Stable phases according to MELTS_Excel at (a) fixed pressure and temperature and variable oxygen fugacity and water contents, (b) fixed pressure and water content (5 mass%) and variable oxygen fugacity and temperature, and (c) fixed temperature and water content (5 mass%) and variable oxygen fugacity and pressure. Abbreviations are plagioclase (Pl), orthopyroxene (Opx), clinopyroxene (Cpx), olivine (Ol), biotite (Bt), and magnetite (Mag).
