Overview of initial liquidus plagioclase composition in molar An(%) for each MELTS model presented in this study at various lithostatic pressure, initial water content and redox condition. Missing values are either due to instability of MELTS at high water contents at low pressure (1–2 kbar) or the replacement of plagioclase with garnet at high pressure (≥6 kbar).
