Sulfur Isotope Evidence for a Geochemical Zonation of the Samoan Mantle Plume
TL;DR: In this article, the authors present multiple sulfur isotope data on sulfide extracted from subaerial and submarine whole rocks associated with several Samoan volcanoes (Malumalu, Malutut, Upolu, Savaii, and Tutuila) that allow an assessment of the S-isotope compositions associated with the different mantle components sampled by the Samoan hotspot.

Effect of Mass-Independent Isotope Fractionation of Sulfur (Δ33S and Δ36S) during SO2 Photolysis in Experiments with a Broadband Light Source
TL;DR: In this article, the behavior of mass-independent isotope effects of sulfur Δ33S and Δ36S during photochemical processes initiated by a broadband ultraviolet radiation was investigated in a flow photochemical reactor using a high-pressure mercury lamp.
Riverine evidence for isotopic mass balance in the Earth's early sulfur cycle
Mark A. Torres,Mark A. Torres,Guillaume Paris,Guillaume Paris,Jess F. Adkins,Woodward W. Fischer +5 more
TL;DR: In this paper, the disappearance of multiple S isotope anomalies from the sedimentary record provides a robust proxy for the timing of the first rise in atmospheric O 2, which has been hypothesized to constrain the early sulfur cycle mass balance.
Journal ArticleDOI
Multiple Sulfur Isotope Geochemistry during the Permian-Triassic Transition
TL;DR: In this article, the authors show that negative ∆33S signals do not correspond clearly to the extinction horizon or to the benthic anoxia/euxinia in the studied sections.
Journal ArticleDOI
Fractal and multifractal analysis of the rise of oxygen in Earth’s early atmosphere
TL;DR: In this paper, the effects of the noise on the time variations of oxygen, carbon and methane for the early Earth are investigated by using fractal and multifractal analysis, and the obtained results demonstrate that the time series as obtained exhibit multifractality caused by long-range time correlations.

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.
