There are a large number of Mesozoic intrusive and volcanic rocks in western Liaoning of China, which is an ideal place to study the Mesozoic Paleo-Paci?c subduction processes, and lithospheric destruction of North China Craton. Detailed petrographic, zircon U-Pb dating and geochemical studies of the Early Jurassic granites in Huashan pluton, Xingcheng, western Liaoning, indicate that the Early Jurassic granites were formed at 184–174 Ma, mainly composed of syenite and monzogranite. The geochemical characteristics show high contents of SiO2, Al2O3 and Na2O+K2O, low contents of Fe2O3 and MgO, enrichment in LREEs and LILEs, and depletion in HREEs and HFSEs, and have a high content of Sr and low contents of Y and Yb, with weak negative Eu anomalies and slightly negative anomalies of Ce, indicating that they are a set of intermediate-acidic adakitic granites in high-K calc-alkaline series. All the facts signi?cantly suggest that the Early Jurassic adakitic granites were formed at the active continental margin in the context of Paleo-Paci?c plate subduction.
