Through sampling and analyzing of granitic rocks and their overlying residual soil, the content changes of both the major and trace elements at the surface environment have been determined and the characteristics of granite weathering and the rules of element mobilization have been studied. In the soil, the average contents of Ti, Mn, Co, Cu, Mo, V and Zr are higher than those in the rocks, while the average contents of Al2O3, CaO, Na2O, K2O, Sr, Th and U are lower than those in the rocks, and other elements are almost the same. Generally, the lithophile elements showed strong activity in the weathering process while oxyphile elements are more stable with a weak activity. The activity of the chalcophile elements falls in between.
