Large mass-independent sulphur isotope anomalies link stratospheric volcanism to the late ordovician mass extinction

HIGHLIGHTS

• who: Dongping Hu from the of pyrite with Δ S of up to, ‰ in sedimentary rocks from South ChinaUniversity of have published the research work: Large mass-independent sulphur isotope anomalies link stratospheric volcanism to the Late Ordovician mass extinction, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
• what: The authors report sulphur isotope data (δ34S, Δ33S and Δ36S) of pyrite from two sedimentary successions from South China, and the authors use a characteristic signal of large Δ33S anomalies, resulting from stratospheric photochemical reactions16-20 to constrain the nature of volcanic eruptions during the Late Ordovician.
