Inverse modelling to unravel the radiogenic isotope signature of mantle sources from evolved magmas: the case-study of Ischia volcano

The active volcano of Ischia, the well-known island off-shore the city of Naples, has had a discontinuous volcanic activity characterised by caldera-forming paroxysmal eruptions, lava flows, and lava domes for >150 kyr. The overall geochemical composition of erupted magmas includes shoshonite, latite, and trachyte/ trachyphonolite. In a complementary study, we demonstrated that the evolution of Ischia trachytes with Sr
