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.

Proterozoic ocean chemistry and evolution: A bioinorganic bridge?
Ariel D. Anbar,Andrew H. Knoll +1 more
TL;DR: Recent data imply that for much of the Proterozoic Eon, Earth's oceans were moderately oxic at the surface and sulfidic at depth, and biologically important trace metals would have been scarce in most marine environments.

2-Methylhopanoids as biomarkers for cyanobacterial oxygenic photosynthesis
TL;DR: It is shown that 2-methylbacteriohopanepolyols occur in a high proportion of cultured cyanob bacteria and cyanobacterial mats and are abundant in organic-rich sediments as old as 2,500 Myr, which may help constrain the age of the oldest cyanobacteria and the advent of oxygenic photosynthesis.

The anaerobic degradation of organic matter in Danish coastal sediments - Iron reduction, manganese reduction, and sulfate reduction
TL;DR: It is speculated that in shallow sediments of the Skagerrak, surface Mn oxides are present in a somewhat reduced oxidation level allowing Mn2+ to escape, and perhaps providing the Mn22+ which enriches sediment of the deep basin, as well as reflecting the saturation by Mn2- of highly reactive surface adsorption sites.

The sulfur cycle of a coastal marine sediment (Limfjorden, Denmark)1
TL;DR: In this paper, the cyclic transformations of inorganic sulfur compounds in the sediments of a Danish fjord were followed for two years and the in situ rate of sulfate reduction measured with a radiotracer technique together with chemical determinations of various sulfur compounds were used to calculate a budget of the complete sulfur cycle.

Mass-independent fractionation of sulfur isotopes in Archean sediments: strong evidence for an anoxic Archean atmosphere.
TL;DR: It is concluded that the atmospheric O2 concentration must have been < 10(-5) PAL prior to 2.3 Ga, which would have meant that all sulfur-bearing species would have passed through the oceanic sulfate reservoir before being incorporated into sediments, so any signature of MIF would have been lost.
