Relationship between fugacity of H2O, fH2O, and species abundance. a Proportion of OH and molecular H2O as a function of fH2O in NA10–H2O fluid from Mysen (2010) (open symbols). Solid symbols plotted onto the line are the date from the current silicate–C–O–H–N fluid. In both cases, the silicate starting composition is NA10. See text for discussion of approximation of OH/(OH + H2O) ratio with the FTIR absorbance ratio, A4500/(A4500 + A5200). Silicate polymerization of melt, NBO/T, as a function of fH2O in NA10–H2O fluid from Mysen (2010) (open symbols). b Evolution of NBO/T of the silicate component in the fluid as a function of temperature. Solid symbols plotted onto the line are the data from the current silicate–C–O–H–N fluid. In both cases, the silicate starting composition is NA10
