The Archean atmosphere

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

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

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

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.

Suboxic diagenesis in banded iron formations.

TL;DR: The electron acceptor that permits oxidation in the absence of free oxygen is presumed to be iron(III) which may have been significantly more abundant in the initial chemical precipitate than in the post-diagenetic sedimentary rock.

Sulfur record of rising and falling marine oxygen and sulfate levels during the Lomagundi event

TL;DR: Coupled stable isotope data for carbonate carbon and carbonate-associated sulfate shows trends in C and S isotope values that track the isotopic evolution of seawater sulfate and reflect an increase in pyrite burial and a crash in the marine sulfate reservoir during ocean deoxygenation in the waning stages of the positive carbon isotope excursion.

Silicon isotopic fractionation during adsorption of aqueous monosilicic acid onto iron oxide

TL;DR: In this article, the authors report on the Si-isotopic fractionation during H4SiO40 adsorption on synthesized ferrihydrite and goethite in batch experiment series designed as function of time (0-504 h) and initial concentration (ic) of Si in solution (0.21-1.80 mM).
Journal ArticleDOI

An iron shuttle for deepwater silica in Late Archean and early Paleoproterozoic iron formation

TL;DR: In this article, the authors present a conceptual model of iron formation that offers insight into the deposition of silica, based on the proclivity of dissolved silica to adsorb onto the hydrous surfaces of ferric oxides.
