Zhangjiafen group of Miyun is a set of Archean highgrade Metamorphic rock.The field feature of Zhangjiafen group was studied. The rock is mylonite. Amounts of special structuressheth fold and knee fold were developed in addition to foliation and lineation. Analysis results showed that microdeformation mechanism was mainly misplace,dislocation creep and superductile flow.Metamorphism and strain analysis suggested that the area deformation controlled the formation and evolution of metamorphic differentiation. Deformation of shear zones was characterized by the shear and flaser. The above study pointed out that Miyun Zhangjiafen group was tonalite complex reformed by polyductile shear deformation,without strata meaning. It is a typical ductile shear zone.
