Tectonics, dynamics and Plio‐Pleistocene magmatism in the central Tyrrhenian Sea: insights from the submarine transitional basalts of the Ventotene volcanic Ridge (Pontine Islands, Italy)
In the Tyrrhenian back-arc basin, the Ventotene Volcanic Ridge (VR) represents a NW-SEoriented
morphological high, located 25 km north of Ventotene Island in the Eastern Pontine Islands.
It is considered part of an alignment of volcanic edifices developed in the central-eastern Tyrrhenian
Sea, from the western Pontine Islands (WPI) to the Campanian Volcanic Region. The samples dredged
along the VR are basalts to trachybasalts belonging to the transitional (TR) rock-series, with a 40Ar-
