| 摘 要： | 古断裂是指在变质岩区与谱质岩层变形和南作用同时发生的，在盖层沉积之前形成的断裂，其与断屋有关的断层岩石在后期骏马理新固结成岩。它是前寒武纪变夺内一种重要的构造现象。通过研究，概括总结了古断裂的特点及识别古断裂构造的各种标志，同时探讨了古断理解构造性质。古断裂构造的研究，无乡下对提高前寒武纪地质发展史的认识及对成矿分析和成矿预测具有重要的意义。

| Abstract: | Palaeofractures refer to those fractures occurring in metamorphic terrain which were formed contemporaneously with the deformation and metamorphism of the metamorphic strata but prior to the sedimentation of the covering strata. They are important structural features in the Precambrian metamorphic rocks. This paper summarizes the characteristics and the main identification criteria of palaeofractures, discusses their structural properties, and briefly analyzes the implications in palaeo fracture study. |
