Sabatini District

The Sabatini Volcanic District developed between about 0.8-0.6 Ma and 40 ka over a wide area located just to the north of Rome. Volcanism was predominantly explosive and generated widespread pyroclastic deposits with only minor lava flows, which were emitted from a large number of centres including several calderas (e.g. De Rita et al. 1983, 1993). The vol-canism occurred along a zone of crosscutting NW-SE and NE-SW faults (Di Filippo 1993). The Sabatini rocks rest over the same type of sedimentary bedrocks as at Vico, as well over the acid volcanics of Tolfa-Manziana-Cerite complex of the Tuscany Province.
