From: Phase diagram and density of SiO2–H2O fluid across critical conditions
Solubility of SiO2 in the fluid predicted by the new model as a function of temperature and pressure. The red line represents the critical curve, the thick black line represents the hydrous melting curve; the thin black lines are the isopleths of SiO2 solubility under SLE; the black dashed and gray solid lines represent the isopleths of SiO2 solubility in aqueous fluids and hydrous silicate melts under VLE, respectively
