Abstract: Helanshan complex, situated in the western margin of the North China Craton, consists mainly of khondlite series and deformed granitoids (orthogneisses). The former is composed dominently of sillimanite-garnet gneiss, garnet two-feldspar gneiss, leptineite and a bit of marble and granulite, the later consists mainly of biotite plagioclase gneiss, garnet granite, porphyritic granite and gneissic diorite. By using the zircon SHRIMP U-Pb dating, the authors have been obtained some results for granitoids in this area. The biotite feldspar gneiss and garnet granite formed respectivelly 2053±58Ma and 2047±42Ma, respectively,porphyritic granite and gneissic diorite intruded at 1955Ma and 1920Ma respectively. A lot of geochronology data indicate that a Late-Paleoproterozoic granite zone distributes in the northern margin of the North China Craton. The Late-Paleoproterozoic granitoids formed in three stages, the granitoids of the first stage formed early than 2.0Ga, second stage occurred in 2.0~1.87Ga, the granitoids in third stage intruded at 1.85~1.80Ga. The Late-Paleoproterozoic granitoids in the Helanshan area formed mainly at first and second stage. In the north margin of the North China Craton, Late-Paleoproterozioc granite magmatism accompanied usually by regional metamorphism in time.
