Taoshan-Zhuguang uranium metallogenic belt, an important granite-type uranium metallogenic belt in China, mainly conclude Taoshan, southern Zhuguangshan and Guidong complexes which produce uranium. In this paper, geochronological data of granite, mafic veins and uranium mineralization in recent years within this belt were collected. In addition, research progress about the geochronology of diagenesis and mineralization within this belt were summarized and main existing problems were analyzed. Statistical results show that the high-precision chronological data in recent years have improved the accuracy of chronology to a certain extent and promoted our understanding of the relationship between granite, mafic veins and uranium mineralization. However, geochronological data within this belt mainly have the problems in the following: (1) there are some problems about zircon U-Pb dating results in granite, such as lack of data, high NSWD and undeleted high uranium data, which cannot provide a basis for the determination of the time series of the complex massif. (2) Ar-Ar method (susceptible to late alteration or thermal time) and the high-precision U-Pb method (difficult to crystalize a large number of zircons from the mafic magma) are commonly used in the mafic veins. (3) Testing methods to uranium metallogenic ages are susceptible to the detecting limit, standard samples and high uranium effects. In summary, although high-precision geochronology in recent years has deepened our understanding of uranium formation in recent, the testing methods and data processing of geochronology still need to be solved.
