摘要

Late Achaean to Palaeoproterozoic deposition of banded iron formations （BIF） is the most important iron ore resource on Earth. As evident by stable isotopes compositions, fossil molecule, rock magnetic properties, microorganisms such as cyanobacteria, iron-oxidizing and iron-reducing bacteria are suggested to have participated in the deposition of BIF. In this review, the authors briefly introduced the global distribution of BIF and the environments of early Precambrian Earth. Then, the authors went through the recent studies on bacterial mineralization related to the deposition of banded iron, including oxygenic/anoxygenic photosynthesis and dissimilatory iron reduction. Finally, the authors proposed some challenges and prospectives.
