High-pressure partial melting and its relationship to the granulite facies metamorphism: Implications for the origin of felsic high-PT granulites in the Bohemian Massif, central Europe
Felsic granulites from the Moldanubian zone exhibit modal layering and discordant leucocratic veining, which suggest partial melting along the exhumation path from the eclogite to granulite facies. conditions. Mineral assemblages and garnet chemical zoning constrain a prograde metamorphic path that reach muscovite dehydration melting where the partial melt has crystallized. The goal of the thesis is to determine phase formation and melt productivity independently by experiments in the piston-cylinder apparatus and by thermodynamic calculations and phase equilibrium.
