Introduction

Torre Alfina is a monogenetic volcano consisting of two volcanic necks and a lava flow several hundred meters long located SE of Monte Amiata (Peccerillo, 2005). Both blocky lava flows and smoother flows formed from lower viscosity lava crop out within a few kilometers of the volcano, and lapilli and scoria deposits surround the vent. Some lava tubes are also present in the eastern part of the lava field near the Paglia River canyon (Conticelli, 1998). These lavas are potassic alkaline olivine-latites and have been dated at 0.9-0.82 Ma (Conticelli, 1998; Peccerillo, 2005). Torre Alfina rocks contain a large number of crustal and mantle xenoliths (Conticello et al., 1998).
