Abstract

The sulfur isotopic composition has been determined for terminal Neoproterozoic to early Cambrian evaporites from the Hanseran Group in NW India. delta S-34 values, ranging from + 27.5 parts per thousand to + 39.7 parts per thousand vs. Canyon Diablo Troilite (CDT) (n = 26) further substantiate thestrongly positive sulfur isotope signature of contemporaneous seawater. Distinct stratigraphic variations in delta S-34 within this succession suggest secular variations in seawater composition which might be of global importance. Overall, this documents major pertubations of the sulfur cycle in response to paleooceanographic changes trailing tectonic, climatic and/or biological rearrangements during the Neoproterozoic and early Paleozoic.
