摘　　要：赞比亚矿产资源非常丰富,但以往只把铜钴矿及宝石矿作为重点找矿目标,对金矿等勘查重视程度不够。在赞比亚西北省兴安矿区开展了1∶1万土壤地球化学测量工作,通过元素分布特征、单元素异常特征、元素相关性分析、相关元素累乘组合异常研究,确定了找矿靶区;经过钻孔深部验证,发现铜金矿体,验证了异常为矿致异常。Zambia possesses very rich mineral resources; nevertheless, in the past work, prospecting focused only on copper, cobalt and gemstone deposits, whereas the attention to gold deposits was very insufficient. Based on 1∶10 000 soil geochemical survey, the authors conducted detailed soil geochemical survey in the Shiganda ore district in Northwest Province of Zambia. Through studying element distribution characteristics, individual element anomaly features, element correlation, and multiplicative combinational anomalies of related elements, the authors determined Au and Cu as the target ore species elements in the study area, and delineated the nextstep prospecting target area.
