Rethinking the Ancient Sulfur Cycle
TL;DR: In this article, the deep-time δ34S record of marine sulfates and sulfides is reviewed in light of recent advances in understanding the sulfur biogeochemical cycle.
Journal ArticleDOI
Influence of sulfate reduction rates on the Phanerozoic sulfur isotope record
TL;DR: Experiments linking the magnitude of fractionations of the multiple sulfur isotopes to the rate of microbial sulfate reduction demonstrate that such fractionations are controlled by the availability of electron donor (organic matter), rather than by the concentration of electron acceptor (sulfate), an environmental constraint that varies among sedimentary burial environments.

Rapid oxygenation of Earth’s atmosphere 2.33 billion years ago
Genming Luo,Genming Luo,Shuhei Ono,Nicolas J. Beukes,David T. Wang,Shucheng Xie,Roger E. Summons +6 more
TL;DR: The new data suggest that the oxygenation occurred rapidly—within 1 to 10 million years—and was followed by a slower rise in the ocean sulfate inventory, whereas the relationships among GOE, “Snowball Earth” glaciation, and biogeochemical cycling will require further stratigraphic correlation supported with precise chronologies and paleolatitude reconstructions.

A Post-Genomic View of the Ecophysiology, Catabolism and Biotechnological Relevance of Sulphate-Reducing Prokaryotes
Ralf Rabus,Sofia S. Venceslau,Lars Wöhlbrand,Gerrit Voordouw,Judy D. Wall,Inês A. C. Pereira +5 more
TL;DR: The wealth of publications in this period is a testimony to the large environmental, biogeochemical and technological relevance of these organisms and how much the field has progressed in these years, although many important questions and applications remain to be explored.

Anomalous sulphur isotopes in plume lavas reveal deep mantle storage of Archaean crust
Rita A. Cabral,Matthew G. Jackson,Estelle Rose-Koga,Kenneth T. Koga,Martin J. Whitehouse,Martin J. Whitehouse,Michael A. Antonelli,James Farquhar,James M.D. Day,Erik H. Hauri +9 more
TL;DR: Anomalous sulphur isotope signatures indicating mass-independent fractionation (MIF) in olivine-hosted sulphides from 20-million-year-old ocean island basalts from Mangaia, Cook Islands (Polynesia), which have been suggested to sample recycled oceanic crust, suggest that sulphur was subducted into the mantle before 2.45 billion years ago and recycled into theantle source of Mangaia lavas.

Volcanic degassing, hydrothermal circulation and the flourishing of early life on Earth: A review of the evidence from c. 3490-3240 Ma rocks of the Pilbara Supergroup, Pilbara Craton, Western Australia
TL;DR: In the case of the Warrawoona Group of the Pilbara Craton, the authors of as discussed by the authors show that most bedded chert units originated as epiclastic and evaporative sedimentary rocks that were silicified by repeated pulses of hydrothermal fluids that circulated through the footwall basalts during hiatuses in volcanism.
Journal ArticleDOI
Hypersulfidic deep biosphere indicates extreme sulfur isotope fractionation during single-step microbial sulfate reduction
TL;DR: In this article, the isotopic differences between sulfate and the reduced sulfur species can also be generated during microbial single-step fractionation, which indicates that the sulfate-reducing communities and/or their cellular metabolic activities in the deep biosphere may differ from those observed in near-surface sediments or the water column.

Isotopic evidence for Mesoarchaean anoxia and changing atmospheric sulphur chemistry
James Farquhar,Marc Peters,David T. Johnston,Harald Strauss,Andrew L. Masterson,Uwe Wiechert,Alan J. Kaufman +6 more
TL;DR: The findings point to the persistence of an anoxic early atmosphere, and identify variability within the isotope record that suggests changes in pre-2.45-Gyr-ago atmospheric pathways for non-mass-dependent chemistry and in the ultraviolet transparency of an evolving early atmosphere.
Journal ArticleDOI
Sulfur isotope fractionation during bacterial reduction and disproportionation of thiosulfate and sulfite
TL;DR: In this article, the authors measured sulfur isotope fractionation during transformations of thiosulfate (S2O32−) and sulfite (SO32−), pathways which may be of considerable importance in the cycling of sulfur in marine sediments and euxinic waters.

Stable Isotopes in Seafloor Hydrothermal Systems: Vent fluids, hydrothermal deposits, hydrothermal alteration, and microbial processes
TL;DR: Bostrom et al. as mentioned in this paper found evidence for extensive and widespread Fe-rich metalliferous sediments on the seafloor with a distribution strongly correlated with the mid-ocean ridges.
