| 摘 要： | 文章通过对近年来有关吉尔吉斯中天山研究进展的梳理,结合在吉尔吉斯斯坦的实地考察,系统论述了中天山基础地质情况,并简述与岩浆活动有关的成矿作用。吉尔吉斯斯坦境内的天山由"尼古拉耶夫线"和阿特巴什—伊内尔切克断裂划分为北、中、南3部分。中天山两侧的缝合带限定了早古生代古吉尔吉斯洋和晚古生代南天山洋的发展和消亡过程。组成中天山的不同块体大多具有古元古界的基底,古生代总体处于大陆坡-边缘海沉积环境。晚古生代产出与俯冲相关的岩浆作用和后碰撞岩浆作用,前者与斑岩型铜矿、接触交代型铜-金矿相关,后者与造山型金矿相关。

| Abstract: | Recent studies of Middle Tianshan Mountains are reviewed in this paper, with particular interest placed on magmatism and related mineralization. The Tianshan Mountains in Kyrgyzstan are composed of three major structural units, i.e., the northern, middle and southern Tianshan Mountains, which are separated by the Nikolaev Line and Atbashi-Inylchek fault. The suture zones on both sides of the Middle Tianshan Mountains were formed as a result of progressive subduction and subsequent closure of the Terskey Ocean in Early Paleozoic and the Paleo-Turkestan Ocean in Late Paleozoic. Various Precambrian continental domains joined to form the basement of the Middle Tianshan Mountains. The Paleozoic was generally a passive stage in the history of the Middle Tianshan Mountains. The Late Carboniferous magmatism had distinct metallogenic affinities with subduction-related rocks, and the post-collisional intrusions and orogenic Au deposits in the Early Permian were formed coevally and controlled by tectonics. |
