摘　　要：乌拉根矿床为近年来发现的大-特大型热卤水成因的层控砂砾岩型铅锌矿床。根据该区区域和矿区地质、地球化学资料,对矿床地球化学异常模式进行了研究。应用数理统计确定了矿床的元素组合、分带特征。通过钻孔原生晕的研究,确定了元素轴向分带系列及前缘元素和近矿元素的比值关系,对预测盲矿、判断矿床的剥蚀程度具有较大意义。初步总结了矿床地球化异常成晕模式,为寻找该类型铅锌矿床提供了地球化学依据。Wulagen ore deposit, discovered recently, is a large - super large, hot - brine SEDEX, stratabound sandstone - con- glomerate - type Pb Zn ore deposit. We study the geochemical abnormal pattern on the bases of geology and geochemical data of regional and mine area and determine the element association, distribution characteristics with mathematical statistics. And we determine ele- ment axial distribution, and the ratio relationship between front elements and elements adjacent to ore bodies on the bases of primary halo of hales, which is meaningful for predicting deep blind ore body and determining erosion depth of ore body. Here we summarize the geochemical halo - forming model of ore deposit and supply geochemical basis for exploring this type Pb Zn deposit.
