摘　　要：本文研究了典型韧性变形断裂和弱变形区的岩石磁组构特征。结果表明，磁组构能确定断裂运动方向、构造变形性质、变形历史及反映变形与成矿的关系；在韧性剪切带控矿区，金矿化与变形强度呈正比；弱变形区断裂控矿的枞树板铅锌矿区，变形强度与成矿成反比。The paper studies magnetic fabric characteristic of faults developed in the typical ductility and weak deformation areas. The results show that the magnetic fabric can be used to determine the movement orientation of faults,structural deformation feature and deformation history. The magnetic fabric also reflects the correlation between fault deformation and metallogeny: gold mineralization and deformation intensity is positive correlation in ductile fault zone and negative correlation in Congshuban Pb-Zn area with weak deformation.
