摘要
Zhangpu complex is a large Yanshanian periods complex. By LA-ICPMS U-Pb chronological study of zircons, it is believed that the metamorphic granodiorite of Baikeng intrusive, which was divided into early Jurassic periods, is dated at 149.9 Ma using the LA-ICPMS zircon U-Pb method and represents product of the Early-Late Jurassic magmatism, and the metamorphic Gumeishan sequence belong to the late-late Jurassic periods, and the metamorphic Zhangpu sequence belong to Early Cretaceous. Zhangpu sequence is the product of the Early Cretaceous magmatism which forms Zhangzhou sequence, is deformated and metamorphic in the Changle-Nan’ao fault zone.
