The southern Zhuguangshan complex pluton (SZCP) is one of the important uranium mineralization areas hosted in granitoid in China, and a few granites in SZCP show tungsten mineralization. The Chashan granite in the north central area of the SZCP has received less attention. The LA- ICP- MS zircon U- Pb dating yields an age of 142. 8±1. 9 Ma, suggesting that the Chashan granite was formed in the Early Yanshanian. Petrographically the Chashan granite commonly contains muscovite, and is characterized by enrichment of SiO2, mildly high alkalinity, and depletion of FeOT, MgO, CaO and P2O5. Geochemically it is also highly fractionated (DI=92. 2~95. 6) and peraluminous (ACNK=1. 00~1. 08). Most of samples display low total REE contents (∑REE=90. 5×10-6~163×10-6), negative Eu anomalies (δEu=0. 04~0. 08), enrichment of Rb, U and Ta, and depletion of Ba, Sr, Ti and P. Petrographical and geochemical features of these samples suggest a highly fractionated S- type granite. Isotopically, the Chashan granite has low and constant εNd(t) values (-10. 6~-9. 4) with two stage model age of 1. 70~1. 80 Ga. Integrated with the values of Rb/Sr (12. 6~77. 3) and CaO/Na2O (0. 10~0. 28), we suggest that the granitic magma of the Chashan granite, formed in the Early Yanshanian intraplate extensional environment, may have been derived from the partial melting of metapelite that originated from the ancient crust rocks separated from the mantle in the Paleoproterozoic. An intercomparison shows that the Chashan granite shows similar geochemical properties as the Indosinian uranium- bearing granites and the Yanshanian tungsten- bearing granites in South China, but has extremely low tungsten concentration (1.60×10-6~3.94×10-6), indicating a relatively low tungsten metallogenic potential. These samples exhibit high uranium content (averaging 19×10-6) and common presence of uranium in some U- rich accessory minerals (such as uranothorite) which are prone to be leached. In addition, the faults were well and extensively developed in this area, resulting in the granite being intruded by late stage granitic dykes and experiencing significant hydrothermal alteration. Uranium mineralization found in the northwest part of the Chashan granite and pitchblende was discovered by drilling zk55- 4. In conclusion, the Chashan granite shows a greater uranium than tungsten metallogenic potential.
