摘　　要：江山金矿是皖东浅覆盖区内的典型隐伏矿床,常规化探采集的表层土壤样品异常不明显。利用浅钻在江山金矿区内采集了运积物覆盖层之下的岩石样品。江山金矿岩石地球化学异常明显,根据江山金矿的地球化学特征总结了异常模式。在研究区内共圈定了5处异常区。其中Ⅲ号组合异常为江山金矿的矿致异常。江山金矿外围的组合异常具有寻找Au、Pb多金属矿的良好前景。可在Ⅱ号组合异常内开展进一步的矿产勘查工作,争取找矿突破。The Jiangshan gold deposit is a typical concealed deposit in the shallow overburden area of eastern Anhui.The anomaly of surface soil samples collected by conventional geochemical exploration is not obvious.The rock samples under the overburden of drift load were collected by shallow drilling in the Jiangshan gold deposit area.The rock geochemical anomaly of the Jiangshan gold deposit is obvious,and the anomaly model is summarized based on the geochemical characteristics of the deposit.A total of 5 anomalous areas were delineated in the study area.The composite anomaly Ⅲ is mineralization-related anomaly of the deposit.The composite anomaly in the periphery of the deposit has a good prospect to search for Au and Pb polymetallic deposits.Further mineral exploration work can be carried out in the composite anomaly Ⅱ striving for a breakthrough in ore prospecting.
