Description
The mineral districts of Arizona delineated in this report are based on the Database for Mineral Districts in the State of Arizona (Richard, 2002) which was in turn based on Metallic Mineral Districts of Arizona (Keith et al., 1983). The newly updated mineral districts data files maintain the previously defined areas that contain mineralization, along with all the original associated metadata. This includes the district classification scheme devised by Keith et al. (1983) for the purpose of outlining areas with mines and linked activity connected to local mineralization and alteration with consistent geologic characteristics. The utility in doing so originally was to provide a sense for the broad characteristics of the types of deposits found in individual districts where only one category was fit to each district. New mineral districts were not added to the database. Instead, this report appends the original data with an additional classification scheme based on the United States Geological Survey (USGS) mineral deposit models with origins from open-file reports by Erickson (1982) and Ludington (1985), but officially compiled in Cox and Singer (1986). Additions since then have been released through the USGS to increase the number of deposit types with appropriate models (e.g., Orris, 1998; many others). Mineral deposits discussed in their reports contain descriptive geologic characteristics for a large range of specific mineral deposits and their regional geologic environments. The goal of developing the models was to help assess domestic mineral resources by giving geologists the ability to compare their observations with collective knowledge and experience from a diverse group of geologists (Cox et al., 1986). These classifications also served as the basis for geoenvironmental mineral deposits that describe the fundamental control of mineral deposits on their environment prior to mining activity and the subsequent conditions that occur after mining has commenced (du Bray, 1995). Progress was more recently made and reported on in Seal and Foley (2002). The update to Arizona’s mineral district database therefore serves two purposes: 1) to assist with future mineral exploration and resource assessment and 2) to provide a framework for assessing the environmental impacts mineral districts might have on their local environments.
