Early Precambrian banded iron formations (BIFs) are widely distributed in the North China Craton (NCC), such as northern Liaoning, Anshan-Benxi, western Liaoning, eastern Hebei, Guyang, Daqingshan, Wutai, Luliang, Defeng, Zanhuang, Huoqiou, western Shandong, eastern Shandong. Abundant SHRIMP U-Pb data obtained in recent years indicate that BIFs in the NCC show large variations in formation age from Paleoarchean to early Paleoproterozoic, but mainly concentrate in late Neoarhcean (2.55~2.50 Ga). The most important BIFs occur in Anshan-Benxi, eastern Hebei and western Shandong in the eastern NCC where earlier (2.6 Ga) continental basement had been developed. This may suggest that stable environment should be necessary in formation of huge-scale BIFs. The late Neoarchean BIFs are considered to be formed in mantle plume or more possibly, arc-island environment. The age distribution of BIFs is mainly due to geological and atmosphere evolution throughout Earth history.
