摘　　要：通过对内蒙古自治区巴林左旗下盖家店多金属矿的综合研究发现,矿体赋存于侏罗系白音高老组角砾凝灰岩和沉凝灰岩中,呈细脉状及稀疏浸染状分布,属于蚀变岩型矿体。围岩蚀变较发育,以褐铁矿化、黄铁矿化、高岭石化为主。通过对该矿体的构造背景、成因类型以及地质特征进行阐述,为该区域今后找矿具有重要指导意义。Through comprehensive study of the polymetallic ore in the Xiagaijiadian of Bairin Left Banner of Inner Mongolia Autonomous Region, it is found that the ore bodies occur in the Jurassic Baiyin Gaolao group breccia tuff and sedimentary tuff, its distribution was veined and sparsely disseminated, which belongs to the altered rock type ore body. The wall rock alteration is more developed, mainly dominated by brown iron mineralization, pyrite mineralization and kaolinnization. The structural background, genetic type and geological features of the ore body are expounded, which has important guiding significance for the future prospecting in this area.
