The Zhangbaling metamorphic belt and the Fucha Shan metamorphic zone are metamorphic terranes that occur along the Tan-Lu fault, the major strike-slip fault that separates the ultra-high-pressure metamorphic belts of Dabie Shan and Sulu in SE China. The greenschist-facies Zhangbaling metamorphic belt is characterized by subhorizontal foliation, belt-parallel lineation, and a top-to-south sense of shear; ⁴⁰Ar/³⁹Ar analysis of synkinematic white mica dates deformation at ca. 235–240 Ma, coeval with reported peak metamorphic ages of ultra-high-pressure metamorphism in Dabie Shan. The Fucha Shan metamorphic zone is composed of felsic to mafic mylonite and is characterized by subvertical foliation...
