David J. McCraw, Adam S. Read, John R. Lawrence, Fraser Goff, and Cathy J. Goff New Mexico Bureau of Geology & Mineral Resources/New Mexico Tech Socorro, NM 87801 (575) 835-5420 http://geoinfo.nmt.edu 2009 https://geoinfo.nmt.edu/publications/maps/geologic/ofgm/details.cfml?Volume=194 The GIS project and map products included in this open-file report reflect a compilation and interpretation of geologic data for the San Mateo 7.5-minute quadrangle, located on the northwest flank of Mount Taylor, within the Grants Uranium Belt. The data were compiled by D. J. McCraw, as part of the NMBGMR STATEMAP program. This map is being released as an open-file geologic map because of renewed interest in this area. Funding for this geologic map was provided by both the National Cooperative Geologic Mapping Program (NCGMP), administered by the U.S. Geological Survey, and by the New Mexico Bureau of Geology and Mineral Resources. Data depicted on this geologic map are based on field geologic mapping, compilation of published and unpublished work, and photogeologic interpretation. The quadrangle was previously mapped by E. S. Santos and published by the U.S. Geological Survey as Map GQ-517 in 1966. Mapping responibilities for this current version were: McCraw: Pliocene-Quaternary sediments; Read: Cretaceous sedimentary rocks; and Lawrence, Goff, and Goff: Pliocene volcanic rocks. As with all NMBGMR STATEMAP geologic quadrangle maps, locations of contacts are not surveyed, but are interpretively plotted onto a topographic base map; therefore, the accuracy of contact locations depends on the scale of mapping and the interpretation of the geologists involved. Geologic cross sections are constructed based upon the interpretations of the authors made from geologic mapping, available geophysical (regional gravity and aeromagnetic surveys), and subsurface (drillhole) data. Cross sections should be used as an aid to understanding the general geologic framework of the map area, and not be the sole source of information for use in locating or designing wells, buildings, roads, or other man-made structures. The views and conclusions contained in this document are those of the authors and should not be interpreted as necessarily representing the official policies, either expressed or implied, of the State of New Mexico, or the U.S. Government. -------------------------------------------------------------------------------- DOWNLOADS: The downloads are organized as follows: - A stand-alone 36in x 50in full-color map (containing map symbols, map unit descriptions, map unit correlation chart, and cross sections), as well as the accompanying report are available as pdf files (OFGM-194_San _Mateo.pdf and OFGM-194_San_Mateo_Report.pdf). - GIS data of the map only are available in OFGM-194_San_Mateo_geology.zip. These data were produced in ArcMAP v. 9.3.1. The zipped folder contains the map file geodatabase (San_Mateo.gdb), the map file (San_Mateo_v_9_3.mxd), and base map files. The geodatabase is structured using the NMBGMR Geologic Data Model, v. 1.0.2: https://geoinfo.nmt.edu/statemap/datamodel/home.html -------------------------------------------------------------------------------- SYSTEM REQUIREMENTS: A computer capable of running some or all of the following software: Adobe Acrobat (v.6 or later) to view the Plates (*.pdf) -- freeware: http://get.adobe.com/reader ArcGIS (v. 9.3.1 or later) to open GIS project/data (*.mxd) -------------------------------------------------------------------------------- METADATA: Detailed metadata is included with the GIS data regarding feature classes and tables. -------------------------------------------------------------------------------- SUGGESTED CITATION: McCraw, D.
