Resumen: Different thermodynamic databases usually have common thermodynamic data for some minerals or aqueous species, but in many cases they present important differences. Four different thermodynamic databases (WATEQ4F, LLNL, DATA0.YMP.R5 and SOLTHERM) have been used in a geothermometrical modelling problem and they are compared in this work. The main differences found in the thermodynamic data are related to the order, degree, crystallinity and composition of the considered aluminosilicate phases and the effects of these properties in the experimental, or theoretical, data used for the fitting of the equilibrium constant at different temperatures.
