The Analysis and Discussions on the Chronological Frame of Jinshajiang River Valley-Drainage
详细信息   
摘要


     On the basis of our new geomorphologic, lacustrine and environmental feedback records and a reassess-ment of published date, the chronological framework of the evolution of Jinsha River valley drainage is reconstruc- ted. We suggest that the history of the Jinsha River valley drainage formation can be divided into 3 stages, namely embryonic stage from the Pliocene to Early Pleistocene, initial development stage from the end of Early Pleisto- cene to Middle Pleistocene and shaping stage later Pleistocene, and also propose the landforms pattern of Jinsha River including Dry-hot Valley should appear around the end of Early Pleistocene.
