Geology

Alteration processes:

Wall-rock alteration within a few inches of the veins is intense, but seldom extends more than 10 to 12 inches beyond the quartz filling. Sericitization and carbonate alteration predominate, but there is some pyritization and in the outer parts of the alteration zone chloritization is present (Ray, 1954). Aplite dike shows evidence of hydrothermal alteration. Oxidation of Fe and Cu minerals.
