A study of the ore-prospecting work based on multiple geosciences information in the Jinchuan Cu-Ni deposit

The Jinchuan Cu-Ni deposit is one of the world-famous typical superlarge copper-nickel deposits.Based on the feasibility test of the integrated ore-prospecting work based on multiple geosciences information on the known profile,in combination with geological characteristics of the ore deposit,the authors determined geological,geochemical and geophysical ore-prospecting criteria and established a geological-geophysical-geochemical model for ore-prospecting work in the depth and the lateral areas of the Jinchuan Cu-Ni deposit.Based on this model,the authors carried out ore prognostic work in the depth and the lateral areas of the II ore district within the Jinchuan Cu-Ni deposit and found five target areas with ore-prospecting potential.In the No.2 multiple information integrated anomaly zone of Type I target area,drilling verification revealed a concealed Cu-Ni ore body.
