One is the evolutional model of magmas with different parents, which occurred in the Huashan composite granitic plutons, and the Meihua supplementary granite might have resulted from derivative liquids segregated from fractional crystallization of magmas equivalent to Huashan magmas.

(2)The main lithogenetic pattern of granitoids rock masses is fractional crystallization.

Experiments of fractional crystallization under high T P conditions demonstrate that during crystallization of F bearing alumina oversaturated granitic magma, an evolutional trend of REE concentrations in fluid phase coexisting with melt phase is observed: When temperature drops from 750℃ down to solidus (about 570℃), the REE concentrations gradually decrease.

In this paper a new approach-graphic interpretation of and (or) lgC-lgC will besubmitted to obviously discriminate two magmatic processes including mantle equilibrium partialmelting and magmatic fractional crystallization.

The characteristics of geology,petrography and geochemistry indicate that they were formed by same source magmacrystallization differentiation.
