Based on the field geological survey, lithography and thermodynamics evaluation, and p-t condition change of peak metamorphism in the Susong metamorphic complex (SSC), this study discussed the lithological compositions and metamorphic features of the Susong metamorphic complex (SSC). The results indicate that the Susong complex can be divided into three zones from north to south, with epidote-amphibolite to amphibolite facies as the main metamorphism. The temperature and pressure ranged from398 to 613℃ and 0.61~1.53 GPa, respectively, with average p-t conditions of 517℃ +50℃ and 1.03+0.21 GPa. But the metamorphic complex does not show any characteristics of glaucophane facies and temperature zonation or gradual temperature trend within the complex.
