摘　　要：研究区位于华南板块的东南缘,含铀花岗质岩体广泛出露,为该区域铀矿化的富集提供了成矿地质条件。研究区矿体受岩体和断层双重控制,目前已发现44个铀矿体,主要分布于近南北向F_(5)断裂和F_(5)-1断裂、北北西向F_(17)断裂、北东向F_(2)断裂和北西西向F_(4)断裂。区内铀矿化的富集经历了高中温、中低温、低温三个时期以及花岗岩自交代作用、花岗岩碱交代作用、高中温热液蚀变作用、中低温热液蚀变作用、低温热液蚀变作用五种类型。根据区内铀矿成矿规律,花岗岩体、断裂构造、矿化蚀变、矿物组合是该区域铀矿体的主要找矿标志。The study area is located at the southeastern margin of South China Plate,where uranium-bearing granitic rock mass is widely exposed,which provides metallogenic geological conditions for the enrichment of uranium mineralization in this area.The ore bodies in the study area are controlled by both rock mass and faults.Currently,44 uranium ore bodies have been discovered,which are mainly distributed in SN oriented F_(5)fault and F_(5)-1 fault,NNW oriented F_(17) fault,NE oriented F_(2) fault and NNW oriented F_(4) fault.The enrichment of uranium mineralization in the area has experienced three periods of hightemperature,medium-low-temperature and low-temperature,as well as five types of granite autometasomatism,granite alkali metasomatism,high-temperature hydrothermal alteration,medium-low-temperature hydrothermal alteration and lowtemperature hydrothermal alteration.According to the regularity of uranium mineralization in the area,granite mass,fracture structures,mineralization alteration and mineral association are the main prospecting signs of uranium bodies in the area.
