摘　　要：描述了矿区剪切蚀变带的构造分布,并揭示了一些韧性变形特征。通过对工作区的韧性剪切带以两种方式进行力学分析。阐述了剪切带的内部具体构造特征以及剪切带的分带性。根据分带性的特征并配合矿区剪切带形态特征对矿区韧性剪切带做了成因研究分析。This paper describes the distribution of structural alteration shear zone in mining area, and revealed some ductile deformation characteristics. Mechanical analysis of the ductile shear zones is done in two ways. It also describes the features of specific structure in the shear zone, and briefly expounds the zonation of the shear zone. The reason for the formation of ductile shear zone in mining areas is analyzed too.
