Figure 3
Reinterpretation of the binary MgSeO₄–H₂O phase diagram in light of the measured solubility of the enneahydrate at 269 K (filled square), observations of the incongruent melting behaviour of the undecahydrate and the apparent metastability of the heptahydrate at low temperatures. Open circles are measurements reported by Klein (1940

) and solid lines are assumed to be the equilibrium liquidi and solidi; the dashed lines depict the previously understood low-T behaviour, which we now interpret as being metastable liquidi.
