Isotopic evolution of prehistoric magma sources of Mt. Etna, Sicily: Insights from the Valle Del Bove
Mount Etna in NE Sicily occupies an unusual tectonic position in the convergence zone between the African and Eurasian plates, near the Quaternary subduction-related Aeolian arc and above the downgoing Ionian oceanic slab.

Zusammenfassung: | Mount Etna in NE Sicily occupies an unusual tectonic position in the convergence zone between the African and Eurasian plates, near the Quaternary subduction-related Aeolian arc and above the downgoing Ionian oceanic slab. Magmatic evolution broadly involves a transition from an early tholeiitic phase (~500 ka) to the current alkaline phase.
