StructureVirgin Fault, a major north-striking fault. Copper Canyon Fault is another major fault in the district. The Roberts Mountain thrust, Dewitt Thrust, and Golconda Thrust have all telescoped the various formations in the district., N-S trending faults; minor NW- and NE-trending faults. Some faulting is Late Permian in age.
AlterationAlteration types present in host rocks are varying degrees of potassic, pyritic, silicic, propylitic, and sericitic alteration.
