The high pressure and high temperature technology has rapidly developed. Today the imitable temperature and pressure condition has attained nearly or up to the core. The techniques of high pressure and synchrotron radiation applicated in geosciences. It can obtained pressure region of 14GPa-100GPa and temperature of 1700℃-1000℃.Many results of application of synchrotron radiation to high pressure research have been obtained. The success of a phase equilibrium investigation under high pressure and high temperature promote development of high pressure mineralogy and mineralogical physics, new specific'properties of mineralogical materials and information are considered. Metamorphism under extremly condition is a new area of experimental investigation under mantle pressure of minerals and rocks, it is a important channel to link the crust activity and the earth deep interior.
