Abstract:

This paper states that under lowtemperature, there exists the weak chemical weathering processes on the landsurface environment at Stornes Peninsula, Larsemann Hills,which has led to the enrichment and migration of chemical elements in variant degrees. The element of Ca has the strongest migrational ability, and Mg, Sr, Zn, K, Na, etc. have relatively strong migrational abilities. Elements have the variant characteristics of enrichment and eluviation in different particle size. The average ratio of SiO2/Al2O3 is 5.79 which shows a weak chemical weathering property of the soil. Comparing with the parent rock, the element of SiO2 and Al2O3 have been eluviated. In addition, there is the trend of increasingly strong weathering from south to north. Finally, the strength of the weathering crusts in middle and deep sections is slightly higher than that of surface section.
