Stretching the Envelope of Past Surface Environments: Neoproterozoic Glacial Lakes from Svalbard
The oxygen isotope composition of terrestrial sulfate is affected measurably by many Earth-surface processes. During the Neoproterozoic, severe “snowball” glaciations would have had an extreme impact on the biosphere and the atmosphere. Here, we report that sulfate extracted from carbonate lenses wi...

The oxygen isotope composition of terrestrial sulfate is affected measurably by many Earth-surface processes. During the Neoproterozoic, severe “snowball” glaciations would have had an extreme impact on the biosphere and the atmosphere.
