Abstract:

The interrelation between geochemical behavior of some chemical elements and spacial distribution of clay minerals near the Great Wall Station,Antarctica,is studied in detail,and then the formation of clay minerals is discussed on the geochemistry. The results indicate that Ca and Mg are the principal factors controlling the formation of kaolinite and that the spacial distribution of kaolinite is affected by Ca and Mg.The geochemical behavior of Ca,Mg,Fe and especially Si is closely interrelated to the spacial variation of montmorillonite and the formation of montmorillonite is controlled by Si.
