Results show that the Spiti shale in Zanskar terminated 15Ma later than that in southern Tibet, while the lowermost Cretaceous quartz sandstone in Zanskar appeared 18Ma later than that in southern Tibet. The age of volcanic sandstone in southern Tibet is very poorly time constraint and their deposition occurred somewhere within Berriasian~early Albian. In Thakkhola, the Chukh Group volcanic sandstone are of late Hauterivian-early Albian age (duration about 20Ma), while in Zanskar, the volcanic sandstones facies only appeared in Albian (duration of less than 10Ma). Therefore, it can be concluded that the onsets of both quartz sandstone and volcanic sandstone occurred earlier in eastern Tethys Himalayas than in western Tethys Himalayas .

侏罗纪末~白垩纪初印度大陆的北缘同时期存在大陆向上挠曲,导致陆源碎屑输入量的快速增加,石英砂岩广泛存在;早白垩世火山岩屑砂岩对应着的印度大陆北缘地层侵蚀加深,使得较深部的深成火山岩暴露并遭受侵蚀;石英砂岩和早白垩世岩屑砂岩所代表的印度大陆剥露时间在空间上的&东早西晚&,说明构造运动首先是从特提斯喜马拉雅的东部开始(大印度与澳大利亚的彻底分离),然后逐渐波及西部的,东西时间差为15~20Ma;由于地壳均衡作用,大陆分离后原先地壳挠曲转变为地壳下沉,发生强烈的构造沉降,故Albian之后沉积一套深水环境下的海绿石、磷酸盐和黑色页岩沉积。
