英文摘要	We present zircon U-Pb ages, Hf isotopes, and whole-rock geochemistry of the Xiaochuan gneissic granite intrusion, SE China, to constrain its petrogenesis and provide insights into early crustal evolution of the Cathaysia Block. LA-ICP-MS zircon U-Pb dating of a representative sample yields a weighted mean Pb-206/Pb-207 age of 1839 +/- 16Ma, interpreted as the emplacement age of the Xiaochuan granite. Zircons have E-Hf(t) values ranging from -8.1 to 2.7 and T-DM2 model ages from 2.23 to 3.03Ga. The granites are strongly peraluminious (A/CNK=1.14-1.41), with relatively high FeOt, TiO2, and CaO/Na2O, and low CaO, Al2O3/TiO2, and Rb/Sr values. In addition, they show strongly negative Ba, Sr, Nb, and Ta and positive Th and Pb anomalies in the primitive mantle-normalized spider diagram, similar to other Cathaysia Palaeoproterozoic S-type granites. The geochemical and Hf isotopic signatures suggest that the Xiaochuan gneissic granites were generated by partial melting of Archaean crustal materials in an intraplate extensional setting. Our results, combined with existing geochronological data, further demonstrate that the Wuyishan terrane is underlain by Palaeoproterozoic crystalline basement.
