| Amiata is a lava dome complex located about 20 km NW of Lake Bolsena in the southern Tuscany region of Italy. The 1738-m-high trachydacitic domes and associated lava flows were erupted along regional ENE-WSW-trending faults. The largest of the domes is 1738-m-high Monte Amiata (La Vetta), the 2nd highest volcano in Italy and a compound lava dome with a trachytic lava flow that extends to the east. A massive viscous trachydacitic lava flow, 5 km long and 4 km wide, is part of the basal complex and extends from beneath the southern base of Corno de Bellaria dome. Radiometric dates indicate that the Amiata complex had a major eruptive episode about 300,000 years ago. No eruptive activity has occurred at Amiata during the Holocene, but thermal activity including cinnabar mineralization continues at a producing geothermal field near the town of Bagnore, at the SW end of the dome complex. | |||
