| 中文摘要:古亚洲洋演化过程中在兴蒙造山带中形成了大量金属矿床。早古生代早期，古亚洲洋向北俯冲，形成了奥陶纪多宝山-铜山斑岩Cu-Au成矿系统；早古生代晚期，古亚洲洋向南俯冲并形成了晚奥陶世白乃庙Cu-Mo-Au成矿系统和志留纪别鲁乌图海底喷流块状硫化物成矿系统。古亚洲洋在晚古生代早期向北俯冲，形成了晚泥盆世欧玉陶勒盖Cu-Au成矿系统。基本同时，古亚洲洋向南俯冲，形成了晚泥盆世哈达门沟Mo成矿系统。早石炭世，研究区构造体制从岛弧环境逐渐转变为陆内伸展环境，并在此过程中形成了豆荚状铬铁矿成矿系统和小型斑岩Mo-Cu成矿系统。 |

| Abstract:Abundant metal deposits formed during the evolution of the Paleo-Asian ocean in the Xing-meng orogenic belt. The northward subductions of the Paleo-Asian ocean during the early Early Paleozoic formed the Ordovician Duobaoshan-Tongshan Cu-Au porphyry ore-forming system. The southward subductions of the Paleo-Asian ocean during the late Early Paleozoic formed the late Ordovician Bainaimiao Cu-Mo-Au ore-forming system and Silurian Bieluwutu VHMS ore-forming system. During the early Late Paleozoic, the northward subductions of the Paleo-Asian ocean formed the late Devonian Oyu Taolgoi porphyry Cu-Au ore-forming system. In the same period, the southward subductions of the Paleo-Asian ocean formed the late Devonian Hadamengou Mo ore-forming system. Tectonic pattern changed to extensional environment during Early Carboniferous periods, and formed podiform chromite and small porphyry Mo-Cu ore-forming systems. |
