Abstract: In this work, the late Cenozoic aeolian deposits at Huangshui catchment, the northeastern Tibetan Plateau, is investigated on geochemistry distribution and magnetic property, and, they are compared with that of the aeolian sediment in the Central Loess Plateau.It shows that the dust sources of the aeolian deposit in Huangshui catachment are different from that of the aeolian deposits in the Central Loess Plateau. The arid and/or semiarid region in the middle and west parts of the Tibetan Plateau may be a potential dust source for the aeolian deposit of the northeastern Tibetan Plateau. Therefore, the existence of the late Cenozoic aeolian deposit demonstrates that the middle and west parts of the Tibetan Plateau have been dry since the middle Miocene time.
