Abstract:To further understand the relations between volumetric weight and the EastAsian monsoon evolution, we established volumetric weight sequences of loesspaleosols at the Luochuan section since 250 ka BP and Baicaoyuan section since 140 ka BP, respectively. Comparison between volumetric weight, magnetic susceptibility, particle size and deepsea oxygen isotope show that loesspaleosols volumetric weight in different climate regions east and west of the Liupanshan indicates different paleoclimate significance mainly controlled by different climate factors. Loesspaleosols volumetric weight is controlled by EastAsian summer monsoon in semihumid and semiarid region lying in east to the Liupanshan, whose values are influenced by pedogenesis, and by EastAsian winter monsoon in semiarid region west of the Liupanshan, whose values are influenced by particle size, and can be employed as a proxy indicator of summer monsoon evolution and winter monsoon evolution in the abovementioned two climate regions, respectively. Compared with sections in Baicaoyuan, Luochuan, Lingtai and Sanmenxia, volumetric weight values increase spatially from northwest to southeast in China, further indicating different influences of summer and winter monsoon on volumetric weight values of different climate region.
