In this paper, petrology and petrochemistry of Hanwang BIF were studied and a comparison was made with other BIF in the world. Petrological studies show that the BIF suffered greenschist facies to low amphibolite facies metamorphism and part of the magnetite was recrystallized whereas the other part of the magnetite preserved the characteristics of chemical sediments. In the diagram of TFe-(CaO+MgO)-SiO2, Hanwang BIF has a consistent distribution area with Wutaishan BIF and other BIF in the world. The REE contents of Hanwang BIF are low, showing characteristics of marine sediments in Archean. In the PAAS-normalized REE pattern, LREE are depleted and HREE are enriched relatively, with strong Eu positive anomaly, obvious Y positive anomaly and no visible Ce anomaly. These Hanwang BIF characteristics are itentical with characteristics of Gongchangling, Wutaishan and many other Archean BIF in the world. A comprehensive study of Hanwang BIF shows that its ferruginous material was associated with volcanic hydrothermal solution and was formed in a marine chemical sedimentary environment. oft-com:office:office" />
