摘　　要：皖南地区发育多条北东向大型韧性剪切带,其发育在不同地质体的边界。本文利用天井山、小贺、白石坑、田子坑、韩家、大片等6条重要实测构造地质剖面,和大量室内显微构造的专题研究,从构造几何学、构造岩石学、构造运动学等方面进行了璜茅–五城–屯溪韧性剪切带的精确厘定。阐述了韧性剪切带的延伸方向、规模、剪切变形特征、变形条件及形成的变质相。There are many large size ductile shear zones of northeastern run in southern Anhui province. And they were developed in the boundary of different geological bodies. This paper uses the Tianjingshan section, Xiaohe section, Baishikeng section, Tianzikeng section, Hanjia section and Dapian section that 6 geological sections and a large number of microstructures research to precise determination the Huangmao-Wucheng-Tunxi ductile shear zone from the structural geometry and structural petrology, structural kinematics etc. And we described the ductile shear zone about the extension direction, scale, shear deformation characteristics, deformation condition and the metamorphic facies.
