摘　　要：内蒙古东乌旗乌里雅斯太银多金属矿主要是通过1∶1万土壤地球化学测量发现的。区内成矿类型有两类,一为充填交代脉状铅锌(银)矿,与燕山早期中细粒花岗岩关系密切,次级断裂或构造裂隙为控矿断裂。一为构造蚀变岩型,成矿物质来源可能为格根敖包组,找矿部位为东西向、北东向构造蚀变带。Silver polymetallic deposit in Uliastai of Dongwuqi in Inner Mongolia was discovered mainly by means of 1 ： 10, 000 soil geochemical survey. There are two types this area, including filling metasomatic vein lead-zinc （silver） deposit that is the early Yanshanian fine-grained granite and the mineralization is controlled by of mineralization in closely related with secondary fissures, tectonic faults and tectonic altered rock type, in which the ore-forming material might be from the Gegenaobao Formation. Structural alteration zones in east-west and north-east directions are favora- ble for ore prospecting.
