摘　　要：在1:5万土壤测量的基础上,对内蒙古乌尔其汗地区的地球化学特征进行了初步分析。对元素分布特征、单元素异常特征、元素相关性分析、异常元素组合特征进行了研究,结合全区地质背景,可以归纳为:区内Ag、Pb、W、Sn、Mo、Zn的异常规模较大,相对离散程度高、具有较好的成矿潜力。将优选出的综合异常进行评分排序,划分出保林工区北东854高地铅银找矿远景区、保林工区北东886高地金找矿远景区、四十八农场北西986高地钼钨找矿远景区。1：50 000 soil geochemical survey were carried out in Ur Khan area, Inner Mongolia. Distribution character of elements, single element anomalies feature, elements of the correlation analysis, anomaly characterized by a combination of elements were studied, combined with the region＇s geological background, can be summarized as follows： the Ag, Pb, W, Sn, Mo, Zn anomalies are in large scale, relatively high degree of dispersion, with good mineralization potential. According to selected consolidated anomalies rating sort, three prospect areas are pointed out： Northeastern 854 Highland in Baolin area for Pb-Ag; Northeastern 854 Highland in Baolin area for Au; Northwestern 986 Highland in No. 48 farm for Mo-W .
