Solubility Measurements in the System CaSO4–NaCl–H2O at 35°, 50°, and 70°Cand one atmosphere Pressure

The solubilities in the system CaSO4–NaCl–H2O, at 1 atm pressure and 35°, 50°, and 70°C, have been determined by approaching the solubility curves from both the undersaturation and supersaturation sides. The experimental runs are of long duration, as much as 3 months; these rates should be commensurate with those of the appropriate geological processes, and so the results should be directly applicable to the interpretation of evaporite deposits.
