Mineral resource potential map of the Benton Range Roadless Area, Mono County, California Mineral resource potential map of the Benton Range Roadless Area, Mono County, California
Tungsten-bearing rocks in the Benton Range Roadless Area occur in tactite lenses within the Paleozoic metasedimentary units that surround and are intruded by Triassic granodiorite of the Benton Range. High anomalous tungsten values were found in the southern part of the study area. Quartz-vein deposits with copper, lead, zinc, and silver may occur within the Jurassic granitic rock in the
