该文在研究地球内部压力的计算过程和超高压变质作用过程的基础上 ,指出超高压变质作用的压力不仅包括静岩载荷压力 ,还应包括构造超压和体系内部的相变增压 ,并给出了超高压变质岩区的初步压力模型 ,得出了超高压变质作用中压力与深度是非线性关系的认识。 Based on the study of the calculation of the pressure inside the earth and the process of UHP metamorphism, the paper points out that the pressure of UHP metamorphism includes not only the load of static rock, but also the overpressure of structure and the phase transition pressure inside the system The preliminary pressure model of the UHP metamorphic rock area is given, and the understanding of the nonlinear relationship between pressure and depth in the UHP metamorphism is obtained.
