Abstract: Abstract In this study, we report multiple S-isotopic data (δ34S and Δ33S) of sedimentary pyrite in Early to Late Ordovician sections from South China. The results reveal two distinct groups of negative Δ33S anomalies during… read more here.

Abstract: Abstract The diversity of nitrogen-based dissimilatory metabolisms in anoxic waters continues to increase with additional studies to the marine oxygen deficient zones (ODZs). Although the microbial oxidation of nitrite (NO2–) has been known for over… read more here.
