Did Global Glaciation Cause the Great Unconformity?
In a new study, researchers make the case that large-scale glaciation during parts of the Neoproterozoic era led to extensive erosion of Earth’s crust.

Project VoiLA: Volatile Recycling in the Lesser Antilles
Deep water cycle studies have largely focused on subduction of lithosphere formed at fast spreading ridges. However, oceanic plates are more likely to become hydrated as spreading rate decreases.
