Granite intrusions 190million years ago enriched many veins with minerals and generated copper porphyry gold deposits. The breakup of Pangaea was accompanied by the subduction of the Farallon Plate, which drove volcanism during the Nevadan orogeny and the Sevier orogeny in the Mesozoic, which covered much of Arizona in volcanic debris and sediments.

During this period in the Proterozoic, the Yavapai, Pinal and Vishnu schist rocks formed due to intense metamorphism and were intruded with granites. Native Americans were drawn to the mountains in part because summer temperatures are typically eight to 12 degrees cooler at the highest elevations than on the desert floor. Volcanic material is interbedded with dune sandstones in the Santa Rita Mountains, to the south of Tucson and correlate with the Aztec Sandstone and Navaja Sandstone, spanning northern Arizona to Zion National Park. The high point is 2959 feet. Although the region was tectonically quiet and had no volcanic activity or igneous intrusions, it was impacted by a series of major orogenies to the east. Extensive erosion of these mountains shed sediments westward into a shallow sea in Arizona. These, in turn, are overlain by sandstone, siltstone and shale deposited under near-shore conditions, which were covered over 515 to 488million years ago by limestone, traced with worm boreholes, as well as thin beds of conglomerate. At the time the modern-day Arizona Rangers were formed, all living members of Arizona Territorial Rangers were designated members for life of the modern-day Arizona Rangers. It's located in Arizona, United States. These erosive processes are ongoing, and the topography of the Appalachian Mountains continue to change. The lava flows, volcaniclastic, and epicIastic rocks can be separated into two age groups: the first of Oligocene and Miocene age and the second of late Miocene-Pleistocene age.
