摘　　要：东乌旗位于内蒙古自治区锡林郭勒盟东北部,该区构造形迹复杂,岩浆活动频繁,多金属矿床(点)星罗棋布,是我国重要的金、银、铜、铅、锌、钨、钼等多金属成矿区。NE、NNE向断裂为控矿构造,区内褶皱、断裂发育,为成矿提供了导矿、容矿构造。陆相火山—次火山岩及中生代二长花岗岩体的发育为矿产的形成提供了必要的热源和物质来源。综合分析,认为该区是寻找与中生代火山岩浆活动有关的金、银、铜多金属矿的有利地区,是蚀变岩型和岩浆热液型金属矿床赋存的有利部位。Dongwuqi area is located in the northeast of Inner Mongolia,the structural feature is complex and magmatic is activity in this area,polymetallic deposit spread everywhere,it is an important gold,silver,copper,lead,zinc,tungsten and molybdenum mining area.NE,NNE trending faults are ore-controlling structures,the fold and fault provides leading ore structure.The development of continental volcanism-subvolcanic and Mesozoic monzogranite provide the necessary heat and material sources for the forming of mineral.Comprehensive analysis,we think that the area is the favorable area looking for gold,silver,copper and polymetallic deposits which are related to magmatic activity,also it is the favorable position of occurrence of altered rock type and magmatic hydrothermal type polymetallic deposit.
