Three decades after the discovery of cold seep systems, various sites of hydrocarbon
seepage have been found in the South China Sea (SCS). Over the past decade, these sites …

The oxygen content of the Earth's surface environment is thought to have increased in two
broad steps: the Great Oxygenation Event (GOE) around the Archean–Proterozoic boundary …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

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 …

The competition between sulfate reducing bacteria and methanogens over common
substrates has been proposed as a critical control for methane production. In this study, we …

Long-term secular variation in seawater sulfate concentrations ([SO 4 2−] SW) is of interest
owing to its relationship to the oxygenation history of Earth's surface environment. In this …

The distribution of sulfur isotopes in geological materials reveals information about Earth
history and biogeochemical processes. Research during the last several decades has used …

Sulfate-driven anaerobic oxidation of methane (SO 4-AOM) in marine sediments commonly
leads to the precipitation of pyrite. It is, however, frequently challenging to unequivocally …

A detailed record of the early-Earth sulfur (S) cycle is chronicled by the S isotope values of
sulfide and sulfate preserved in the rock record. Interpretation of this record rests on our …

Sulfur isotope fractionation during dissimilatory sulfate reduction has been conceptually
described by the widely accepted Rees model as related to the stepwise reduction of sulfate …
