英文摘要	A new set of delta(34)S(sulfide), delta(34)S(sulfate) and delta(13)Carbonate values has been reported from Neoproterozoic sedimentary rocks in southern China. The interglacial black shales of the Datangpo Fm display higher delta(34)S(sulfide) values with > + 20parts per thousand average, but the post-glacial black shales from the Doushantuo Fm. show negative delta(34)S(sulfide) values. However, the Jinjiadong Fm., the same post-glaciation as the Doushantuo Fm., has positive delta(34)S(sulfide) values, implying that the delta(34)S value of sedimentary sulfides would be controlled by lithofacies and paleogeographic environments. The delta(34)S(sulfate) values relative to a delta(13)C(carbonate) were obtained by extraction of trace sulfate from the successive carbonate sequences in the Yangtze Gorges sections. A preliminary interpretation suggests that the oceanic environment may fluctuate dramatically at the post-glacial Doushantuo stage and, then, recover its stability at the Dengying stage on the basis of the high resolution delta(34)S and delta(13)C curves of seawater.
