Detailed \nmagnetostratigraphy of a recently recovered 125-m-thick sediment \nsequence from the central Chinese Loess Plateau shows that the red \nclay began to accumulate at ca. 8.1 Ma, implying a marked drying in \nthe interior of Asian as well as the initial establishment of the \nEast Asian paleomonsoon regime. Prior to 3.8 Ma, the ferromagnetic \nmineral concentrations, as revealed by both magnetic susceptibility \nand S-ratios, exhibit a cyclic pattern superimposed upon a linear trend. \nThis pattern collapsed immediately after 3.8 Ma, suggesting a change \nin source area. This in turn may have resulted from the reorganization \nof atmospheric circulation and the onset of the modern Asian monsoon, \nprobably associated with the accelerated uplift of the Tibetan Plateau \nto a certain threshold elevation.\n\n","author":null,"citation":"Song, Y.G., X.M.
