Preliminary report on the mineral resource potential of the Red Rocks Escarpment Instant Study area, Clark County, Nevada

The Red Rocks Escarpment Instant Study area in Clark County, Nevada, is 2 mi (32 km) west of Las Vegas and covers about 31,000 acres (12,500 ha) of the rugged Sandstone Bluffs area in the Spring Mountains (fig. 1). It includes the crest of the range, which is slightly higher than 7,200 ft (2,190 m), the Sandstone Bluffs east of the crest where steep cliffs as high as 2,500 ft (760 m) occur, and part of the gently sloping western range front. The Instant Study area (fig. 2) is within land administered by the U.S. Bureau of Land Management.

Lithium in sediments and rocks in Nevada

Reconnaissance geochemical sampling has been conducted by the Lithium Resource Program of the United States Geological Survey for much of the Western U.S. Sediment, rock, and brine samples have been collected in many states, but this report describes just those solid samples collected in Nevada. Further reports by other members of the Lithium Program will describe water samples from Nevada and samples from other states. The purpose of the sampling program was to determine if areas of anonalous lithium could be recognized by reconnaissance surface sampling. The results, however, have been indeterminate because most large lithium deposits occur at depth and appear to be formed when deeply buried. Many may not manifest themselves at the surface at all . Nonetheless, the data derived during the surface sampling program will be presented in this report.
