In this paper,the soil chronological method and its dating principle as well as present research situation at home and abroad and developmental prospect for application are introduced and discussed in detail.The fundamental train of thought of this method has been applied by the authors to dating study of the foreland regions of the Yumushan mountain and Altun mountain,and four quantitative relational expressions between CaO,CaCO3 content and CaCO3 accumulation index value in soils and their developmental age have been preliminarily formed and the mean accumulation rate of the calcic coats on gravels in soils has been obtained by statistical calculation as well.Through test and comparative analysis,it is considered that the soils chronological method is applicable to the Northwestern region of China and has the vast prospects for application.
