Paleo-monsoon activities of Mu Us Desert, China since 150 ka BP - a study of the stratigraphic sequences of the Milanggouwan Section, Salawusu River area
The interbeddings of the aeolian sand dune facies and the fluvio-lacustrine and paleosol facies in the Milanggouwan stratigraphic section have been examined by a series of geological methods: including grain size, magnetic susceptibility, spore-pollen and fossil analyses along with various dating me...
