The Campania Province, Pontine Islands, Mount Vulture

Volcanic rocks in Campania and Pontine Islands range from mafic to felsic and mostly have silica undersaturated potassic to ultrapotassic compositions (Fig. 6.2). Mafic rocks with K2O contents close to calc-alkaline basalts have been found both as lavas and as lithic ejecta at Ventotene and Procida-Vivara. Pliocene (about 4.5 Ma) calc-alkaline rhyolites occur at Ponza, and 2 Ma old calc-alkaline basalts to andesites have been found by borehole drilling beneath the Campanian Plain north of Campi Flegrei. 

A summary of the ages and compositional characteristics of volcanism in Campania, the Pontine Island and Vulture is given in Table 6.1. Data on representative rocks are reported in Table 6.2.
