测定了方解石、白云石和菱镁矿在CaCl2-MgCl2-CO2水溶液中在275℃~ 420℃之间的稳定性关系。少量的碳酸盐被允许与大量的水溶液平衡，允许从两个方向接近相界。实验数据表明，方解石的稳定性场向高温方向变窄，白云石的稳定性场不一致，菱镁矿的稳定性场扩展到体系的富钙部分。
The stability relations of calcite, dolomite, and magnesite in aqueous CaCl2-MgCl2-CO2 solutions have been determined between 275� and 420�C. Small quantities of the carbonates were allowed to equilibrate with large volumes of aqueous solutions, permitting the approach of phase boundaries from two directions. Experimental data indicate that the stability field of calcite narrows toward higher temperatures, dolomite is incongruently soluble, and magnesite stability extends into the calcium-rich portion of the system.
