Abstract

According to the field investigation, observation by an electronic microscope and x-ray identification and chemical analysis, desert-steppe migration in the Loess Plateau at about 450 kaBP was studied. The development of gypsum indicating the desert-steppe environment, also indicates that the climate changed at 450 kaBP from monsoon climate to nonmonsoon climate in the Loess plateau, and the region was not affected by summer monsoon and was in the cold and dry environment of nonmonsoon climate. Annual mean precipitation was about 200 mm, 400 mm less at that time than at present
