摘　　要：内蒙古东乌旗查干敖包图地区位于二连—东乌旗成矿带东段,处于燕山期断裂附近脉岩群中的高温热液型Pb、Zn、Ag多金属矿床的有利区域,具有良好的成矿地质背景。区内1︰5万及1︰1万土壤地球化学异常元素主要为Pb、Zn、Ag、Cd、W、Mo等,浓集中心明显,套合较好,1︰1万地面高磁异常与北东向构造岩将活动密切相关。通过1︰1万地质、土壤、高磁扫面和地物化特征综合研究显示,查干敖包图一带具有热液型Pb、Zn、Ag多金属矿成矿远景。Study area belongs to the east of Erenhot -East WuZhuMuQin Banner metallogenic belt and is located in the region for high-temperature-hydrothermal Pb-Zn-Ag polymetallic deposits formed in vein groups nearby Yanshanian fault. There is high metallogenic potential in the study area. Both of 1/50000 and 1/10000 synthetical pedogeochemical anomalies consist of Pb, Zn, Ag, Cd, W, Mo and other elements. Concentration centers are obvious and the single element anomaly nests well with each other. The 1/10000 ground high-precision magnetic anomalies are closely related to NE-striking tectonic-magmatic events. Through 1/10000 geological, pedogeochemical, high-precision magnetic survey and comprehensive research, we can find that there is high potential for hydrothermal-type Pb-Zn-Ag polymetallic mineralization in the study area.
