摘要: 提要：金川铜镍矿床是世界级典型的超大型硫化铜-镍矿床之一。根据在已知剖面上开展的多元地学信息综合找矿可行性试验结果，结合该矿床的地质特征，确立了地质、地球化学、地球物理找矿标志，并建立了金川铜镍矿区深边部地-物-化综合找矿模式。依据上述找矿模式, 在金川Ⅱ矿区深边部开展找矿预测工作, 发现了5个具有找矿前景靶区，其中在Ⅰ类靶区②号多元信息综合异常带深部经工程验证发现了隐伏铜镍矿体。Abstract: Abstract：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.
