| Abstract: | Based on the interpretation of satellite image,field investigation and geomorphic survey and sample dating of surface,the strath terrace and fill terrace at the outlet of Moleqiehe River on the western segment of Altyn Tagh Fault zone(ATF)are used to study the tectonic uplift rate,uplift model and aggradation rate,and cooperated with data of the regional climate,the response to climate evolution of development of terrace are discussed.The previous studies of the terraces related with the Altyn Tagh Fault zo... |
