The paper, taking the iso-pressure heat capacity (Cp) for an example of physicochemical properties, has studies the changing regularity of Cp according to temperature and pressure in the crust with the method from National Institute of Standards and Technology (NIST) and showed that the phase transition of water can cause the sharp variations of the physicochemical properties of water and is one of the essential factors to hydrothermal mineralization. From the study, the paper has also revealed the interior coupling relations between the phase transitions of water and fracture or magma activities. At last, the paper suggests that the corresponding relations between fracture epoch and metallogenic epoch can be created by the aid of the water phase transitions and concludes the phase transition of water is the important factor to control the hydrothermal mineralization.
