Description:

Abstract:

This Open-File report is a digital geologic map database stored in a computer in the U. S. Geological Survey offices in Menlo Park, California. The study area includes the Monterey Peninsula and part of the Carmel Valley area. Geologically, this region is situated within the complexly deformed Salinian block between the active San Andreas fault to the northeast and the San Gregorio fault zone to the southwest. It also is characterized by compressional tectonics related to the San Andreas fault system and includes many poorly understood subsidiary faults (Greene and others, 1988). A series of high-angle faults trends northwestward across the quadrangles. Most of the faults in the area are discontinuous, with some less than 1 km long; however, the Tularcitos fault zone continues across the entire mapped area. These faults displace the Monterey Formation and locally offset Quaternary deposits.

Purpose:

To provide to the public a digital geologic map database of the Monterey and Seaside 7.5' quadrangles.

Data_Set_Credit:

The present study was initiated as part of a regional study of the earthquake hazards of the San Francisco Bay region and is part of the National Earthquake Hazards Reduction Program (NEHRP) of the U.S. Geological Survey. Earl E. Brabb (USGS) established this project, provided base maps, aerial photographs, and other materials, and helped to obtain funding for much of the field work. Partial funding was provided by USGS NEHRP award number 1434-94-G-2443 to Rosenberg and Clark. Supplemental funding was provided by the Monterey County Planning Department under the supervision of Catherine S. West. We are also grateful to the USGS Volunteer Scientist Program for sponsoring Clark and Rosenberg.
Many people gave freely of their time and resources. John C. Tinsley (USGS) and Earl E. Brabb helped by visiting the study area and sharing their opinions. H. Gary Greene (Moss Landing Marine Laboratories), Joseph W. Oliver (Monterey Peninsula Water Management District), Oliver E. Bowen (consulting geologist), and John Logan (consulting geologist) provided unpublished data from their files. Kristin McDougall (USGS) identified and interpreted Miocene foraminifers. Michael P. Bohan (IUP) digitized the geologic contacts, and Carl M. Wentworth (USGS) and Russell W. Graymer (USGS) assisted with developing the digital map. The Explanation of Units sheet was created by Zenon C. Valin (USGS) with assistance from Karen Wheeler (USGS). Carolyn Randolph prepared this booklet announcing the release of the database in Open Files. Special thanks go to Thomas W. Dibblee, Jr., who participated with Clark in the earlier field mapping and shared his unique perspective of the regional geology, and to Richard R. Thorup for sharing his extensive knowledge of the local geology.

Native_Data_Set_Environment: 7.0.3

Data_Quality_Information:

Logical_Consistency_Report:

This digital map database updates a previously published map (Clark and others, 1974) and other published and unpublished data (see Sources of Data in mo-se.ps2) with substantial new mapping by the authors. Together with the accompanying text file (mo-se_geo.txt or mo-se_geo.ps), it provides current information on the stratigraphy and structural geology of the area.

Completeness_Report:

This map is intended to be of general use to engineers and land-use planners; however, its small scale 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, 1992).

Process_Step:

Process_Description:

The geologic map information was digitized from stable originals of the geologic maps 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 place 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 1:24,000 were removed.
Base map layers were prepared from scale-stable printing positives of the U.S. Geological Survey Monterey (1968 edition) and Seaside (1968 edition) 1:24,000 topographic maps, which have a 20-foot contour interval. Scanned images were transformed from scanner coordinates to projection coordinates with digital tics placed by hand at quadrangle corners. The images were trimmed interactively by hand using ALACARTE to conform to the area of the geologic coverages. Small mismatches at the boundaries caused by slight differences in the original maps remain in the two base map coverages. These base map layers are digital images but no information other than location is attached to the pixels.
