英文摘要	SHRIMP zircon U-Pb dating in the Liguo and Jiagou intrusives indicates that they were formed at similar to130 Ma in the Early Cretaceous. Most inherited zircons in the Liguo intrusive were formed at 2509 43 Ma. Most inherited and detrital zircons in the Jiagou intrusive were formed at similar to2500 Ma, similar to2000 Ma and similar to1800 Ma. The SHRIMP zircon U-Pb dating in two gneiss xenoliths from the Jiagou intrusive yields the ages of 2461 +/- 22 Ma and 2508 +/- 15 Ma, respectively. The dating results from inherited and detrital zircons in the intrusives and the gneiss xenoliths imply that the magmas could be derived from the partial melting of the basement of the North China Block (NCB). The magmatism is strong and extensive in the periods from 115 to 132 Ma, which is of typical bimodal characteristics. It is suggested that the lithospheric thinning in the eastern North China Block reached its peak in 115-132 Ma.
