Isotopic compositions of Mn-carbonate and organic carbon from the same individual samples and sulfur isotopic compositions of pyrites in the basal Datangpo Formation were analyzed. Highly 34S-enriched pyrites （834Spyrite =31.7-59.4‰） were precipitated in rel- atively occlusive pore water under anoxi...
