From: Water-carbon dioxide solid phase equilibria at pressures above 4 GPa

Temperature-composition phase diagrams at 4 and 6 GPa. In the current experiments, temperatures and pressures were measured, however composition values are unknown for most of the diagram, and boundaries indicated by dashed lines are approximate. The two eutectic points (A and C), the peritectic point (B) and the melting point (D) correspond to the similarly designated curves in Fig. 2.
