The transition from carbonate to silicate melts in the CaO-MgO-SiO2-CO2 system
The compositions of melts in equilibrium with a lherzolite mineral assemblage were determined in the analogue system CaO-MgO-SiO2-CO2 at 3 GPa. Carbonate liquids coexist with olivine and two pyroxenes between the solidus for carbonated lherzolite at 1250°C and 1450°C. The Ca/(Ca + Mg) ratio of these...
