- •
We present new Δ17O and coeval 33,34,36S data of Neoproterozoic aged barite from NW Canada.
- •
Through a dynamic 1-box model we demonstrate the sulfate source to global barites was global seawater.
- •
Results suggest a diminished marine sulfate reservoir in the aftermath of the Marinoan glaciation.
