The chief aim of this study is to investigate the chemical weathering process of the weathering crust in Great Wall Station region of China (in Fildes Peninsula), Antarctica by the method of sedimentology. CW,SW,GW,TW,WE weathering crusts developed on volcanic clastic rock, gray aptitic basalt with tuff or basaltic bedrock. On change of minerals, geochemical behaviors of elements, migration and enrichment regularities of elements. Correlation between element geochemical behaviors, change of weathering potential of rocks in chemical weathering process are studied by us. We can see that the sequence for weathering strengths of the abovementioned sections, from high to low, should reflect in TW,GW,CW and SWT and basical correspond with that calculated from the enrichment and differentiation indexes.
