest compatibility of our databases with other GISs. Therefore "coveragename"-ID is calculated equal to "coveragename"#, which is a unique, sequential integer assigned by Arc/Info to each data record. LTYPE, PTYPE, and PTTYPE are author added items to the coverage AAT or PAT that are used to describe the type of line (LTYPE), area (PTYPE), or point (PTTYPE) being recorded. All coverages with AAT and PAT present include these items in the data structure. Each has WIDTH 35, OUTPUT 35, TYPE C. STRIKE and DIP are author added items to the coverage PAT that record information about the orientation of planar geologic structures. Both have WIDTH 3, OUTPUT 3, TYPE I. These items are recorded in the tables XX-STR.PAT of the structure coverages. The base map layers are included for visual reference only and contain no data attributes or attribute tables.
