Fig. 9From: The responses of the four main substitution mechanisms of H in olivine to H2O activity at 1050 °C and 3 GPaVariation of molar H2O concentration with molar Ti concentration for [Ti] experiments conducted both at both constant \( {a}_{{\mathrm{H}}_2\mathrm{O}} \) but variable at Ti concentration and variable in \( {a}_{{\mathrm{H}}_2\mathrm{O}} \) and constant in bulk Ti concentration. The dashed line represents 1:1 molar concentrationsBack to article page
