Updates and revisions are anticipated, so please refer to web site. The GIS projects and map products included in this open file report are for a compilation and interpretation of geologic data. ----------------------------------------------------------------------- More than half of the detailed geologic mapping work this compilation is based on geologic quadrangle mapping performed by the New Mexico Bureau of Geology and Mineral Resources under the STATEMAP component of the USGS National Cooperative Geologic Mapping Program. The U.S. Geological Survey and the New Mexico Bureau of Geology and Mineral Resources (a division of the New Mexico Institute of Mining and Technology) provided funding for geological mapping. Data depicted on this geologic map are based on field geologic mapping, compilation of published and unpublished work, and photogeologic interpretation. Locations of contacts are not surveyed, but are plotted by interpretation of the position of a given contact onto a topographic base map; therefore, the accuracy of contact locations depends on the scale of mapping and the interpretation of the geologists involved. Original geologic mapping was conducted as scales of 1:12,000, 1:24,000, and 1:50,000, so some variation in detail should be expected on this compilation. Geologic cross sections are constructed based on the interpretations of the author made from geologic mapping, available geophysical (regional gravity and aeromagnetic surveys released by U.S. Geological Survey), and available subsurface (drillhole) data. The geologic cross sections are intended as an aid to understanding the general geologic framework of the map area, and should not be the sole source of information for use in locating or designing wells, buildings, roads, or any other man-made structures. The views and conclusions contained in this document are those of the author 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.

Version 10.0 is preferred. or ArcReader (V 9.1 or later) to view GIS projects/data (*.pmf) -- freeware: Geologic unit ID labels require Stravetica true type font (USGS) to display properly. ARC Map layer files are included if Arc Map project files do not load properly. Shapefiles for most of the Geodatabases are included in the GISData\Shapefiles\ subdirectory. An ARc GIS version 8.2 project file with only the Geologic Map layout is included in the Shapefile directory.
