CARSON-ICEBERG ROADLESS AREAS, CALIFORNIA.

Areas of probable mineral-resource potential for base and precious metals, molybdenum, tungsten, and uranium were identified in the Carson-Iceberg Roadless Areas, California. During the mineral-resource study existing geologic mapping was modified and supplemented with new mapping; geophysical studies were conducted in the form of gravity and aeromagnetic surveys; stream-sediment and rock samples were collected in all of the drainage basins and chemically analyzed; and studies of mines, prospects, and known mineralized areas were conducted. No evidence of fossil fuel resource potential was found in the study.
