带状铁建造(BIF)是世界上最大的铁源。它们形成于整个前寒武纪，今天在全球分布在古代克拉通的残骸上。第一个BIF至少可以追溯到39亿到38亿年前。人们对地球历史上这一早期阶段知之甚少，特别是对分子氧O2的存在，因此也对当时BIF的沉积机制知之甚少。
Banded iron formations (BIF) represent the largest source of iron in the world. They formed throughout the Precambrian, and today are globally distributed on the remnants of the ancient cratons. The first BIF dates back to at least 3.9–3.8 billion years. Little is known about this early period in earth’s history, in particular about the presence of molecular oxygen, O2, and therefore also about the deposition mechanisms of BIF at that time.
