Atmospheric oxygen abundance, marine nutrient availability, and organic carbon fluxes to the seafloor
TL;DR: The global-scale oxygenation of Earth's surface represents one of the most fundamental chemical transformations in our planet's history as discussed by the authors, and there is empirical and theoretical evidence for at least two...

Multiple sulfur isotopes constraints on origin and evolution of the Neoarchean and Paleoproterozoic Cu-Au systems from the Carajás Domain, Amazonian Craton, Brazil
Érika Suellen Barbosa Santiago,Roberto Perez Xavier,Steffen G. Hagemann,Lena Virgínia Soares Monteiro,J. Cliff +4 more
TL;DR: In this article, multiple sulfur isotopes in sulfides were measured by in situ secondary ion mass spectrometry in order to constrain sulfur sources and pathways, as well as explore atmosphere-ore genesis implications on the metallogeny of the Neoarchean and Paleoproterozoic Cu-Au systems of the Carajas Domain, southeast Amazonian Craton, Brazil.

A simple and rapid ICP-MS/MS determination of sulfur isotope ratios (34S/32S) in complex natural waters: A new tool for tracing seawater intrusion in coastal systems.
TL;DR: In this paper, a collision cell-based ICP-MS/MS approach was used to determine the sulfur isotope abundances (i.e., 34S/32S ratios) in complex coastal waters rapidly, accurately and with minimal sample preparation.

Deposition of sulfate aerosols with positive Δ33S in the Neoarchean
Guillaume Paris,Woodward W. Fischer,Jena E. Johnson,Samuel M. Webb,Theodore M. Present,Alex L. Sessions,Jess F. Adkins +6 more
TL;DR: In this article, carbonate-associated sulfate (CAS) in Neo-archean rocks showed no such negative values, but rather the opposite, as secondary processes tend to either remove CAS from the sample and/or decrease the 33S-enrichment.
Lessons from Venus on Oceans and the Sulfur Cycle: Sulfate Aerosol Hazes and SO2 Gas as Constraints on Rocky Exoplanets' Surface Liquid Water
TL;DR: In this article, the authors examined the fundamentals of the sulfur cycle on a rocky planet with an ocean and an atmosphere in which the dominant forms of sulfur are SO2 gas and H2SO4-H2O aerosols (as on Earth and Venus).

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.

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.
