Ore Deposits Formed by Oxidation and Supergene Enrichment When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to .
Abstract Many diverse ore systems are classified together as iron oxide copper-gold (lOCG) deposits based on an empirical definition arising primarily from geochemical features that do not specify tectonic setting, geologic environment, or sources of ore-forming fluid, metals, or other ore components
