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.

Morphological and ecological complexity in early eukaryotic ecosystems
TL;DR: It is shown that the cytoskeletal and ecological prerequisites for eukaryotic diversification were already established in eukARYotic microorganisms fossilized nearly 1,500 Myr ago in shales of the early Mesoproterozoic Roper Group in northern Australia.
Journal ArticleDOI
History and applications of mass-independent isotope effects
TL;DR: The discovery of the first chemically produced mass-independent isotope effect in 1983 by Thiemens & Heidenreich opened a broad variety of applications, including physical chemistry studies, atmospheric chemistry, paleoclimatology, biologic primary productivity assessment, Solar System origin and evolution, planetary atmospheres (Mars), and the origin of life in Earth's earliest environment.

Late Archean Biospheric Oxygenation and Atmospheric Evolution
Alan J. Kaufman,David T. Johnston,James Farquhar,Andrew L. Masterson,Timothy W. Lyons,Steve Bates,Ariel D. Anbar,Gail Lee Arnold,Jessica Garvin,Roger Buick +9 more
TL;DR: The correlation of the time-series sulfur isotope signals in northwestern Australia with equivalent strata from South Africa suggests that changes in the exogenic sulfur cycle recorded in marine sediments were global in scope and were linked to atmospheric evolution.

The Early Faint Sun Paradox: Organic Shielding of Ultraviolet-Labile Greenhouse Gases
Carl Sagan,Christopher F. Chyba +1 more
TL;DR: It is shown that ultraviolet absorption by steady-state amounts of high-altitude organic solids produced from methane photolysis may have shielded ammonia sufficiently that ammonia resupply rates were able to maintain surface temperatures above freezing.

Variations in the S33, S34, and S36 contents of meteorites and their relation to chemical and nuclear effects
J. R. Hulston,H. G. Thode +1 more
TL;DR: The isotopic ratios S33/S32, S34/S 32, and S36, S32 of the different forms of sulfur in a number of meteorites have been studied as mentioned in this paper.
