摘　　要：研究区位于塔里木西南缘盆山结合带的喀什坳陷,新生代以来沉积了巨厚的海相及湖盆相地层。通过对野外实测剖面开展系统的沉积相分析及层序划分研究,并结合粒度分析,还原出新生代以来沉积盆地发展、演化过程。认识到新生代以来盆地的演化与印度、欧亚板块之间覆冲、拼合、碰撞以及青藏高原隆升有很好的耦合关系,同时从侧面也验证了青藏高原快速隆升的时间结点应在上新世末期之后。The study area lies in the Kashgar depression of basin-range junction belt on south- western margin of Tarim Basin. From Cenozoic, extremely thick marine and lake-basin strata have accumulated there. Systematic study including sequence stratigraphy and facies analysis has been conducted on the field measured cross sections. Combining with the grain size analysis, this paper reconstructs ic.
