From: Phase diagram and density of SiO2–H2O fluid across critical conditions
Comparison of the density, volume and solubility of quartz-saturated SiO2–H2O fluids predicted by the two-step model and the HM2012 model. a At isothermal and b isobaric the density of quartz-saturated fluids predicted by the two models; c solubility and d volume of quartz-saturated fluids under isothermal conditions predicted by the two models (solid and dashed lines represent the two-step model and the HM2012 model, respectively, and the lighter solid line in (b) represents the density of the coexisting VLE fluid)
