BeschreibungThe Pontine Islands are Plio-Pleistocene in age, ranging from 4.2-1.0 Ma (Scandone, 1987, pers. comm.; Peccerillo, 2005). The islands are mostly formed of Pliocene rhyolites and Pleistocene trachytes and alkaline rhyolites. Volcanic products also consist of obsidian lava flows, domes, dykes, breccias, and hydromagmatic products. The rhyolitic volcanic activity on Ponza occured between 4.2 and 3.0 Ma, followed by trachytic activity at about 1.0 Ma. The eruptive activity on Palmarola occured around 1.6 Ma (Peccerillo, 2005).
