Located in the northeast of Jiangxi Province along the Qinzhou-Hangzhou junction belt, the Yaoli granite intruded into the Shuangqiaoshan rock group and Xikou rock group. The granite is mainly composed of quartz, potash feldspar, plagioclase, biotite and minor muscovite. The LA-ICP-MS zircon U-Pb dating shows that the one-forming age of the Yaoli pluton is 132.0±1.9 Ma, with another age of 141.7±2.6 Ma, suggesting that another magmatic activity occurred at 141.7±2.6 Ma. The Yaoli pluton is characterized by high K₂O/Na₂O ratios and SiO₂ content as well as low content of Al₂O₃, MgO, CaO and TiO₂. The A/CNK ratios vary from 0.92 to 1.17, mostly higher than 1.1, implying that the Yaoli granite belongs to high-K calc-alkaline and peraluminous series.The Yaoli granite is also enriched in LILEs but depleted in HFSEs of Nb and Ti.The δEu values vary from 0.30 to 0.86. The granite is remarkably characterized by enrichment of LREE, which is similar to things of Ehu pluton and Wolonggu pluton which were formed at the same time as the Yaoli granite.They were all generated by partial melting of metamorphosed argillaceous rock in the deep crust;nevertheless,the Yaoli granite is different from Tongchang granite,which formed in Middle Jurassic.These data show the decrease of formation temperature and pressure of the granite from Middle Jurassic to Early Cretaceous, suggesting that the tectonic setting of the northeast of Jiangxi Province along the Qinzhou-Hangzhou junction belt was an extensional tectonic environment.
