| 摘 要： | 西天山造山带位于哈萨克斯坦—准噶尔板块与卡拉库姆—塔里木板块的结合部,是由一系列前寒武纪微陆块、古生代洋壳残片及陆缘弧相互拼贴而成的多聚合带、多成矿带,其独特的造山-成矿过程受到了国内外的广泛关注。本文通过构造单元划分与编图,建立了古生代西天山造山带的构造格架,认为古生代西天山造山带的构造演化依次经历了:罗迪尼亚大陆裂解与北天山早古生代多岛洋盆形成阶段(Z-O_2),北天山早古生代多岛洋盆闭合与南天山洋盆开始形成阶段(O_3-S),南、北天山洋晚古生代洋盆形成与发展阶段(D-C_1),南、北天山晚古生代洋盆全面闭合与天山碰撞造山带形成阶段(C1-C_2)和碰撞后板内演化阶段(C_2-P)。

| Abstract: | Western Tianshan Orogen, located in the conjunction of the Kazakhstan-Junggar Plate and the Karakum-Tarim Plate, has been regarded as the collision zone and metallogenic zone consisting of a series of Precambrian blocks, Paleozoic oceanic crust, and continental marginal arcs. The study of the orogenic-metallogenic processes of western Tianshan Mountain have received extensive attention. In this paper, the authors established the tectonic framework of western Tianshan Orogen in the Paleozoic on the basis of the tectonic division, and proposed a five-stage model of the tectonic evolution in Paleozoic:Rodinia supercontinental breakup and the formation of the early Paleozoic archipelagic ocean in northern Tianshan Mountains (Z-O2), closure of the early Paleozoic archipelagic ocean in northern Tianshan Mountains and the incipience of the southern Tianshan oceanic basin (O3-S), formation and development of the northern and southern Tianshan oceanic basins in the late Paleozoic (D-C1), closure of the northern and southern Tianshan oceanic basins and the subsequent formation of Tianshan orogenic belt (C1-C2) and, finally, the post-collision stage of the intraplate environment (C2-P). |
