DOI: 10.1016/j.gca.2019.08.031
Abstract: Abstract Banded iron formations (BIFs) are Fe- and Si-rich chemical sediments that were deposited in the oceans throughout the Archean Eon (4.0–2.5 billion years ago; Ga). Despite extensive research pertaining to their composition, mineralogy and… read more here.

DOI: 10.1016/j.gsf.2017.02.008
Abstract: Abstract Estimates of early atmosphere compositions from metamorphosed banded iron formations (BIFs) including the well-studied ≥3.7 BIFs of the Isua supracrustal belt (Greenland) are dependent on knowledge of primary versus secondary Fe-mineralogical assemblages. Using new… read more here.
