摘　　要：在西天山晚古生代吐拉苏火山盆地内,由于火山物质、构造、流体、成矿环境的差异,形成了不同类型的阿希金矿、伊尔曼得-吉兰德金矿和塔吾尔别克金矿,构成了成矿系列,成矿系列中的各类矿床成矿机理具有相关性、独特性和规律性。In Late Paleozoic Tulasu volcanic basin of Western Tianshan, the Axi gold deposit, Yiermande-Jilande gold deposit and Tawuerbieke gold deposit were formed in different types, because of the differences in volcanic products, structure, fluid and mineralization environment. These deposits composed a metallogenic series, with relativity, distinction and regularity in metallogenic mechanism. In this area, the kaolinite-barite type (silicated rock type) of gold deposits were formed in the early stage of volcanism; while the adularia-sericite type, in the late stage; the porphyry type, in post-volcanism activity.
