摘　　要：花敖包特铅锌银矿床位于大兴安岭西乌珠穆沁旗地区,属于大兴安岭的南部的西坡褶皱带,紧邻松辽盆地。该地区的构造环境主要是古亚洲构造与环太平洋构造的迅速转换和激烈叠加形成,这就使得这一地区成矿的条件非常好,构造环境十分优越。在晚侏罗世至早白垩世成矿的花敖包特矿区主要是以银矿、铅矿、锌矿为主,产状基本为脉状。研究内蒙古花敖包特矿床花岗岩构造环境与动力学背景分析,对于评价内蒙古银铅锌矿床的潜力,以及认识内蒙古境内矿床的形成、演化的地球动力学环境均具有重要意义。The geographical position of Huaaobaote lead-zinc-silver deposit is in the Xiwuzhumuqi Banner area of Daxing’anling, which belongs to the western slope fold belt in the south of Daxing’anling, and is adjacent to the Songliao Basin. The tectonic setting of the area is mainly the rapid transformation and intense superposition of the paleo-Asian structure and the Pacific Rim structure, which makes the mineralization conditions in this area very good and the tectonic environment is very superior. The Huaaobaote mining area in the Late Jurassic to Early Cretaceous mineralization is mainly composed of silver ore, lead ore and zinc ore, and the occurrence is basically vein-like. The study of the tectonic environment and dynamic background of the Huaaobaote deposit in Inner Mongolia is of great significance for evaluating the potential of the Inner Mongolia silver-lead-zinc deposit and understanding the geodynamic environment of the formation and evolution of the deposits in Inner Mongolia.
