Calibration curve for SiO2 solubility as a function of 770 + 850 cm−1 integrated band intensity from the system –H2O with silica solubility calculated with the algorithm of Manning (1994). The fitted curve is log mSiO2 (kg/mol) = 1.6–2.0 × Int−0.32, where “Int” denotes the integrated Raman intensity and mSiO2 is silica molality of aqueous fluid
