The Rockies were formed during the Laramide orogeny, starting around 80 to 50 million years ago and ending roughly 35 million years ago. In southern Arizona, the Proterozoic rocks consist of the satiny, greenish-gray Pinal Schist. Groundwater serves to augment surface water. The Buttes are now protected within Papago Park, jointly Uplift and exhumation were the result of horizontal extension of Earth's crust. Texas Canyon is a massive granite formation that has weathered over the eons to create a jumble of rocks that catch the eye. The Blue Mountains landscape resulted from the erosion of bedrock as it was uplifted during about the last 15 million years. The oldest rocks in Arizona likely date to the late Archean or early Proterozoic, although evidence of earlier geology was overwritten during the Yavapai orogeny and the Mazatzal orogenymajor mountain building events 1.8 to 1.6billion years ago. Today, we know these blocks as Camelback Mountain and the Tempe Buttes. The arid mountains are within the Navajo Indian Reservation.

Arizona's oldest rocks overall are metamorphosed volcanic rocks, including basalt and rhyolite and related sedimentary rocks, that now constitute the bottom of the Grand Canyon and formed beginning 1.8billion years ago. These landforms are most often composed of sedimentary rock, formed by the accumulation and compression of sediment (which may consist of rock fragments, remains of microscopic organisms, and minerals). The Mesoproterozoic formations in the Grand Canyon are overlain by the 850million year old, Neoproterozoic Chuar Group and Sixtymile Formation sedimentary rocks. That is the face of a cork that popped up after the caldera had filled up, Gootee said. Lava flows and granite intrusions built up the Galiuro Mountains and Chiricahua Mountains. How were the mountains of Greece formed? In the last 14million years of the Miocene, Pliocene, Pleistocene and the current Holocene, the subducting Farallon slab was cut off by strike-slip motion on the San Andreas Fault, coupled with a transform boundary.
