[HTML][HTML] A global reassessment of the controls on iron speciation in modern sediments and sedimentary rocks: A dominant role for diagenesis
The speciation of iron in sediments and sedimentary rocks is a widely used proxy for the
chemistry and oxidation state of ancient water bodies. Specifically, the fraction of reactive …

Deconvolving microbial and environmental controls on marine sedimentary pyrite sulfur isotope ratios
Reconstructions of past environmental conditions and biological activity are often based on
bulk stable isotope proxies, which are inherently open to multiple interpretations. This is …

Early diagenesis of iron and sulfur in Bornholm Basin sediments: The role of near-surface pyrite formation
Pyrite formation in marine sedimentary environments plays a key role in the global
biogeochemical cycles of carbon, sulfur and iron, regulating Earth's surface redox balance …

Isotopically “heavy” pyrite in marine sediments due to high sedimentation rates and non-steady-state deposition
Sedimentary pyrite formation links the global biogeochemical cycles of carbon, sulfur, and
iron, which, in turn, modulate the redox state of the planet's surficial environment over …

Organic matter sulfurization and organic carbon burial in the Mesoproterozoic
Abstract Throughout the Proterozoic Era, sedimentary organic carbon burial helped set the
pace of global oxygenation and acted as a major modulator of atmospheric CO 2 and …

Novel sulfur isotope analyses constrain sulfurized porewater fluxes as a minor component of marine dissolved organic matter
Marine dissolved organic matter (DOM) is a major reservoir that links global carbon,
nitrogen, and phosphorus. DOM is also important for marine sulfur biogeochemistry as the …
