Abstract

Chinese loess-paleosol sequence has provided the most detailed terrestrial records of climate changes in Quaternary. The aeolian sand and dust has been taken as an important proxy of expansion and contraction of the desert during geological period. The signals of the desert evolution were well p reserved in the aeolian deposits on the margin of the desert, which are effective to reconstruct the desert expansion and contraction. According to the dominantwind direction, generally NW-SE, we systematically studies 24 sections ofMalan loess in the west of Chinese Loess Plateau during the Last Glacial period. Detailed granular analyses show the properties of temporal and spatial of theMalan loess, and reducing of the percentage of the sand from northwest to southeast. Our study indicates that the proxies such asD [ 4, 3 ] , the fraction > 40μm (%) , the fraction > 63μm (% ) , and theMode are more sensitive than any other proxy. A new linear correlation model of sand percentage and distance are established, which shows different pattern to the east of the Chinese Loess Plateau.
