Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Quantifying the rates of biogeochemical processes in marine sediments is essential for
understanding global element cycles and climate change. Because organic matter …

Reconstructions of coupled carbon, oxygen, and sulfur cycles rely heavily on sedimentary
pyrite sulfur isotope compositions (δ34Spyr). With a model of sediment diagenesis, paired …

Abstract Models test our understanding of processes and can reach beyond the spatial and
temporal scales of measurements. Multi-component Reactive Transport Models (RTMs) …

Two Permian/Triassic boundary sections in central Japan provide a rare window into
environmental conditions within the Panthalassic Ocean, which encompassed more than …

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 …

Literature data on benthic dissolved iron (DFe) fluxes (µmol m− 2 d− 1), bottom water
oxygen concentrations (O2BW, μM), and sedimentary carbon oxidation rates (COX, mmol …

The sulfate–methane transition (SMT) zone is a diagenetic transition within anoxic marine
sediments created by the metabolic activity of a consortium of sulfate-reducing bacteria and …

The sulfur cycle is an important, although understudied facet of today's modern oxygen
minimum zones (OMZs). Sulfur cycling is most active in highly productive coastal OMZs …

Fluid-rock interaction (or water-rock interaction, as it was more commonly known) is a
subject that has evolved considerably in its scope over the years. Initially its focus was …
