Large sulfur isotope fractionation does not require disproportionation
The composition of sulfur isotopes in sedimentary sulfides and sulfates traces the sulfur
cycle throughout Earth's history. In particular, depletions of sulfur-34 (34S) in sulfide relative …

Oxidation of the Ediacaran ocean
Oxygenation of the Earth's surface is increasingly thought to have occurred in two steps. The
first step, which occurred∼ 2,300 million years (Myr) ago, involved a significant increase in …

Stable isotopic and metagenomic analyses reveal microbial-mediated effects of microplastics on sulfur cycling in coastal sediments
H Wang, Q Yang, D Li, J Wu, S Yang… - Environmental …, 2023 - ACS Publications
Microplastics are readily accumulated in coastal sediments, where active sulfur (S) cycling

Biogeochemistry of sulfur isotopes
DE Canfield - Reviews in mineralogy and geochemistry, 2001 - pubs.geoscienceworld.org
Sulfur, with an atomic weight of 32.06, has four stable isotopes. By far the most abundant is
32 S, representing around 95% of the total sulfur on Earth. The next most abundant isotope …

Influence of sulfate reduction rates on the Phanerozoic sulfur isotope record
Phanerozoic levels of atmospheric oxygen relate to the burial histories of organic carbon
and pyrite sulfur. The sulfur cycle remains poorly constrained, however, leading to …
