Hello. I've a question two question about the uses of solid solution function with PHEEQCI. -first question: it's possible to calculate a saturation index as regards to a solid solution? For example, if I've a water composition with Fe, Mg, SiO2, can I calculate the S.I. for: SOLID_SOLUTIONS 1 olivina Mg(X)Fe(1-X)SiO4 -comp Forsterite 0.9 -comp Fayalite 0.1 or only for the pure phase? -second question: it's possible to use the solid solution assemblage in the REACTION function formula with other pure phase mineral. For example (hypothetical input file): REACTION 1 Enstatite 1 Hedenbergite 1 SOLID_SOLUTIONS 1 olivina Mg(X)Fe(1-X)SiO4 -comp Forsterite 0.9 -comp Fayalite 0.1 1 moles in 25 steps Thank you. Best Regards.
