Background
Filicudi was formed from the coalescence of eruptive centers that developed as part of a NW-SE elongated volcanic complex (Peccerillo, 2005; Guest et al., 2003). It's volcanic structures include basaltic to andesitic composite cones and dacitic domes, lava flows, and pyroclastics (Peccerillo, 2005). The Filicudi rocks also often contain igneous and metamorphic xenoliths (Peccerillo, 2005). Potassium-Argon dates of 0.170 and 0.166 million years were obtained by Capaldi et al. (1985), but Peccerillo (2005) gives a general age range of 440-40 ka. Tephrochronology indicates that the youngest eruptions occurred less than 35,000 years ago (Keller, 1989, pers. comm.). The Eruptive history is generally broken into four phases. The first (1.02 Ma) consisted of pyroclastic eruptions followed by lava flows. The second (390 ka) produced lava flows. The third is responsible for the construction of Fossa Felci, the main volcanic edifice on the island, and the production of basaltic andesitic lavas and pyroclastics. The fourth (40 ka) involved explosive activity from Fossa Felci, creating pumiceous pyroclastics (Guest et al., 2003).---
