Determination of multiple sulfur isotopes in glasses: A reappraisal of the MORB δ34S
TL;DR: In this article, the authors report on improvements to the sulfur extraction method out of silicate glasses by the use of HF+CrCl2 solution for the precise determination of S multi-isotope compositions.

Late Ediacaran redox stability and metazoan evolution
David T. Johnston,Simon W. Poulton,Tatiana Goldberg,Vladimir N. Sergeev,V. N. Podkovyrov,N.G. Vorob'eva,Andrey Bekker,Andrew H. Knoll +7 more
TL;DR: In this paper, a coupled geochemical and paleontological investigation of Neoproterozoic sedimentary rocks from northern Russia is presented, which is consistent with the hypothesis that the pO 2 threshold required for diversification of animals with high metabolic oxygen demands was crossed prior to or during the Ediacaran Period.

Geochemistry of Evaporites and Evolution of Seawater
M. Bąbel,B.C. Schreiber +1 more
TL;DR: The chemistry of modern and ancient evaporites, and their parent waters, is reflected in the mineralogy and facies distribution remaining in the geologic record as mentioned in this paper, which is the key for the understanding of the fossil record.

Sulfur isotopes of organic matter preserved in 3.45-billion-year-old stromatolites reveal microbial metabolism
Tomaso R. R. Bontognali,Alex L. Sessions,Abigail C. Allwood,Woodward W. Fischer,John P. Grotzinger,Roger E. Summons,John M. Eiler +6 more
TL;DR: Positive Δ33S anomalies suggest that disproportionation of elemental sulfur would have been a prominent microbial process in these communities, and are interpreted as recording the process of sulfurization of organic matter by H2S in heterogeneous mat pore-waters influenced by respiratory S metabolism.
Book ChapterDOI
The Geologic History of Seawater
TL;DR: In this article, the authors highlight key insights from the rapid progress of the past decade, focusing on periods of important geochemical changes and how these changes influenced and were influenced by the evolution of life on Earth.

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.
Journal ArticleDOI
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.
