=EN-US>///It is shown that regular patterns can be established for the distribution of BIF-iron deposits in the North China Craton (lang=EN-US>NCC)lang=EN-US>. Large scale BIF-iron deposits mainly exist in some greenstone-belts areas such as Anshan-Benxi, eastern Hebei, Huoqiu-Wuyang, Wutai, western Shandong and Guyang etc; formation ages of BIF in the NCC cover a wide range from Paleoarchean to Early Paleoproterozoic, among which Late Neoarchean is the peak period (lang=EN-US>2.52~lang=EN-US>2.56 Ga)lang=EN-US>MingLiU>.lang=EN-US>BIF can be divided into two types, Algoma and Superior Lake. This paper argues that comprehensive discriminant should take the greenstone belt development sequences into consideration when discussing the types of BIF iron deposits. Large amount of geochemistry research results of BIFs in the NCC indicate that BIF iron ores lack Ce negative anomaly and their iron isotope characteristics are positive, which suggest that iron deposits formed in low-oxygen or anoxia environments, and the Eu positive anomaly may indicate that BIFs are hot water deposits. lang=EN-US>lang=EN-US>
