摘要
本文着重对产铀花岗岩区断层岩类型、显微构造特征以及断层岩与铀矿化的关系作了简要论述。断层岩往往直接控制铀矿体的展布。矿石的贫富、矿化类型的差异常常取决于断层岩本身的特点。找矿勘探实践表明,不少成矿断层岩本身就是矿石。根据断层岩受力性质,破碎程度及显微构造特征等综合因素分析,笔者将产铀花岗岩区断层岩划分了5大类16亚类,强调了碎裂岩类和构造角砾岩类断层岩对铀矿化的控制作用。
This paper briefly discusses the types of fault rocks, microstructural characteristics of fault tectonite and their relationship with uranium mineralization in the uranium-productive granite area. According to the synthetic analysis on nature of stress, extent of crack and microstructural characteristics of fault rocks, they can be classified into five groups and sixteen subgroups. The author especially emphasizes the control of cataclasite group and fault breccia group over uranium mineralization in the uranium-productive granite area. It is considered that more effective study should be made on the macrostructure and mi- crostructure of fault rocks. It is of an important practical significance in uranium ex- ploration.
