The Archean atmosphere
David C. Catling,Kevin Zahnle +1 more
TL;DR: The Archean eon data imply that substantial loss of hydrogen oxidized the Earth, and detailed understanding of the coevolving solid Earth, biosphere, and atmosphere remains elusive, however.

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
Reverse weathering as a long-term stabilizer of marine pH and planetary climate
Terry T. Isson,Noah J. Planavsky +1 more
TL;DR: Elevated rates of reverse weathering within silica-rich oceans led to enhanced carbon retention within the ocean–atmosphere system, promoting a stable, equable ice-free climate throughout Earth’s early to middle ages.
Evidence for free oxygen in the Neoarchean ocean based on coupled iron-molybdenum isotope fractionation
Andrew D. Czaja,Clark M. Johnson,Eric E. Roden,Brian L. Beard,Andrea R. Voegelin,Thomas F. Nägler,Nicolas J. Beukes,Martin Wille +7 more
TL;DR: In this article, a combination of Fe and Mo isotope systematics of Ca-Mg carbonates and shales from the 2.68 to 2.50 Ga Campbellrand-Malmani carbonate platform of the Kaapvaal Craton in South Africa was used to constrain free O2 levels in the photic zone of a Late Archean marine basin by the combined use of Fe-Mo isotope systems.

Late Archean euxinic conditions before the rise of atmospheric oxygen
C. Scott,Andrey Bekker,Christopher T. Reinhard,Bernhard Schnetger,Bryan Krapez,Douglas Rumble,Timothy W. Lyons +6 more
TL;DR: In this article, the authors present a multielement (C-S-Fe-Mo) biogeochemical study of ca. 2662 Ma shales from the Hamersley Province in Western Australia and reveal a sustained episode of Fe-limited pyrite formation under an anoxic and sulfidic (euxinic) water column.

Sedimentology of the Kuruman and Griquatown Iron-formations, Transvaal Supergroup, Griqualand West, South Africa
TL;DR: A subsequent transgression resulted in the deposition of open shelf iron-formation on top of the Campbellrand carbonate platform as discussed by the authors, and an ironformation sequence represented by the Kuruman and Griquatown Iron-formations was deposited.

Origin of Precambrian iron formations

TL;DR: In this article, a model is proposed by which lateritic weathering in a reducing atmosphere yields solutions with Fe and Ca in approximately their 1:1 ratio of crustal abundance.

Palaeoenvironmental significance of rounded pyrite in siliciclastic sequences of the Late Archaean Witwatersrand Basin: oxygen‐deficient atmosphere or hydrothermal alteration?
TL;DR: Petrographic and sulphur isotope studies support the long-held contention that rounded grains of pyrite in siliciclastic sequences of the Late Archaean Witwatersrand Supergroup originated as placer grains as discussed by the authors.
