Emplacement of the Franklin large igneous province and initiation of the Sturtian Snowball Earth
During the Cryogenian (720 to 635 Ma ago) Snowball Earth glaciations, ice extended to sea

Continental arc volcanism as the principal driver of icehouse-greenhouse variability
Variations in continental volcanic arc emissions have the potential to control atmospheric
