Fig. 3From: Thermodynamic forward modeling of retrogressive hydration reactions induced by geofluid infiltrationThe P–T conditions used in the calculations. For cases I and II, the applied P–T path is from 500 °C and 1.0 GPa to 300 °C and 0.2 GPa. For cases III and IV, the applied P–T 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 P–T diagram was modified after Kuwatani et al. (2011). The colored contours indicate the water contents (weight%) of the globally equilibrated rockBack to article page
