摘要
Los Quilos copper deposit in Chile is located in alkaline andesite and andesitic welding breccia of Lower Cretaceous Los Quilos rock unit. Ore bodies are in vein, vein like bodies and lenses controlled by strike slip shear faults trending NW, SN, and NE, respectively. Minerals occur in zones at ore body. Bornite-chalcocite-hematite is the inner zone and outward and to depth is chalcopyrite-pyrite zone. Regional alteration is common, such as hematitization, propylitizatition, albitization etc. The Cu-mineralization-related alterations are silicification, carbonation, chloritizatioon, hematitization, sodium and potassium alterations. Mesozoic volcanic-sedimentary rock sequence, high permeability zone and malachitization are the prospecting marks.
