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.

The Penokean orogeny in the Lake Superior region
TL;DR: The Penokean orogeny began at about 1880-Ma when an oceanic arc, now the Pembine-Wausau terrane, collided with the southern margin of the Archean Superior craton marking the end of a period of south-directed subduction as discussed by the authors.

Geology and Stable Isotope Geochemistry of the Biwabik Iron Formation, Northern Minnesota
TL;DR: Oxygen and carbon isotope fractionation between minerals in the Biwabik Iron Formation provides evidence of diagenetic and post-diagenetic processes affecting the rocks.

Chemostratigraphy of Paleoproterozoic carbonate successions of the Wyoming Craton: tectonic forcing of biogeochemical change?
TL;DR: In this paper, carbon isotope values from the upper Nash Fork Formation above the carbonaceous shale have been correlated with those in the Huronian Supergroup, on the southern margin of the Superior Craton.

TL;DR: In this article, a pluton synvolcanique has been found in the Province of Churchill, in the Canadian territory of Nunavut, with an estimated population of 2.61-2.72 million.

Earth's earliest microbial mats in a siliciclastic marine environment (2.9 Ga Mozaan Group, South Africa)
TL;DR: In this article, the authors found evidence for the existence of filamentous bacteria forming sediment-stabilizing mats in shelf environments at 2.9 Ga-the oldest known occurrence of microbial mats in siliciclastic rocks.
