The continental collision orogens are formed by the high coupling and spatio—temporal evolvement of the selforganizing system —— deformation, metamorphism and anatexis. Those three geologic processes are trinity. Therefore, it is significant to understand the dynamics of the collision orogens from this study. In this study, we summarized the research progress of deformation, metamorphism and anatexis in the continental collision orogens. Meanwhile, we review the research status and existing problems of deformation, metamorphism and anatexis in eastern Himalayan syntaxis, we also discussed and prospected the future research direction of this area.
