| 摘 要： | 内蒙古自治区扎鲁特旗伊和布拉格多金属矿位于额济纳旗-大兴安岭成矿区之突泉-林西华力西燕山期铁（锡）铜、铅、锌、银、铌（钽）成矿带。区内共发现7条矿化蚀变带,土壤地球化学测量圈定了元素组合异常4个。矿化蚀变带受NE-SW向断裂构造控制,其中Ⅲ号矿化蚀变带、Ⅴ号矿化蚀变带位于该区近东西向和近南北向断裂带的交汇处。矿化蚀变主要产于下二叠统或上侏罗统,成矿作用与燕山中晚期岩浆侵入活动相关。矿化蚀变带与地球化学异常及低电阻率,高极化激电异常均相关性,其中Ⅲ号蚀变带深部已见多层银铅锌矿体。从地质、物化探资料分析并与有关同类型的矿床类比,区内多条矿化蚀变带均具有寻找中-大型银铅锌多金属矿潜力。

| Abstract: | polymetallic deposit in inner Mongolia is located within Tianshan-Xinmeng Orogenic system,in Daxing＇anling arc-basin system in hierarchy Ⅱ tectonic unit and in Linxi-Wulanhaote island-arc zone in hierarchy Ⅲ tectonic unit.It also lies in Tuquan-Linxihualixi Yanshanian Fe（Sn）-Cu-Pb-Zn-Ag-Nb（Ta） mineralization zone,Ejinaqi-Daxing＇anling district.Seven mineralization-alteration zones are marked,Geochemical anomalies are found in Au-Ag-Cu-Pb-Zn-Sn-Mo-As-Sb elements via 1：10000 soil geochemical survey with four composed anomalies,especially in Ag-Zn-Pb anomalies with clear concentration centers.No.Ⅲ and No.V zones are closed to geochemical anomalies.PE profile is a typical low-resistance-high-polarization,well consistent with geochemical anomaly AP2,which is produced by mineralization as confirmed by drilling.The mineralization-alteration zone,which is mainly controlled by NE-striking faults,of which No.III and No.V zones are located in the conjection between EW-and SN-striking faults.Metallic mineralization occurs in the lower Permian or the upper Jurassic Manketou＇ebo formation,most associated with Mesozoic （late Yanshanian period） magmatic activities. |
