Zeigler New Mexico Bureau of Geology and Mineral Resources Open-file Map Series Zeigler Geologic Consulting, Albuquerque, NM, 87123 OFGM 192 COMMENTS TO MAP USERS Mapping of this quadrangle was funded by a matching-funds grant from the STATEMAP program of the National Cooperative Geologic Mapping Act, administered by the U. S. Geological Survey, and by the New Mexico Bureau of Geology and Mineral Resources, (L. Greer Price, Director and State Geologist, Dr. J. Michael Timmons, Geologic Mapping Program Manager). A geologic map displays information on the distribution, nature, orientation, and age relationships of rock and deposits and the occurrence of structural features. Geologic and fault contacts are irregular surfaces that form boundaries between different types or ages of units. Data depicted on this geologic quadrangle map may be based on any of the following: reconnaissance field geologic mapping, compilation of published and unpublished work, and photogeologic interpretation.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 geologist(s). Any enlargement of this map could cause misunderstanding in the detail of mapping and may result in erroneous interpretations. Site-specific conditions should be verified by detailed surface mapping or subsurface exploration. Topographic and cultural changes associated with recent development may not be shown. New Mexico Bureau of Geology and Mineral Resources New Mexico Tech 801 Leroy Place Socorro, New Mexico 87801-4796 Cross sections are constructed based upon the interpretations of the author made from geologic mapping, and available geophysical, 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 contents of the report and map should not be considered final and complete until reviewed and published by the New Mexico Bureau of Geology and Mineral Resources.

I thank Dr. J. Michael Timmons for logistical support and Stacy Timmons for contact information for local land owners. Land owners who graciously granted permission for this project include: Benton (for McCasland Ranch), Coupland, Melton, Hibbard, Mr. Rand French (Marbob Oil, Artesia, NM), Kinkaid (for Cauhape Ranch), Datola, Evrage, Rodarte, Kniepcamp, Rice and Mott. A very special thanks goes to Jay and Kristy Powell for allowing me to stay with them for the duration of this project. Dr. Barry Kues identified invertebrate fossil material from the San Andres Formation.
