EXPERIMENTAL STUDIES OF PARTIAL MELTING OF MASSIVE GRANITES

Lin Qiang Wu Fuyuan (Changchun University of Earth Sciences,Changchun,130061)  
Phase equilibrium relations in the melting granite system are the basis ofmodern petrology.At present this phase-equilibrium theory has been establishedon the basis of the results of melting experiments on powder samples.Becauseof the destruction of the original fabrics,the experiments cannot provide eviden-ce for variations in mineral composition,fabric,composition and distribution of melt,so they have many limitations in petrogenesis.Experimental results indicated thatthe melts exist mainly at the boundaries of quartz/plagioclase and quartz/potash fel-dspar,their compositions being essentially controlled by local melting systems amongdifferent minerals and having nothing to do with the bulk composition of the rock.At lower temperatures(740—760℃,0.2GPa),the melt plots at or near the eutecticpoint in the Q-Ab-Or-An-H_2O diagram,revealing a mechanism of equilibrium mel-ting.At higher temperatures(790—800℃,0.2GPa),the melt becomes lower inSiO_2 and higher in Na_2O,it is not situated on the eutectic line in the Q-Ab-Or-An-H_2O diagram,but at the same time no mineral disappeared due to melting,sug-gesting that the melting at higher temperatures is of nonequilibrium.It is obviousthat the phase-equilibrium relations in natural massive granite samples are greatlydifferent from those in powder samples,which would provide new clues to thephase-equilibrium relations in the granite system.
