The solubility of calcite in distilled water has been measured at 75°, 100°, 125°, 150° and 200°C at CO 2 pressures between 2 and 60 atm. Samples of solution in equilibrium with calcite and a vapor phase were taken at the operating temperature and pressure; their calcium content was determined by means of an EDTA titration. Our results agree quite well with those of Ellis and are consistently higher above 10 atm than those of Miller. The experimentally determined solubility isotherms can be fitted adequately with curves calculated on the basis of Debye-Hückel theory, and the observed decrease of calcite solubility with increasing temperature agrees quantitatively with that expected on the basis of available thermodynamic data. Our results indicate that hydrothermal solutions should tend to become undersaturated with respect to calcite on cooling. Calcite precipitation is therefore probably due to causes other than simple cooling. Loss of a vapour phase is one possible mechanism of calcite precipitation which may be of importance in certain epi- and meso-thermal deposits, but it does not seem to account for calcite precipitation in the majority of ore deposits.
