Index of Arizona geologic maps published for 1925-2015

The Arizona Geological Survey just released a geologic map index by staff geologists Jon Spencer and Steve Richard comprising maps that are available from the AZGS’ online Document Repository. The index includes the citation, location and map scale data for approximately 720 maps of areas within Arizona derived from approximately 500 publications published by AZGS. The Geologic Map of Arizona (2000) is used as background to the map indexes, identifying regional maps with scale ranging from 1:100,000 to 1:1,000,000. Additional figures identify detailed geologic maps with scale ranging from 1:200 to 1:99,000. Each map is labeled with a publication serial number, for example “OFR 95-1” or DGM-76. [Right, index map of 1:24,000 quadrangle maps]

The map indexes are followed by a list of map citations organized alphabetically by publication serial number (pubNum). Generally, a user of this index would locate an area of interest on a map index, identify the publication numbers for maps in the area of interest, and then find the relevant citation or citations. With the citations one can then retrieve the desired maps from the document repository at the Arizona Geological Survey web site.

  1. They appear to have forgotten the Petrified Forest NP map ;)

  2. Bill, the team assures me that Petrified Forest map CM-12-A is outlined in Figure 8, page 9, just as it should be. Let us know if you have trouble spotting it.
