Are long-term trends in the sulfur isotope composition of ...
The sulfur isotope record of Cretaceous marine sulfate exhibits a 5 permil negative excursion that persisted for ~25 million years (~125-100 Ma) and is the largest identified in the sedimentary record spanning the last ~125 million years. Recent work has suggested that this excursion resulted from massive evaporite deposition associated with rifting during the opening of the …
