摘要
Through comparing with the type Luochuan loess-palesol section of the Quaternary aeolian deposit in the Loess Plateau, the authors draw the following conclusions. The contents of major elements in the loess and paleosol at the Zhaosu section in the Ili region show similar variations, which indicate that both of them experienced the similar degree of chemical weathering after deposition. Major elements have the same changing trend as that of the Loess Plateau,with enriched CaO and MgO and depleted Na2O and P2O5. CIA index, Na/K ratio and A-CN-K diagrams all indicate that the Ili loess and paleosol experienced weaker chemical weathering than that in the Loess Plateau.
