TLDR
In this article, the authors show that electron transfer from organic carbon to Fe(III) minerals during temperature/pressure diagenesis can drive the production of key BIF minerals.About:

TL;DR: A review of the defining features of iron formations and their distribution through the Neo-archaean and Palaeoproterozoic is presented in this article, along with an update of previous reviews by Bekker et al. (2010, 2014).
Book
Atmospheric Evolution on Inhabited and Lifeless Worlds
TL;DR: In this article, the authors present a survey of the current understanding of the atmospheric evolution and climate on Earth, on other rocky planets within our Solar System, and on planets far beyond.
Iron and Carbon Isotope Evidence for Microbial Iron Respiration Throughout the Archean
Paul R. Craddock,Nicolas Dauphas +1 more
TL;DR: In this article, the authors reported the results of a study of the early Archean BIFs from the Hamersley Basin, Australia and the early Isua Supracrustal Belt (ISB), Greenland.
Journal ArticleDOI
Biogenic Fe(III) minerals: From formation to diagenesis and preservation in the rock record
TL;DR: In this article, the role of Fe(II)-oxidizing bacteria in the deposition of ancient banded iron formations (BIF) is discussed, with the main challenge of separating biogenic from abiogenic processes over deep time.
Journal ArticleDOI
Experimental diagenesis of organo-mineral structures formed by microaerophilic Fe(II)-oxidizing bacteria
TL;DR: It is suggested that iron minerals might play a role in maintaining the structural and chemical integrity of stalks under diagenetic conditions and provide spectroscopic signatures for the search of ancient life in the rock record.

TL;DR: In this article, ion-microprobe measurements of the carbon-isotope composition of carbonaceous inclusions within grains of apatite (basic calcium phosphate) from the oldest known sediment sequences a approx. 3,800 Myr-old banded iron formation from the Isua supracrustal belt, West Greenland and a similar formation from Akilia island that is possibly older than 3,850 Myr.

2-Methylhopanoids as biomarkers for cyanobacterial oxygenic photosynthesis
TL;DR: It is shown that 2-methylbacteriohopanepolyols occur in a high proportion of cultured cyanob bacteria and cyanobacterial mats and are abundant in organic-rich sediments as old as 2,500 Myr, which may help constrain the age of the oldest cyanobacteria and the advent of oxygenic photosynthesis.

TL;DR: Profiles of the phospholipid ester-linked fatty acids indicated that both the anaerobic desaturase and the branched pathways for fatty acid biosynthesis were operative, and the 16S rRNA sequence indicated that this organism belongs in the delta proteobacteria.
