  1. Qz, quartz; Ab, albite; Or, orthoclase; C, corundum; Ne, nepheline; ASI, Al2O3/(Na2O + K2O) in moles. Density of aqueous fluids and pressure were calculated by equations of state of H2O (Haar et al. 1984) or saline solutions (Zhang and Frantz 1987). H2O concentrations in the melts were estimated by Moore et al. (1998). Anhydrous glass and hydrous melt densities were calculated by Bottinga and Weil (1970) and McBirney (1984), and Bureau and Keppler (1999), respectively. Major element compositions were recalculated to 100 total oxides. Raw total oxides were lower than 100 mainly due to H2O abundances in quenched glasses.
