  1. Strong negative 8 eu shows the granites are high evolved granite. ( 6 ) the tetrad effect of ree and the obvious fractionation between k - rb, y - ho, zr - hf, nb - ta, and sr - eu in the dajishan granites indicate that, the aqueous fluid pays an important role in the evolution of the granites, as well as indicate that there exist enough interaction between peraluminous melt and aqueous magmatic fluid. furthermore the fluorine played a very important role in this process
