dc.descriptionThe Big Sandy Valley is located in Mohave County, northwestern Arizona, and lies between the Hualapai Mountains to the west and the Aquarius Mountains to the east. In Fall 2020, the Arizona Geological Survey began a multi-year geologic mapping campaign starting with the Gunsight Canyon, Aubrey Peak, Tule Wash, Wikieup, and northern half of the Greenwood Peak 7.5’ quadrangles. Mapping continued in 2021-2022 with the Pilgrim Wash, Bottleneck Wash, and Dean Peak quadrangles, the southern half of the Tom Brown Canyon quadrangle, and the eastern half of the Hibernia Peak quadrangle. The Aquarius and Hualapai Mountains are underlain by Paleoproterozoic gneiss intruded by Paleoproterozoic and Mesoproterozoic plutonic rocks. In the Hualapai Mountains, these rocks have been intruded locally by late Cretaceous plutons and several spatially extensive dike swarms. Two plutons in the southern Hualapai Mountains, and at least some of the dikes, are associated with weakly developed hydrothermal alteration and mineralization inferred as being related to a porphyry copper system. On both sides of Big Sandy Valley, the plutonic and metamorphic basement rocks are overlain unconformably by two successions of predominantly sedimentary basin-fill deposits. The lower succession, the Tule Wash formation (informally defined in the Tule Wash quadrangle), together with its basement has been dissected and tilted by Basin-and-Range normal faults. This succession and the older rocks are overlain unconformably by the Big Sandy Formation, which is generally undeformed. River, tributary, and fan deposits record the history of basin filling and subsequent dissection due to integration into the larger Bill Williams River watershed.en_US
