摘　　要：握玛沟铜多金属矿位于东昆仑"铜峪沟铜矿田"内,区内有较好的成矿地质背景。利用1∶1万土壤地球化学测量数据,对Pb、Zn、Cu、Au、As元素进行了相关性分析及聚类分析,分析结果显示了中、低温不同的成矿期次,并建立了以Pb-Zn-Cu为异常组合、Au-As为异常组合的找矿标志。在圈定的3处综合异常内共圈出铜矿化体10条,金矿化体2条,表明了1∶1万土壤地球化学测量成果可以作为热液充填型矿床找矿的有效依据。Womagou Cu-polymetallic Mine is a part of the Tongyugou copper mine field,located in eastern Kunlun,in which the geological settings provide essential requirements for mineralization. In this study,the geochemistry data with the scale of 1∶ 10 000 of this area has been used for correlation and clustering analysis of 5 metallic elements（ Pb, Zn, Cu, Au and As）. It is revealed that this area has experienced a variety of mineralization stages as the temperature ranges from medium to low level. Furthermore,an ore-prospecting criteria has been proposed with the anomaly combination of Pb-Zn-Cu,and Au-As. With this criteria,10 copper mines and 2 gold mines have been successfully detected. It is proved that the geochemistry data with the scale of 1∶ 10 000 can be used for ore-prospecting with the type of hydrothermal fluid filling deposit.
