摘要
In this paper, the authors have analyzed loess magnetic susceptibility and grain sizes along the Zhaosu section in Ili basin of Xinjiang dominated by the westerlies, and discussed the differences in the enhancement mechanism of magnetic susceptibility of the Ili loess. Studies show that although the content of fine clay is higher in the Ili loess than that in the loess plateau, the contribution of fine components to the loess magnetic susceptibility is very limited, suggesting that the magnetic carriers in the study area exist mainly in the coarse components. The authors hold that the mechanism of susceptibility formation in the Ili loess can be interpreted as either Alaska wind model or pedogenesis model of the Chinese Loess Plateau.
