Ascent of Stromboli yellow pumice magmas : experimental simulation at P<=4 KB.

Abstract : Stromboli volcano is characterised by a persistent, mildly explosive activity producing a crystal-rich HK- basaltic scoria. The normal activity is periodically interrupted by more energetic explosions during which a crystal-poor HK basaltic pumice is emitted (yellow pumice), often intermingled with the crystal-rich scoria. We experimentally investigated the ascent path of the yellow pumice from the inferred depth of segregation ˜12 km to a very shallow level, where it interacts with the already degassed resident magma.
