摘　　要：概要介绍了哈萨克斯坦阿尔泰巨型成矿带的构造背景、地质特征、成矿规律、典型矿床特征及成矿模型。矿山阿尔泰是世界上著名的海相火山岩型块状硫化物（VHMS）铜-铅-锌多金属矿富集区，已发现十几个大型和超大型矿床。VHMS型矿床形成于泥盆纪裂谷发育阶段，赋存于玄武岩-流纹岩双峰式火山岩和陆源碎屑沉积岩中。与成矿有关的火山岩主要为中泥盆世吉维特期（380～370Ma），部分为早泥盆世和晚泥盆世。泥盆纪之后的大陆边缘俯冲、碰撞、岩浆热液活动，对裂谷阶段形成的VHMS型矿床进行不同程度的叠加改造。在早二叠世形成了与花岗岩有关的钨、锡，铌、钽、锂等稀有金属矿化。This paper briefly introduces the tectonic environment, geology, metallogeny, typical mineral deposits and metallogenic model of the Altay metallogenic belt in Kazakhstan. The Rudny Altay in Kazakhstan is an important VHMS （volcanics-hosted massive sulphide deposit ） type of copper--lead--zinc polymetallic metallogenic belt in the world, and hosts tens of large and superlarge deposits. VHMS type of the copper-- lead--zinc polymetallic deposits was formed in a riftogenic stage. They occur in basalt--rhyolite bimodal volcanic rocks and terrigenous elastic sediments. The ore-related volcanism is mostly in the Givetian （380 370 Ma）, with some in the Early Devonian and Late Devonian. After the Devonian, remobilization, transportation, and redeposition in many stratiform deposits of the Rudny Altay formed during the riftogenic stage are associated with subduction, collision and magmatism on the continental margin. Granite-related W, Sn, Nb, Ta, Li and rare metal deposits formed in the Early Permian.
