Abstract
The ultramafic mass consists mainly of serpentinized dunites and harzburgites, with minor amounts of pyroxenites. Chromite pods are locally abundant. Minor amounts of talc rock, tremolite schist, carbonate rock, and quartz veins are found concentrated along shears and fractures in the ultramafic assemblage. Contact alteration or metamorphism of the host rock surrounding the ultramafic bodies has not occurred, and the mass appears to have undergone serpentinization prior to emplacement. The Melones ultramafic complex is similar in structure, rock type, and mineralogy to Alpine complexes found throughout the west coast of the United States and Canada. It probably represents mantle material that was tectonically emplaced in the cold state during the early phase of the orogenic cycle.
