Abstract: Precambrian basement is distributed nearly east-west trending in the Damaoqi area along the northern margin of the North China Craton.Previous studies classified it as the Sertengshan Group based on the characteristics of rock assemblage, but without chronological evidence.This paper discusses the Precambrian basement rock assemblage, formation age and material source in this area, based on petrology, LA-ICP-MS zircon U-Pb age and trace element geochemistry, and zircon Lu-Hf isotope.The research shows that the Precambrian basement is composed of the Sertengshan Group and Paleoproterozoic metamorphic intrusions.The Sertengshan Group is composed of biotite plagiogneiss and marble, formed during 2009~2142 Ma and belongs to the Paleoproterozoic.There are two periods of intrusions in Paleoproterozoic, 1992~1999 Ma and 1920 Ma respectively.In the Damaoqi area, continental crust accretion occurred at ~2.6 Ga and 2009~2142 Ma, respectively.The alkali feldspar granite and quartz diorite formed at 1999~1992 Ma were remelted products of juvenile continental crust, which may be contaminated by ancient continental crust materials.The biotite monzogranite formed at 1920 Ma was the product of the remelting of the ancient continental crust.The results of this study provide more evidences for the Precambrian tectonic evolution of the northern margin of the North China Craton.
