Monte Somma, Complesso del Somma-Vesuvio, Napoli, Campania, Italia

Monte Somma is an igneous, arc-shaped mountain that represents the remnants of an older volcanic cone destroyed in a cataclysmic event in 79 d.c. (when Pompei and Ercolano were destroyed and where Plinius the Old died trying to study the eruption). Mt. Vesuvius is the current cone over the vent. Last eruption 1944.

N.B.: The "guarinite" of Somma-Vesuvius Complex is an epitaxy of hiortdahlite, wöhlerite and låvenite (Russo & Punzo, 2004 and references herein).
