| 摘 要： | 通过层序地层学的划分与对比，将侏罗系划分出8个沉积层序，层序界面以I型层序界面为主，沉积相类型主要为曲流河，辫状河、辫状三角洲，湖泊，沼泽化湖泊等5种，自晚三叠世塔里奇克期至白晋纪末，早三叠世形成的南天山褶皱隆起带开始遭受剥蚀，盆地基底反弹，盆地格局表现为宽缓，伸展的特点，沉积模式表现为潮湿气候下的冲积补偿和干旱气候下的冲积补偿2种方式。 |

| Abstract: | An investigation of sequence stratigraphy shows the Jurassic system in Kuqa Depression of Tarin basin can be divided into 8 sedimentary sequences, of which type I sequence boundary dominates. The sedimentary facies mainly consists of 5 types, such as meandering river ,braided river, braided river delta, lake and swamp lake. From Taliqike stage of late Triassic to the last stage of Cretaceous, the folded thrust band of south Tianshan formed in early Triassic started to be denuded , the basin basement started to return, the feature of basin structure was expanded and smooth.The sedimentary modes includes 2 types: one is alluvial compensation under damp climate , the other is alluvial compensation under dry climate. |
