From: Phase diagram and density of SiO2–H2O fluid across critical conditions
Three-dimensional phase diagram of the SiO2–H2O system predicted by the new model. The black solid line represents the hydrous melting curve, and the red point represents the upper critical endpoint. Projected phase boundaries on three planes (T–X, T–P, P–X) are shown with labels marked in the single or coexisting phase regimes. The colored contours are the derived density of saturated fluid under different conditions
