摘要 | High-resolution delta(13)C data of organic carbon from a continuous section of the Late Ordovician-Early Silurian reveal two positive delta(13)C excursions that are associated with the mass extinction in South China. The first stratigraphic delta(34)S measurements on pyrite tied to well-established biostratigraphy indicate a large perturbation of the sulfur cycle, consistent with major sea-level changes related to the glaciation. The elevated delta(34)S values of pyrites and a large, short-lived negative delta(34)S excursion of similar to 20% associated with the decay of the glaciation suggest deep-water anoxia during the Hirnantian Stage, in contrast to the conventional view that the global oceans were oxygenated. We suggest that deep-water anoxia may have contributed to the Late Ordovician mass extinction in South China and possibly elsewhere. |
