This study utilizes ANSYS to establish FEM’s model of metamorphic core complex,and used thermal-structure analysis to simulate metamorphic core complex’s temperature field and stress field.The metamorphic core complex formation mechanism is discussed.The simulation results show that the temperature field change appearing as the earth surface’s temperature is the lowest,and the temperature of metamorphic core complex’s nucleus is the highest.The temperature field is higher along with depth increase,and the stress field change appearing as the biggest stress occurs in the nucleus.The next stress field occurs at the top of the cover.
