The Gibbs free energy of the mixing surface for the MgSiO3–H2 system at 3591 K and 4 GPa as formulated by L. Stixrude & T. Gilmore (2025). The binodes for the melt and envelope phases at this T and P, as well as the tie line between them, are shown for clarity. Also shown are the positions of the spinodes where the curvature is zero.
