| 摘 要： | 内蒙古东珺银铅锌矿床是大兴安岭东乌旗—兴安成矿带内新发现的脉状银铅锌矿。通过分析该矿床地质特征、矿体特征及控矿因素,总结了其矿化富集规律,初步探讨了矿床成因。该矿床赋存于中侏罗统塔木兰沟组构造裂隙中,NW向构造是矿区的主要控矿构造;成矿与晚侏罗世—早白垩世火山和次火山热液活动密切相关,属火山-次火山热液型矿床。

| Abstract: | Dongjun Pb-Zn-Ag deposit occurs in Dongwuqi-Xingan metallogenic belt in Daxinganling.It is one of the newly discovered vein-type deposits in the metallogenic belt.It is also a major breakthrough in ore prospecting in the grassland-covered area.In this paper geological characteristics of the deposit,ore body and ore-controlling factors are analyzed then the mineralization enrichment regularity summarized and it＇s genesis discussed.The deposit occurs in the structural fissure of the Middle Jurassic Tamulan formation and is mainly controlled by the NW structure.Genetically it is closely related to the late JurassicEarly Cretaceous volcanism and the hydrothermal activity thus belongs to volcanic-sub-volcanic hydrothermal deposit. |
