摘要利用西天山那拉提山地区的核磁共振资料，结合锆石U-Pb年龄、Hf同位素组成、古生界侵入体主微量元素等资料，进行了综合研究，以提高对区域地球动力学演化的认识。根据年代学和地球化学资料，核磁共振将古生代侵入岩划分为480±5 Ma、445 ~ 410 Ma、345 ~ 320 Ma和295 Ma 4类，分别对应于(1)Terskey洋的闭合和南天山弧后盆地的打开，随后是南天山洋的打开，(2)南天山洋壳的初始俯冲，(3)主俯冲阶段，(4)碰撞-后碰撞阶段。继特尔斯基洋闭合后，南天山洋在早志留世开启，并在早石炭世末期俯冲至伊里—中天山之下。随后俯冲板块的断裂引发了大陆地壳的部分熔融，形成了核磁共振中体积较大的花岗质岩石。
A synthesis involving the data for the Nalati mountain region (NMR) in west Tianshan with a dataset including zircon U-Pb ages, Hf isotopic composition, major and trace elements of Paleozoic intrusions are presented to improve the understanding of regional geodynamic evolution. Paleozoic intrusive rocks in the NMR could be classified into four categories based on chronological and geo-chemical data: 480±5 Ma, 445-410 Ma, 345-320 Ma, and 295 Ma, which correspond to (1) closure of the Terskey Ocean and the opening of the south Tianshan back-arc basin, which was followed with the opening of the south Tianshan Ocean, (2) initial subduction of the south Tianshan oceanic crust, (3) major subduction stage, and (4) collision to post-collisional stage, respectively. Following the closure of the Terskey Ocean, the south Tianshan Ocean opened at Early Silurian and subducted under Yili-central Tianshan by the end of Early Carboniferous Period. The following breakoff of the subducted slab triggered partial melting of continental crust and formed voluminous granitic rocks in the NMR.
