Abstract

It is proposed to model magnesian calcites thermodynamically as dilute solid solutions of MgCO3 in CaCO3 according to the Unified Interaction Parameter Formalism (Bale and Pelton, Met. Trans. A21A, 1997–2002, 1990). In this case both stoichiometric saturation and precipitation data of synthetic magnesian calcites taken from literature can consistently be explained.
