Publication_Date: 2000 Publication_Time: Title: Geologic map and map database of the Spreckels 7.5-minute quadrangle, Monterey County, California Edition: 1.0 Geospatial_Data_Presentation_Form: geologic map Series_Name: U.S. Geological Survey Miscellaneous Field Studies Report Issue_Identification: Publication_Information: Publication_Place: Menlo Park, CA Publisher: U.S. Geological Survey Other_Citation_Details: Online_Linkage: http://pubs.usgs.gov/mf/2001/2349/ Description: Abstract: This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area.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 (skmf.txt, skmf.pdf, or skmf.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: This database and accompanying plot files depict the distribution of geologic materials and structures at a scale of 1:24,000. 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 used to accurately identify or delineate landslides in the region. Supplemental_Information: Procedures_Used: 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 in either GRID (ARC/INFO raster data) format or COVERAGE (ARC/INFO vector data) format. Coverages are stored in uncompressed ARC export format (ARC/INFO version 7.x). 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: http://www.esri.com). The digital compilation was done in version 7.1.1 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 a stable original of the geologic map at 1:24,000 scale. The author manuscript (pen on mylar) was scanned using a Altek monochrome scanner with a resolution of 800 dots per inch. The scanned image was 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.

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.

Wagner also coordinated the work of Sarah E. Watkins (CDMG), who digitized the geologic map for incorporation into the geologic map of the Monterey 1:100,000-scale quadrangle, which is in preparation. Andrei Sarna-Wojcicki (USGS) analyzed and correlated Miocene ash beds from the quadrangle. Charles Powell, II (USGS) identified and interpreted mollusks collected from the quadrangle by Brabb and Clark. He also examined and interpreted mollusks at the California Academy of Science collected by Bowen and at the Museum of Paleontology, University of California, Berkeley that had been collected and reported by Herold (1935). Kristin McDougall (USGS) identified and interpreted Miocene foraminifers. Victoria Langenheim (USGS) and Robert Jachens (USGS) kindly provided unpublished gravity and aeromagnetic data with an interpretation of regional faulting. Special thanks go to Richard R. Thorup for sharing his extensive knowledge of the geology of the quadrangle. Heather V. Goss (USGS and Environmental Careers Organization) added a structure layer, including strikes and dips and fold axes, to the digital map file, annotated and formatted the map to conform to USGS publication standards, and made corrections to the map after technical reviews. She wrote the metadata for the digital file, formatted the text to conform to USGS publication standards, and changed and added information after technical review.

Logical_Consistency_Report: Polygon and chain-node topology present Completeness_Report: The report is intended to describe completely the bedrock geology at 1:24,000 scale. Geologic information only mappable at larger scale has been omitted. In addition, landslide deposits are for the most part not recorded. Further, Quaternary surficial deposits in many areas have been intentionally undifferentiated. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Well located data items are intended to have a horizontal positional accuracy within .62 mm at 1:24,000 scale, or within 15 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. See Aitken (1997) for information regarding the horizontal positional accuracy of the basemaps. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: No vertical positional data recorded. See Aitken (1997) for information regarding the vertical positional accuracy of the basemaps used to create the plotfiles of the geologic maps.

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, although in some cases these items are not used. 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 only recorded in the table SK-STRC.PAT Entity_and_Attribute_Detail_Citation: This report, skmf.txt, skmf.pdf, or skmf.ps Distribution_Information: Metadata_Reference_Information: Metadata_Date: 20010118 Metadata_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: R.W.
