内蒙古东乌珠穆沁旗多金属成矿带位于内蒙古锡林郭勒盟东乌珠穆沁旗辖区内，是我国北部重要的银、铅、锌、铜、铁、钨、锡成矿带之一。成矿带内古生界火山-沉积岩地层发育齐全，华力西期至燕山期岩浆岩类型繁多，各时代构造形迹分布广泛，成矿地质环境优越，已发现和圈定各类金属矿床（点）78处。上泥盆统安格尔音乌拉组和石炭系宝力格庙组是本区多金属矿床的主要赋矿地层，华力西至燕山期构造一岩浆活动与多金属矿成矿作用关系十分密切，北东向的深大断裂为主干断裂是导矿构造，控制和限定了成矿带内岩体和多金属矿的分布及产出，北西、北西西和北东向的次级断裂是主要的成矿、容矿构造。北西、北西西向构造与北东向主干断裂交汇地段以及中酸性侵入体内部、边部、接触带是本区最主要的多金属找矿的有利部位。

Dong Ujimqin Banner metallogenic belt, located in the Xilinguole League, is one of the most impor-tant metallogenic belt of silver, lead, zinc, copper, iron, tungsten and tin in China. This region has distinguished metallogenic geological environment because of the completely developed Paleozoic volcanic and sedimentary strata, diversified magmatic rocks from Hercynian to Yanshanian period and complex structural features. 78 ore deposits(occurrences) have been discovered and delineated in this region. Upper Devonian Angeeryinwula Forma-tion and Carboniferous Baoligemiao Formation are the main ore-hosting strata. Tectonic-magmatic activities from Hercynian to Yanshanian period have close relationship with polymetallic ore-forming process. NE striking deep fracture is the main fracture and ore-transmitting structure, controlling and limiting the distribution and oc-currence of rock bodies and polymetallic ore deposits in the metallogenic belt, and NW, NWW and NE striking secondary fractures are the main ore-forming and-hosting structure. The intersections of NW and NWW striking structures and NE striking main structure and the interiors, margins and contact zones of intermediate-acid intru-sions are the main ore-prospecting targets in this region.
