摘　　要：花敖包特大型脉状银铅锌多金属矿床赋存于下二叠统寿山沟组(P1s)裂隙破碎带中,属中低温次火山热液成因.矿床处于大兴安岭中南部的锡林浩特-霍林郭勒多金属成矿带上,断裂构造发育,火山活动强烈,银铅锌多金属多期成矿.矿体赋存于北西、北东及近南北向的构造破碎带里,矿体呈脉状严格受断裂构造控制.矿体规模中等,形态较复杂,厚度较稳定,组分较均匀.围岩蚀变发育,可出现3期,具明显的分带性.成矿期为晚侏罗世.The large-scale Huaaobaote vein type of Ag-Pb-Zn polymetal deposit in Xi Ujimqin Qi, Inner Mongolia, occurring in the fracture zone in Lower Permian Shoushan formation, is of subvolcanic meso-epithermal genesis. The deposit is located in the Xilinhot-Huolin Gol polymetal metallogenetic belt in the middle-south of Daxinganling Mountains, with developed faults and intense volcanic activities.The metallogenesis of Ag-Pb-Zn polymetal is in multiple stages. The vein-shaped ore bodies are in medium scale, complex shapes, stable thickness, evenly distributed components, and controlled by NW-, NE- and N-S-trending faults. The wall-rock alterations are developed in 3 stages, with obvious zonation. The metallogenie epoch is Late Jurassic.
