Abstract
A 1|24,000-scale, full-color geologic map of the Nelson SW 7.5' Quadrangle in Clark County, Nevada, with two cross sections and 42 geologic units. The quadrangle includes parts of the Highland Range, Eldorado Valley, and Piute Valley. It contains excellent exposures of early to middle Miocene volcanic and sedimentary rocks, the upper part of the approximately 16.6 Ma Searchlight pluton, and the northernmost part of the Searchlight mining district. The Miocene section rests nonconformably on Early Proterozoic gneiss. As a result of middle Miocene extension, Tertiary strata are moderately to steeply tilted and cut by complex arrays of normal faults. Flat-lying Quaternary alluvial-fan deposits dominate Eldorado and Piute Valleys and onlap tilted Miocene strata in the Highland Range.
