| Abstract: | The Early Pleistocene rapid uplift of the Tibet plateau plays an important role to global climate change,formation of basin-range geography and appearance of desertification in Western China.Detailed grain size analysis and 36Cl dating have been carried out on the Early Pleistocene fluvio-lacustrine sediments of the Dunhuang basin in northeastern Tibet plateau.Results show that the Dangjinshan Mountains rose rapidly at the end of the Early Pleistocene(1.164-1.087 Ma B.P.),and gravels and coarse sandstones w... |
