Calcite-Dolomite-Magnesite Stability Relations in Solutions at Elevated Temperatures
Abstract:
The stability relations of calcite, dolomite, and magnesite in aqueous CaCl(2)-MgCl(2)-CO(2) solutions have been determined between 275 degrees and 420 degrees 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.
