These sedimentary, metasedimentary, and metavolcanic rocks were deposited, deformed, and intruded contemporaneously with the Paleoproterozoic schists of the Vishnu Basement Rocks found in the Grand Canyon. The rocks intruded by the Mint Wash Granodiorite are also part of the same tectonostratigraphic terrane, Yavapai tectonic province. The rocks that are part of the Yavapai tectonic province and intruded by the Mint Wash Pluton formed in volcanic island arcs overlying one or more subduction systems, similar to modern volcanic arcs in the Aleutian Islands, the Philippines, and Indonesia. Then, granitic igneous rock, e.g. the Mint Wash Pluton, were later intruded into them when these volcanic arcs collided with and welded to Laurentia and each other ca. 1.7- 1.66 Ga during the Yavapai and Mazatzal orogenies.
