ChongYuYou mineral deposit intensive area is renowned for its wolframite. This paper focuses on the study of 40Ar/39Ar chronology of muscovite from three deposits: Keshuling and Piaotang tungstentinmultiple metals deposits (sulphide quartz vein type), and Xian'etang tungstentin deposit (quartz vein type) in the ChongyiDayuShangyou concentrated mineral area. The 40Ar/39Ar plateau age is 158.8±1.9 Ma, that of Keshuling is 158.8±1.2 Ma for Piaotang, and 231.4±2.4 Ma for Xian'etang, and the 40Ar/39Ar reverse isochron ages are 158.9±1.4 Ma, 158.7±1.9 Ma, and 232.5±2.4 Ma respectively. These results indicate that there occurred two metallogenic epochs in the ChongYuYou intensive mineral area. Namely, the tungstenmultiple sulfide quartz vein type deposits formed in the Middle Jurassic Epoch mainly between 160 and 150 Ma, similar to the major metallogenic epoch of tungstentin deposits in the Nanling region; the cassiteritescheelite quartz vein type deposits formed in the IndoChinese Epoch. The authors also discussed the granite diagenesis and mineralization in the IndoChinese Epoch and the inherited features of the Mesozoic mineralization in the Nanling area.
