Geologic Map of New Mexico, scale 1:500,000, New Mexico Bureau of Geology and Mineral Resources, 2003, 2 oversized sheets, 54" x 47" and 50" x 42," ISBN: 1-883905-16-8 Projection: Datum: NAD 1927 Lambert Conformal Conic central meridian: -106° standard parallels: 33° and 45° reference latitude: 0° linear unit: meter This map represents the first substantial revision of the geologic map of New Mexico at this scale since the appearance of the State Geologic Map of New Mexico by Carle H. Dane and George O. Bachman, published in two sheets by the U.S. Geological Survey (in cooperation with the New Mexico Bureau of Mines and Mineral Resources) in 1965. The present compilation was started in 1985 by G. Robert Osburn, under the directorship of Frank Kottlowski. The bulk of the compilation was accomplished between 1987 and 1998 by Orin J. Anderson and Glen E. Jones. Since 1998 the map has been reviewed and revised by many other workers (listed below). The present map reflects substantial revisions to the Anderson and Jones compilation. Earlier versions of that compilation appeared in 1994 as Open-file Report # 408 of the New Mexico Bureau of Mines and Mineral Resources, and in 1997 as Open-file Report 97-52 of the U.S. Geological Survey. Work on this project has spanned the administrations of three directors at the New Mexico Bureau of Geology and Mineral Resources: Frank Kottlowski, Charles Chapin, and Peter Scholle. This map was created in Macromedia Freehand from ArcInfo files created by Greg Green, U.S. Geological Survey.
