Introduction. The sulfur cycle of marine sediments is primarily driven by the dissimilatory sulfate reduction (DSR) to sulfide by anaerobic microorganisms (e.g., Jørgensen and …
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 …

Living organisms transform sulfur from one oxidation state to another, thus changing the chemical properties of sulfur compounds and their distribution in the atmosphere, soils, …
Sulfur cycling is ubiquitous in sedimentary environments, where it mediates organic carbon remineralization, impacting both local and global redox budgets, and …
