Influence of the Crystallization Temperature and Atmosphere on the Equilibrium Phase Assemblage of Plutonic Rocks of the Monzonite Family

详细

The influence of external settings on the mineral assemblage of plutonic rocks is studied. The equilibrium compositions of phases formed during melting–crystallization of quartz monzodiorite are calculated by physicochemical modeling (PCM) methods. It is shown that, by changing the temperature and atmosphere of melt formation, one can change the mineral assemblage of the crystallizing solid phase that can be used in stone casting and in the production of mineral fibers.
