| 摘 要： | 西南天山造山带可划分为伊犁中天山、中天山南缘、南天山和塔里木４个构造地层区。伊犁中天山区出露早元古代变质结晶基底及晚期地台型稳定盖层。中天山南缘区产出一套早古生代变质俯冲杂岩。南天山区早古生代为陆坡、陆棚相被动陆缘沉积，晚古生代发育洋壳建造。塔里木区北部出露中晚元古代“优地槽建造”的变质结晶基底和早震旦世后稳定盖层。

| Abstract: | The Southwestern Tianshan orogenic belt may be divided into four tectonostratigraphic regions, namely, the Yili-central Tianshan, the southern margin of the central Tianshan, the southern Tianshan and the Tarim. The early Proterozoic metamorphic crystalline basement and the late stable platform covers are exposed in the Yili-central Tisnshan region. A series of metamorphic subduction complexes crop out along the southern margin of the central Tianshan region. In the southern Tianshan region, early Paleozoic slope and shelf were deposited on the passive continental margin, and the Late Paleozoic oceanic crustal formation occur. The Middle-Late Proterozoic metamorphic crystalline basement and the postEarly Sinian stable covers are exposed in the north of the Tarim region. |
