Significant differences between the lead-zinc-silver and copper ore bodies. Unlike the lead-zinc-silver deposits, the copper orebodies appear epigenetic. Two texturally distinct generations of iron sulfides. Later (relative to the lead-zinc mineralization) origin of the main copper ore bodies from the basement metamorphic and granitic complexes. Direct relationship between the regional metamorphism, generation of hypersaline fluids, and metal extraction.--Modified journal abstract.
