Rocks of the Goshute-Toano Range, Elko County, Nevada, between White Horse Pass on the south and Silver Zone Pass on the north, record a complex Mesozoic and Tertiary history of metamorphism, contractional and extensional deformation, and igneous activity. Paleozoic strata comprise seven distinctive structural tracts, separated from each other by low-or high-angle faults. These tracts are grouped here into three structural-thermal levels separated by low-angle faults: (1) a lower level of Cambrian to Mississippian sedimentary rocks that were strongly folded and metamorphosed in Mesozoic time, (2) a middle level of Cambrian to Mississippian, nonmetamorphosed sedimentary strata that were heated moderately, weakly folded, thinned by bedding-parallel faults, and segmented by high-angle faults, and (3) an upper level of Pennsylvanian, Permian, and younger rocks that were heated only slightly and, over large areas, were broken up, tilted, and dispersed by normal faulting in Miocene time.
