Effects of NaCl concentration on the dihedral angle a Median θ at 800 °C and 1–3 GPa. b θ at 1000 °C and 2 GPa. Blue, orange, and green diamonds represent θ in the olivine–H2O–NaCl systems at pressures of 1, 2, and 3 GPa, respectively. In the pattern-filled area, θ is larger than the critical value of 60°.
