The solubility of calcite was studied in the two-phase region calcite + aqueous solution between 200 and 600° C. up to 1,400 bars and to a maximum of 10 weight per cent of CO₂. The results show that the solubility of calcite increases with increasing total pressure. The solubility at constant total pressure decreases with increasing temperature. At constant total pressure and temperature, the solubility passes through a maximum between 4 and 6 weight per cent CO₂.
