| 摘 要： | 塔里木盆地西南缘可划分为３ 个地层区和２ 个缝合带。该区自震旦纪来经历了两大构造旋回，发育３ 种类型的岩石组合。库地缝合带是库地洋经历了一次开合的遗迹，分离了西昆仑与塔里木这两个地层区。康西瓦缝合带是康西瓦洋经历了两次开合的遗迹，它分别是塔里木与羌塘两板块和西昆仑与喀喇昆仑两地层区的分界线。

| Abstract: | The southwestern of Tarim Basin may be divided into three straigraphic zones and two sutures.Since Sinian the region has undergone two big tectonic cycles,and three kinds of rock assemblages are developed.Kudi suture is a trace of paleo kudi ocean once experienced opening and closing,which is the boundary of West Kunlun and Traim.Kangxiwa suture is a trace of paleo kangxiwa ocean experienced twice opening and closing,and it is both the boundary of Kala Kunlun and West Kunlun and boundary of Qiangtang plate and tarim plate. |
