Geology of Nevada
Journal Article: Geology of Nevada
Geology plays a central role in Nevada's human history,economy, and future. Cordilleran tectonics have created the Basinand Range landscape and interior drainage of the Great Basin,provided a rain shadow to make Nevada the nation's driest state, and generated frequent earthquakes along normal and strike-slip faults. Geology is key to reducing risks from Nevada's natural and anthropogenic hazards (earthquakes, flash floods, drought, land subsidence, erosion after wildland fires, landslides, swelling and collapsing soils, radon, arsenic, and others). Nevada's geologic fortunes make it the leading state in the production of gold, silver, barite, lithium, and mercury and a major producer of geothermal power and gypsum. The metals are primarily related to igneous activity, with major pulses of magma during the Jurassic, Cretaceous, and Tertiary. Barite is mined from Paleozoic sedimentary rocks, and gypsum occurs in sedimentary beds of Permian, Triassic, Jurassic, and Tertiary age. Lithium is extracted from brine beneath an unusual playa. Geothermal power production primarily occurs along Quaternary faults. We are in the midst of the biggest gold-mining boom in American history. The Carlin trend is one of the world's premier gold-mining regions, and reserves along the trend and elsewhere in Nevada will sustain the boom for at least two more decades. Nevada's booming population will continue to increase demands for construction raw materials and for geological information to help manage growth while minimizing losses from geological hazards.
