Abstract

Taking Zhaoxiayu section,Mangshan,Zhengzhou as an example,this paper has studied the volumetric weight of loess-palaeosol sequences and its relation with susceptibility as well as its grain size.It is shown that volumetric weight bears an evident positive correlation to the summer monsoon variations indicated by the susceptibility,an evident inverse correlation to the winter monsoon variations indicated by the content of coarse fraction,and the natural compaction contributes very little to volumetric weight of loess-palaeosol sequences above S₁₀.Volumetric weight can thus be regarded as an indicator to the variations of the combination of winter monsoon and summer monsoon.
