  • The Precambrian banded iron formations (BIFs) are the major iron ore sources on the Earth. They consist of extensive iron-rich and iron-poor layers within siliceous sedimentary rocks1,2. The banding has been attributed to variations in the conditions for precipitation of Fe2+ in ancient seas. The most favoured precipitating agent is oxygen3–8; this would lead in the first place to insoluble FeOOH. The variations might then arise from fluctuations in low levels of oxygen in the atmosphere8… CONTINUE READING
