N2 - Diamond-hosted inclusions provide information on the composition of the upper mantle. Many researchers found molecular CO2 inclusions, along with mineral and melt ones, in diamonds. Available experimental data on simplified systems suggest that CO2 fluid cannot occur in equilibrium with rock-forming mantle minerals. However, it was suggested that the complex composition of minerals contributes to their stabilization. This paper presents thermodynamic calculations for reactions of diopside–jadeite and pyrope–grossular solid solutions with CO2. It is shown that the formation of the solid solutions expands the stability field of CO2 fluid with eclogite minerals to lower temperatures, corresponding to the geothermal parameters of the continental lithosphere.
