Sedimentary pyrite sulfur isotopes track the local dynamics of the Peruvian oxygen minimum zone [PDF]
Nature Communications, 2021 To explore the importance of local vs. global sulfur-cycle controls on variations in pyrite sulfur isotopes, the authors couple carbon-nitrogen-sulfur concentrations and stable isotopes of sediments from the Peruvian oxygen minimum zone, identifying a ...

Recombination Reactions as a Possible Mechanism of Mass-Independent Fractionation of Sulfur Isotopes in the Archean Atmosphere of Earth [PDF]
Proc Natl Acad Sci U S A, 2017 A hierarchy of isotopically substituted recombination reactions is formulated for production of sulfur allotropes in the anoxic atmosphere of Archean Earth.

Coupled sulfur-silicon isotopes reveal supracrustal origin of Archean continents [PDF]
Nature CommunicationsThe genesis of Archean continental crust through partial melting of hydrous mafic protolith is widely acknowledged, yet the origin of the mafic protolith remains highly contentious.

Molecular insights into the dynamic relationship between respiration rate and sulfur isotope effect [PDF]
Applied and Environmental MicrobiologyMicrobial sulfate reduction and its resulting sulfur isotope effects are crucial for understanding the past and present sulfur cycle. Microbial S-isotope effects have often been explained by their inverse correlation with the cell-specific sulfur ...

Sulfur isotopes in coal constrain the evolution of the Phanerozoic sulfur cycle. [PDF]
Proc Natl Acad Sci U S A, 2013 Sulfate is the second most abundant anion (behind chloride) in modern seawater, and its cycling is intimately coupled to the cycling of organic matter and oxygen at the Earth’s surface. For example, the reduction of sulfide by microbes oxidizes vast amounts of organic carbon and the subsequent reaction of sulfide with iron produces pyrite whose burial ...

Wet feet: developing sulfur isotope provenance methods to identify wetland inhabitants
Royal Society Open Science, 2023 The stable isotopes of sulfur provide a distinctive signature for marine proximity and interaction. Exploring coastal proximity has been the principal application of sulfur isotopes in archaeology and palaeoecology, but this deals only with high (greater

Sulfur Stable Isotope Discrimination in Rice: A Sulfur Isotope Mass Balance Study
Frontiers in Plant Science, 2022 The use of sulfur (S) stable isotopes to study S metabolism in plants is still limited by the relatively small number of studies. It is generally accepted that less S stable isotope discrimination occurs during sulfate (SO42–) uptake. However, S metabolism and allocation are expected to produce separations of S stable isotopes among the different plant
