摘　　要：根据异常元素共生组合特点、含量变化、地质化学信息、成矿地质背景,同时参考其他信息资料进行评价排序。对内蒙古自治区呼伦贝尔市诺敏大山等三幅1∶5万地球化学单元素异常和综合异常进行评序,并经过了异常查证,排序靠前的元素是Au、As、Mo、Bi、Pb、Sb、Cd、Ni等,这些元素均与热液活动密切,是区内的主要成矿元素。其评序结果客观准确,对下一步寻找金钼铅多金属矿产具有指导意义。Binding geochemical information and regional metallogeny is a method to assess and analyze the multi-element anomaly of regional geochemical exploration for metallogenie prognosis.Evaluation and ranking of 1 ： 50000 soil geochemical anomaly of numindashan sheet,etc in Hulunber, Inner Mongolia was discussed in this paper. The result showed that elements Au, As, Mo, Bi, Pb, Sb, Cd, Ni are at the top, which are closely associated with mineralization, and it is the main metallogenie elements in this area. The evaluation results are proved to be objective and accurate, and it is of guiding significance for the next stage of Au-Mo-Pb polymetallic ore prospecting.
