Abstract:The Furong pluton, located in central Hunan, China, hosts numerous tungsten veins within and around the granite, which are of great economic significance. However, its petrogenesis and related mineralization are poorly constrained. In this study, we used U-Pb dating, petrological and geochemical methods to ascertain the emplacement time, classification of granitic rock, nature of the source rocks, formation mechanism, and its geodynamic implications for the Furong pluton. It is shown that the granite is precisely determined to be formed at ~210 Ma, and belongs to the moderately-fractionated S-type granite. Combined with regional tectonic setting, it is concluded that the pluton was formed due to crust extension and thinning followed by plate collision and compression in South China. It is also revealed that tungsten mineralization and Indosinian granites exhibit a close temporal, spatial and genetic relationships, and further exploration of tungsten deposits within and around the granite in central Hunan, even in South China, is urgently needed.
