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.

Evidence of atmospheric sulphur in the martian regolith from sulphur isotopes in meteorites
TL;DR: Measurements of sulphur isotopes in oxidized and reduced phases from the SNC meteorites are presented together with the results of laboratory photolysis studies of two important martian atmospheric sulphur species (SO2 and H2S), which identify a mechanism for producing large abiogenic 34S fractionations in the surface sulphur reservoirs.
Journal ArticleDOI
Anoxygenic photosynthesis modulated Proterozoic oxygen and sustained Earth's middle age
TL;DR: It is argued that the proportional contribution of anoxygenic photosynthesis to overall primary production would have influenced oceanic redox and the Proterozoic O2 budget, paving the way for the further oxygenation of the oceans and atmosphere and, ultimately, the evolution of complex multicellular organisms.

Reconstructing Earth's surface oxidation across the Archean-Proterozoic transition

TL;DR: In this article, the earliest recorded positive carbon isotope anomaly was found in the Transvaal Supergroup of South Africa, in phase with sulfur isotopes, and the authors linked these environmental perturbations to the Great Oxidation Event (ca. 2.3 Ga).
Journal ArticleDOI
A late Archean sulfidic sea stimulated by early oxidative weathering of the continents.
TL;DR: Findings indicate that euxinic conditions may have been common on a variety of spatial and temporal scales both before and immediately after the Paleoproterozoic rise in atmospheric oxygen, hinting at previously unexplored texture and variability in deep ocean chemistry during Earth’s early history.

Gas Souring by Thermochemical Sulfate Reduction at 140¡C: Reply
TL;DR: In this paper, the authors show that the temperature required for in-situ thermochemical sulfate reduction to produce the high H2S concentrations encountered in deep carbonate gas reservoirs is greater than 140°C.
