///Early Precambrian bandedi （NCC）, such as northern L Daqingshan, Wutai, Luliang, Abundant SHRIMP U-Pb data from Paleoarchron formations （BIFs） are widely Liaoning, Anshan-Benxi, western distributed in the North China Craton, Liaoning Province, eastern Hebei Province, Guyang, Defeng, Zanhuang, Huoqiou, western Shandong Province, eastern Shandong Province. The results indicate that BIFs in the NCC show large variations to Early Paleoproterozoic, but mainly concentrate in Late Neoarhcean （2.55～2.50 Ga）. It may suggest that stable environment should be necessary in formation of hugescale BIFs. The Late Neoarchean BIFs are considered to be formed in mantle plume or more possibly, arcisland environment. The age distribution of BIFs is mainly due to geological and atmosphere evolution throughout Earth history.
