StructureGolconda thrust, Pickhandle Gulch thrust, and thrust-related Lower Candelaria shear. Area rocks have been subjected to a successive sequence of recurrent faulting. folding and faulting, with resultant deformationin the Walker Lane structural zone., Pickhandle Gulch Thrust; Candelaria Shear, Alpha, Beta, Bigfoot, East Diablo, County Line and Eastern faults all cut rocks in the mine area. Areas of greatest structural discontinuity coincide with most intense rock alteration and the greatest number of veins.
Tectonic settingback-arc extensional cratonic basin
AlterationSome rocks are sericitized, carbonatized, argillized and silicified due to hydrothermal action pre-dating or accompanying ore deposition.
