Changes in hydrogen and carbon isotope ratios of melts in equilibrium with fluid in melts equilibrated at 1400 °C and 2 GPa with the hydrogen fugacity controlled at the IW-H2O buffer. a D/H change expressed as a function of speciation of dissolved water relative to that of composition NS5 (Na2O · 5SiO2). (data from Mysen and Fogel 2010). b Changes in carbon isotope ratio in melts relative to composition NS5 (Na2O · 5SiO2) as a function of speciation of reduced carbon species (data from Mysen et al. 2009)
