水的相变:热液成矿作用的重要控制因素之一
The Phase Transition of Water:One of the Important Factors Controlling the Hydrothermal Mineralization
摘要
Abstract
Water is the main composition of the geo-fluid in the hydrothermal mineralization. The phase transition of water is also the key factor to understand the processes of hydrothermal mineralization, as well as the reactions among various substances and the geological evolutions. The paper, takes the iso-pressure heat capacity (C_p) for example of physicochemical properties, has studies the changing regularity of C_p 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. Furthermore, the article 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.关键词
