Abstract: Zircons and rocks older than 3.4Ga have been discovered in many areas of Chinese continent. Anshan City is one of a few areas in the world where ≥3.8Ga continental rocks have been identified. They occur in volumetrically small amounts in the Baijiafen, Dongshan and Shengousi complexes and consist of mylonitized trondhjemite,banded trondhjemite and meta-quartz diorite. Many 3.7~3.6Ga rocks and zircons have also been found recently in the Anshan area. The Hf isotopes of the zircons indicate that Anshan mantle addition and continental formation happened episodically from 3.8 to 3.6Ga. Besides Anshan, ≥3.4Ga ages of zircons from different kinds of rocks in many areas of China have also been obtained, although most of them are detrital and inherited in origin. (1) 3.85~3.55Ga detrital zircons from Archaean fuchsite quartzite in eastern Hebei, North China Craton (NCC); (2) 3.66Ga magmatic zircons from felsic granulite xenoliths in Mesozoic volcanic rocks in Xinyang, NCC; (3) 3.80Ga detrital zircon (one grain) from Neoproterozoic sandstone in Yichang of the Yangtze Block, South China Craton (SCC); (4) 3.76~3.6Ga detrital zircons from Neoproterozoic-Palaeozoic meta-sedimentary rocks in the Cathaysia Block, SCC; (5) 3.6Ga inherited zircons from a Palaeoproterozoic gneissic granite in the Aketashtage area, Tarim Block, Northwest of China. (6) A grain of 4.08Ga old zircon captured by an Ordovician meta-volcanic rock in Zhangjiazhuang, West of northern Qinling orogen; (7) One 4.1Ga detrital zircon (with 3.61Ga rim) from an Ordovician quartzite in Pulan, Tibet. Some of the ancient zircons have Hf isotope model ages as old as 4.1~4.0Ga. The proportion of >3.4Ga crustal materials in China has been underestimated and there are new possibilities for finding Hadean and Eoarchean materials to constrain early terrestrial evolution.
