- KD of the melt inclusions in olivines = (X(ol-Fe)/X(ol-Mg))/(X(liq-FeO)/X(liq-MgO)). X(ol-Fe) and X(ol-Mg) are mol fractions of fayalite and forsterite in olivine, and X(liq-FeO) and X(liq-MgO) are cation fraction of Fe(+ 2) and Mg in the melt. The mol fraction ratio of Fe(+ 2) to total Fe in the melt was assumed to be 0.8. At equilibrium, this KD is 0.299 ± 0.053 for P<2 GPa (Putirka 2008)
- KD of the clinopyroxene-hosted inclusions = − (X(cpx-Fe)/X(cpx-Mg))/(X(liq-FeO)/X(liq-MgO)). X(cpx-Fe) and X(cpx-Mg) are mol fractions of forsterite and enstatite in clinopyroxene, and X(liq-FeO) and X(liq-MgO) are cation fraction of Fe(+ 2) and Mg in the melt. The mol fraction ratio of Fe(+ 2) to total Fe in the melt was assumed to be 0.8. At equilibrium, this KD is 0.28 ± 0.08 (Putirka 2008)
- FeOt, total FeO; nd, not detected; na, not analyzed
- ax/y: x, analyzed by SIMS, y, analyzed by EPMA. The analytical errors is ± 0.2 wt% for SIMS (Saito et al. 2010) and ± 1 wt% for EPMA
- bThe analytical error is ± 0.0028 wt% (Saito et al. 2010)
- cMol fractions of S(+ 6) in total S in the melt inclusions calculated from the S Kα radiation wavelength measured by EPMA, assuming that all S in the inclusions is composed of S(+ 6) and S(− 2)
- dCalculated from the mol fraction of S(+ 6) in total S in the inclusions by Wallace and Carmichael (1994), assuming temperature of 1079 °C
- eCalculated from the oxygen fugacity and chemical composition of the inclusions by Kilinc et al. (1983), assuming temperature of 1079 °C
- fEstimates with 1079 °C
- gSaturation pressures calculated from H2O and CO2 contents of the melt inclusions using the solubility model of Papale et al. (2006). An online version of the Papale’s solubility model (http://melts.ofm-research.org/CORBA_CTserver/Papale/Papale.php) was used for these calculations. The mol ratio of Fe(+ 2) to total Fe in the melt and temperature was assumed to be 0.8 and 1079 °C, respectively
- hTemperatures of the melt inclusions in plagioclases were estimated from chemical compositions of the melt and their host phenocrysts using plagioclase–liquid thermometer by Putirka (2008, Eq. (24a)). This thermometer yields a standard error of estimate (SEE) of 36 °C. Temperature of the melt inclusions in olivines was estimated from chemical compositions of the melt and their host phenocrysts using olivine–liquid thermometer by Putirka (2008, Eq. (22)). This thermometer yields SEE of 29 °C. Temperature and pressure of the melt inclusions in clinopyroxenes were estimated from chemical compositions of the melt and their host phenocrysts using clinopyroxene–liquid thermobarometers by Putirka (2008; Eqs. (31) and (33)). These thermobarometers yield SEE of 42 °C and 290 MPa. Saturation pressures and H2O contents of the melt inclusions analyzed by SIMS were used for this calculationin. If the saturation pressures were not determined, pressure of 100 MPa was assumed. If the inclusions were not analyzed by SIMS, the H2O contents analyzed by EPMA were used
- iKD of the melt inclusions in plagioclases = X(pl-Ab)X(liq-AlO1.5)X(liq-CaO)/(X(pl-An)X(liq-NaO0.5)X(liq-SiO2)). X(pl-Ab) and X(pl-An) are mol fraction of albite and anorthite in plagioclase, and X(liq-AlO1.5), X(liq-CaO), X(liq-NaO0.5) and X(liq-SiO2) are cation fractions of Al, Ca, Na and Si in the melt (Putirka 2008). At equilibrium, this KD is 0.10 ± 0.05 for T < 1050 °C, and 0.27 ± 0.11 for T ≥ 1050 °C (Putirka 2008)
