Abstract

Abstract: The field investigations,g rain-size analysis and magnetic susceptibility measurement in the Holocene loess profiles in Qishan,Shaanxi,has revealed the characteristics of the climatic change during last 11000 years.There is an arid phase existed in the middle of the Holocene Mega thermal between 6 0005 000 a B.P..It is represented by a layer of loess(Lx) in the profile.Therefore,there are two pedogenic periods in the Holocene,which is represented by palaeosol S₀² and S₀¹ in the profile.In addition,smaller-scale climatic variation was very frequent over the last 11 000 years.

Key words: Holocene, climatic change, high resolution
