Reconnaissance Geology and Structure of the Coso Range, California.
Abstract
The Coso Range was mapped at a scale of 1:62,500 in order to collect basic petrographic, petrologic, and chemical data. Special attention was given to individual fault zones and regional fault patterns. The basement in the Coso Range consists of Mesozoic age granitic rock and metamorphic inclusions. Tertiary aged dacite tephra and flows cover the northern and western parts of the Range. Quaternary basalts, andesites, and rhyolites cover the central and eastern parts of the Range. The Coso Range has been broken by Basin and Range extensional faulting, as seen in extensive horst and graben development and right-slip displacement evidenced by ramping, oblique-slip striations, and lateral-slip fault morphology.
