| 摘 要： | 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。

| Abstract: | Based on the study on the ultrahigh-pressure metamorphism and the calculation of pressure pervading in the crust,the present paper shows that the pressure causing ultrahigh-pressure metamorphism should include in addition to the load of surrounding rocks also the pressure arising from phase change,and tectonism. A model for ultrahigh-pressure metamorphism to is thus proposed. In this model the pressure-depth relation is not linear. |
