Database for Mineral Districts in the State of Arizona - Based on Metallic Mineral Districts of Arizona

The districts delineated in this report are based on Metallic Mineral Districts of Arizona (Ari-zona Geological Survey Map 18) [Keith et al.,1983a], which served as a starting point for this da-tabase. The mineral districts attempt to identify mineralized areas based on geologic character and age of mineralization. This database is an attempt to assign accurate spatial locations to the dis-tricts shown on the Keith et al. [1983a] map, and to provide more in depth information on the geology of the districts. The districts are classified according to the system elaborated in Keith et al. [1983b], a report which was published in conjunction with the Keith et al. [1983a] map. This report discusses definition of the districts, and has a summary of metal production reported to the U.S. Bureau of Mines, and in published sources available as of 1981 [Keith et al., 1983b]. The production data included in the table DistrictDataAZMIN are imported from a previous Arizona Geological Survey database [Welty et al., 1989] that contained the production data from the printed publication [Keith et al., 1983b]. Minor discrepancies with data reported in Keith et al [1983b] are the result of edits to that data made during final production of the published report and not updated in the database version that has been preserved, or are the result of edits, correc-tions and additions that have been made to this database since publication of the original produc-tion summary.
