Book excerpt: K-Ar dating of alunite from Tyrone, Morenci, Ajo, San Xavier North and Silver Bell, jarosite from San Xavier North and Ajo; and stratigraphic evidence from Cactus-Carlotta, Ray, Santa Cruz, and San Manuel provide evidence that the second post-volcanic stage of supergene mineralization in the region was initiated by the Late Miocene Basin and Range event. This third stage of supergene alteration and mineralization came to an end when establishment of semi-arid climatic conditions increased the rate of erosion and decreased the rate of chemical weathering in the region. Therefore, prior to large scale open pit mining, most of the supergene deposits in the region were, temporarily at least, inactive.

This book was released on 2000 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Post-mineral structural dismemberment of the western and northwestern edge of the Cananea porphyry copper district has controlled, to some degree, the distribution and extent of secondary copper mineralization of deposits in that part of the district. Geologic mapping, detailed analysis of basin fill and pediment gravel sedimentology, and synthesis of existing structural and mineralogical information for the Mariquita deposit in particular was employed to better understand the post-mineral structural history of the northwestern Cananea district. The overall goal is to place some constraints on the relative timing between unroofing and enrichment of the deposits within the district.
