Analytical results and sample locality map of stream-sediment, heavy-mineral-concentrate, rock, and water samples from the Skedaddle (CA-020-612) and Dry Valley Rim (CA-020-615) Wilderness Study Areas,

Proterozoic amphibolite that crops out in the Lost Basin Range, Mohave County, Arizona is derived from both sedimentary and igneous protoliths. Those amphibolites derived from igneous protoliths are characterized by high Ni and Cr contents, high MgO contents, low Si02 contents and the presence of palladium and platinum. Compositions, textures and stratigraphic considerations suggest that the protoliths varied from ultramafic komatiite to basaltic komatiite to tholeiite. If these represent the actual protoliths, then this Precambrian terrane could be of interest in terms of Cu-Ni sulf ide mineralization associated with komatiites.
