Chrysotile-astestos deposits of Arizona (Supplement to Information Circular 7706).
Tucson, AZ: U.S. Department of the Interior, Bureau of Mines, IC 7745, 1956 May; :1-41
This paper is one of a series covering the mineral resources of the Nation. It supplements Bureau of Mines Information Circular 7706, Chrysotile-Asbestos Deposits of Arizona, by the same author. The 18 additional properties that were examined after release of the former circular are described in this report, virtually completing the list of known asbestos properties in Arizona. The general location map (fig. 1) shows the statewide distribution and indicates the concentration of deposits around Globe. With few exceptions the properties described are on unsurveyed land, but the stated approximate locations have been determined by appropriate projections. The township and range numbers refer to the Gila and Salt River base and meridian. All the deposits discussed are on unpatented mining claims. The history of production of asbestos in Arizona, origin, varieties, mode of occurrence, uses, and mining methods are covered in some detailing the earlier publication.
