Experimental determination of the reaction aragonite + magnesite = dolomite at 5 to 9 GPa

Martinez et al. bracketed the decomposition reaction of dolomite to aragonite + magnesite between 5.0 and 5.5 GPa at 600 degreesC using in-situ XRD in a multianvil apparatus. They then extrapolated their results using the available thermodynamic data such that the breakdown reaction occurs at ~1,000...

Description
Summary:Martinez et al. bracketed the decomposition reaction of dolomite to aragonite + magnesite between 5.0 and 5.5 GPa at 600 degreesC using in-situ XRD in a multianvil apparatus. They then extrapolated their results using the available thermodynamic data such that the breakdown reaction occurs at ~1,000 degreesC at 6 GPa.
