This paper reports LA-ICP-MS zircon U-Pb dating, geochemical and Sr-Nd-Pb isotopic data of the granite from Wolongquan intrusion in Liaodong Peninsula, with the aim of constraining its petrogenesis and its geodynamics. The Wolongquan intrusion consists mainly of biotite adamellite. The LA-ICP-MS U-Pb dating results of zircons from the biotite adamellite indicate that the intrusion formed in the Early Jurassic (194.0±1.0Ma, MSWD=1.3). Geochemically, these rocks fall into the high-K calc-alkaline series, with an A/CNK ratio of 1.07～1.10, which are peraluminous granites, being of the characteristics of I type granite, enrichment in LILE（such as K, Rb）, LREE, relatively depleting in HFSE（such as Nb、Ta、P、Ti）. The（87Sr/86Sr）i values of the biotite adamellite vary from 0.71572 to 0.71660, and εNd（t）from -15.6to -17.6, corrected 206Pb/204Pb(t) ranges from17.842 to18.052，207Pb/204Pb(t) ranges from 15.542 to 15.557, 208Pb/204Pb(t) ranges from 38.797 to 39.917. Sr-Nd-Pb isotopic characteristics combine with geochemistry of biotite adamellite indicate that it was the result of partial melting of thickened crust. Based on former and present study, we conclude the biotite adamellite from Wolongquan intrusion and the Jurassic magmatism in the eastern North China Craton formed in a continental crustal thickening setting that may be related to subduction of the Paleo-Pacific oceanic plate, which induced paitial melting of lower crustal materials of the North China Craton．
