Short summary
Despite many articles published about eruptions at Mt. Somma–Vesuvius (SV), the volatile contents of magmas associated with mafic (quasi-primitive) melts were not directly analyzed for many eruptions based on melt inclusions (MIs). We suggest that several high-Fo olivines formed at depths greater than those of the carbonate platform based on MI chemical composition. We also estimated that 347 to 686 t d-1 of magmatic CO2 exsolved from SV magmas during the last 3 centuries of volcanic activity.
