The PT conditions used in the calculations. For cases I and II, the applied PT path is from 500 °C and 1.0 GPa to 300 °C and 0.2 GPa. For cases III and IV, the applied PT condition is 300 °C and 0.2 GPa. The equilibrated condition of the original rocks was set to 500 °C and 1.0 GPa for case III and 400 °C and 0.8 GPa for case IV. The PT diagram was modified after Kuwatani et al. (2011). The colored contours indicate the water contents (weight%) of the globally equilibrated rock
