Abstract: The Sertengshan Group is an important component of the Early Precambrian metamorphic basement in the mid-west of the North China craton. It is of significance to study the tectonic evolution of the Early Precambrian North China craton. The formation age of the Sertengshan Group is one of the current research hotspots. In this paper, through the study of petrology and zircon SHRIMP U-Pb dating, the rock composition and chronological characteristics of Dongwufenzi Formation of the Sertengshan Group in the Chaganhada area of Urad Zhongqi were identified. The Dongwufenzi Formation suffered severe destruction of magmatism and tectonism in the later period, and has no an intact top and bottom. It is mainly composed of medium-fine amphibolites, fine-grained biotite plagioclase gneisses, augen fine-grained biotite plagioclase gneisses, banded fine-grained biotite plagioclase gneisses, and fine-grained biotite hornblende schists. The mineral assemblage characteristics indicate that it experienced low green schist facies-low amphibolite facies metamorphism. Most automorphic and semi-automorphic zircons with oscillatory zoning indicate its magmatic origin from the fine-bearing biotite plagioclase gneiss. The zircon SHRIMP U-Pb dating results (1 930.7±9.6 Ma) represent the formation age of basal rock, suggesting that the metamorphic age of the Dongwufenzi Formation should be later than 1 930 Ma.

Key words: biotite plagioclase gneiss, granitic gneiss, zircon U-Pb age, Sertengshan Group, Dongwufenzi Formation, Urad Zhongqi
