The Guangzitian deposit is a typical Carbon—Silicon-Shale type uranium deposit in northern Guangxi, with the unique attribute of uranium—tungsten symbiosis, but the previous studies on the deposit are relatively low, and there is a lack of necessary constraints on the mineralization and metallogenic age of the deposit.Methods: In this paper, the electron probe method analysis (EPMA) was carried out to analyze the composition of scheelite and pitchblende, and the LA-ICP-MS method was used to analyze the U-Pb isotope and rare earth element content of pitchblende.Results: The results of electron probe and LA-ICP-MS elemental analysis show that pitchblende is characterized by higher UO2, CaO and WO3 contents and lower SiO2 and ThO2 contents, as well as higher LREE/HREE ratio, moderate negative δCe anomaly and δEu anomaly, while scheelite has higher MoO3 content. In-situ LA-ICP-MS U-Pb dating of pitchblende yielded a lower intercept age of 30. 8±4. 2 Ma (MSWD=0. 13), and the initial common lead \[n(207Pb)/ n(206Pb)\]0 of pitchblende is 0. 22, which is belongs to abnormal lead.Conclusions: The metallogenic age of Guangzitian deposit is 30. 8 ±4. 2 Ma, corresponding to the late regional metallogenic event of about 25 Ma in South China. The ore-forming fluid is medium—low temperature and medium—low salinity oxidizing fluid rich in U and W elements, and the tungsten deposit formed in the early stage may provide some ore-forming materials for the formation of Guangzitian deposit.
