断层岩与铀矿化

FAULT ROCKS AND URANIUM MINERALIZATION

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.
