The present reseaching of forward modeling of orogenic metamorphism has been restrained by the thought that metamorphic grade is function of depth. Its assumption didn't reflected the insitric characteristics of orogenic metamorphism. The data from the reversing approaches indicates that the uneven gushing of thermal and structural flow in orogenic belt results in progressive metamorphism, granitization and progressive deformation and development of thermal-structural-gneiss dome.
    It is important developing trend to combine temporal evolution and three-dimentional spatial variation of progressive metamorphism, granitization and progressive deformation and construct a unified geodynamic system between orogenic metamorphism and the process of lithosphere movement under the orogenic belt.
