Study of the phase equilibrium of minerals has been one of the major field in Mineralogy. Various studies on phase relations of minerals have been conducted to date under the controlled conditions of pressure, temperature, and oxygen fugacity. The knowledge of the phase equilibrium and phase relations provides important clues to estimate the formation conditions of the minerals. 14 papers, which can estimate various environments including the Earth's surface and its deep interior, and those of the extraterrestrial and early solar system, are presented in this session.
