ABS
The formation of Arizona minerals through geologic time can be understood in the context of the plate tectonic setting of the southwestern United States. Numerous orogenic (mountain building) episodes generated mineralization when Arizona was on the leading edge of a continent. Arizona was subjected to volcanism and plutonism that rose from the plate that was being subducted under the westward-advancing North American continent. The ages of mineralization in Arizona range from Proterozoic (Late Precambrian – 2000 Ma [million years ago]) to Tertiary (2 Ma). Deposition of minerals is associated with five orogenies (mountain building episodes) in the Proterozoic and five orogenies in the Mesozoic and Cenozoic. Three orogenies in the Paleozoic that affected the eastern United States influenced the deposition of sedimentary rocks in Arizona. The thirteen orogenies that affected deposition of collectible minerals and productive mining districts in Arizona are listed in Table 1.
Key words
