Abstract

Multiple sulfur isotopes ( (super 32) S, (super 33) S, (super 34) S, and (super 36) S) measured on pyrites from the Penglaitan section, the Global Stratotype Section and Point (GSSP) for the Guadalupian-Lopingian Series boundary, and from the auxiliary Tieqiao section in South China show a sulfur isotope signal of negative and positive delta 34S with negative Delta 33S. We suggest that these data indicate mixing of (super 34) S-enriched and (super 34) S-depleted sulfur in the sediments, which may have been driven by shoaling of sulfidic waters. Similar isotopic data of negative delta (super 34) S with negative Delta (super 33) S were also observed from the EF section in the Delaware Basin of west Texas (USA). The consistency of the minor sulfur isotopic anomalies from both South China and west Texas suggests a causal link between widespread shoaling of sulfidic waters and the end-Guadalupian mass extinction.
