Geologic setting

Geologic description

The El Paso prospect is in the Coast Range plutonic-metamorphic complex which consists of high-grade schist and gneiss intruded by Cretaceous and Tertiary granodiorite (Brew and Ford, 1984). Brew and Ford (1974) indicate that rocks at the prospect are shallow, tonalitic to granitic plutons that intrude and contact metamorphose high-grade, regionally metamorphosed, rocks derived from volcanic, pelitic and minor carbonate strata of unknown protolith age. Roof pendants of the metamorphic rocks are common, as are mafic and aplite dikes (Miller and others, 1997).
Wells, and others, 1986, report this as a Ni-Cu prospect. No other information is available. Claims were active from 1970 to 1976 (Wells and others, 1986).
