Coupled Fe and S isotope variations in pyrite nodules from Archean shale
Johanna Marin-Carbonne,Claire Rollion-Bard,Andrey Bekker,Olivier Rouxel,Andrea Agangi,Barbara Cavalazzi,Cora C. Wohlgemuth-Ueberwasser,Axel Hofmann,Kevin D. McKeegan +8 more
TL;DR: In this paper, the authors illustrate the importance of in-situ and coupled study of Fe and S isotopes on two pyrite nodules in a c. 2.7 Ga shale from the Bubi Greenstone Belt (Zimbabwe).
Journal ArticleDOI
Production, preservation, and biological processing of mass-independent sulfur isotope fractionation in the Archean surface environment
TL;DR: A detailed model of the marine sulfur cycle is used to propagate and distribute atmospherically derived S MIF from its delivery to the ocean to its preservation in the sediment, which is predicted to be most highly variable in nonmarine and shallow-water settings.
Journal ArticleDOI
Photochemistry of Sulfur Dioxide and the Origin of Mass-Independent Isotope Fractionation in Earth's Atmosphere
TL;DR: In this article, the authors discuss the emerging picture of the physical origins of S-MIF and their implications for the chemistry of the early Earth's atmosphere, including isotopologue-dependent self-shielding, cross-sectional amplitudes, and vibronic coupling during intersystem crossing.

Multiple sulfur isotopes monitor fluid evolution of an Archean orogenic gold deposit
Crystal LaFlamme,Dennis Sugiono,Nicolas Thébaud,Stefano Caruso,Marco L. Fiorentini,Vikraman Selvaraja,Heejin Jeon,Francois Voute,Laure Martin +8 more
TL;DR: In this article, a gold-bearing laminated quartz breccia ore zone and its sulfide-bearing alteration halo in the (+6 Moz Au) structurally-controlled Archean Waroonga deposit located in the Eastern Goldfields Superterrane of the Yilgarn Craton, Western Australia were investigated.
Journal ArticleDOI
A multiple sulfur and organic carbon isotope record from non-conglomeratic sedimentary rocks of the Mesoarchean Witwatersrand Supergroup, South Africa
TL;DR: In this article, multiple sulfur isotope ratios (36S/34S/33S/32S) and organic carbon isotope ratio (13C/12C) were measured from 198 non-conglomeratic sedimentary samples that were collected from five deep diamond drill-cores that cover the majority of the ca. 2.82 Ga Witwatersrand Supergroup.

Geochemistry of Hydrothermal Ore Deposits
TL;DR: In this paper, Skinner et al. discuss the relationship between hydrous alteration and its relationship to hydrous fluid composition in the formation of sulfide-sulfide ores.

Sedimentary pyrite formation: An update
TL;DR: In this article, it was shown that organic matter appears to be the major control on pyrite formation in normal (non-euxinic) terrigenous marine sediments where dissolved sulfate and iron minerals are abundant.
Journal ArticleDOI
The age curves of sulfur and oxygen isotopes in marine sulfate and their mutual interpretation
TL;DR: In this article, a model involving symmetrical fluxes is introduced to take advantage of the oxygen data, and the measured δ34S and δ18O correspond to variations in these isotopes in sulfate of the world ocean surface.
