Temperature and pressure dependence of dihedral angles. a–c Temperature dependence. d–f Pressure dependence. The blue circles and orange triangles represent the data in the H2O and H2O–NaCl (27.5 wt% NaCl) systems, respectively. In the pattern-filled area, θ is larger than the critical value of 60°, and the intergranular fluid is thus isolated in the fluid pockets; the fluid is interconnected when θ is <60°.
