| Abstract: | Using the main component analysis,this paper deals with the argillification of the albic soils. It is concluded that the chemical composition of the clays relates to the mineral composition. The clay mineralogy feature shows that under the illuvial conditions, montmorillonite can change into kaolinite, and the formation of the argillic horizons involve two processes: one is the desilicification - allitization and argillification, and the second is the clay accumulation. |
