Cupaello is responsible for a 750-m-long lava flow that covers layers of pyroclastic material, including ash, breccias, lapilli, and scoria. These products were channelized and accumulated downslope of the volcanic edifice (Stoppa and Cundari, 1995). These pyroclastics are carbonatitic in composition, and yielded an Ar/Ar age of 639 ka (Peccerillo, 2005). However, Stoppa and Cundari (1995) list a date of about 491 +/- 3 ka. Structures within the pyroclastic layers indicate that the tuff could still deform plastically when covered by the lava, suggesting that both the explosive and effusive phases were part of the same eruption (Stoppa and Cundari, 1995).
