A detailed discussion is made on the calculation of the thermodynamic parameters through the element partition reaction by the method of least squares curve fitting. Systematic calculation of adjusted parameters is also given on the statistically sound basis. The thermodynamic properties of olivine, orthopyroxene and clinopyroxene are calculated by the proposed least squares method for the existing data. Results of the previous and new treatments on the orthopyroxene-clinopyroxene pair are compared in Fig. 1 as an example.
