It was produced from either scans of hand-drafted originals or from digitally drafted original maps and figures using a wide variety of software, and is currently in cartographic production. COMMENTS TO MAP USERS It is being distributed in this draft form as part of the bureau's Open-file map series Mapping of this quadrangle was funded by a matching-funds grant from the STATEMAP program (OFGM), due to high demand for current geologic map data in these areas where of the National Cooperative Geologic Mapping Act, administered by the U. S. Geological Survey, A geologic map displays information on the distribution, nature, orientation, and age relationships STATEMAP quadrangles are located, and it is the bureau's policy to disseminate and by the New Mexico Bureau of Geology and Mineral Resources, (Dr. Peter A. Scholle, of rock and deposits and the occurrence of structural features. Geologic and fault contacts are Director and State Geologist, Dr. J.

Data depicted on this geologic quadrangle map may be based on any of the following: reconnaissance field After this map has undergone scientific peer review, editing, and final cartographic geologic mapping, compilation of published and unpublished work, and photogeologic interpretation. production adhering to bureau map standards, it will be released in our Geologic Map Locations of contacts are not surveyed, but are plotted by interpretation of the position of a given (GM) series. This final version will receive a new GM number and will supercede contact onto a topographic base map; therefore, the accuracy of contact locations depends on the this preliminary open-file geologic map.
