Abstract: Gaizhou Wanfu-Xiuyan Longtan area is located in the north margin of the North China block, which is on the Mesozoic magmatic arc belt of southeast Liaoning. It is mainly composed of two plutonic rocks. The Heilagou plutonic rocks are fine-grained biotite monzogranite, and the Qianbaogou plutonic rocks are porphyritic biotite monzogranite. The Late Triassic plutonic rocks belong to the calc-alkaline, per aluminous series. The plutonic rocks contain high content of K,Rb,and Sr,low content of Ta,Yb, and Y. The REE distribution pattern is obvious right dipping, with LREE enrichment, HREE depletion, and weak negative Eu anomaly. According to LA-ICP-MS zircon U-Pb dating, the fine-grained biotite monzogranite and porphyritic biotite monzogranite were formed in the Late Triassic ((219.8±0.7) Ma and (220.9±2.1) Ma). Based on the analyses of petrology, petro-chemistry, chronology, and tectonic environment, combined with the study of the tectonic evolution in the adjacent area, it is considered that the intrusive rocks are syncollisional S type granites, which were produced by the thickening and remelting of the silicon aluminum layer in the crust during the collision between the Yangtze plate and the North China craton.

Key words: Late Triassic, monzogranite, zircon U-Pb dating, geochemistry, southern Liaoning Province
