The effect of total solution concentration on the Ca: Mg ratio at the magnesitedolomite and the dolomite-calcite boundaries in CaCl2MgCl2CO2 solutions has been determined between 280 and 420°C. Below about 410° a decrease in the total concentration of the solutions produces a displacement of both boundaries toward lower values of the Ca:Mg ratio. Observed displacements are small but increase with decreasing temperature.
