Crystallisation conditions of Vesuvius phonolites.

Abstract : Crystallisation experiments have been performed on Mercato (8010 BP), Avellino (3360 BP), Pompei (AD79) and Pollena (AD472) phonolites in order to constrain the pre-eruptive conditions of Plinian events at Vesuvius.We used dry starting glasses prepared from fusing twice powdered pumice at 1 bar, to which various amounts of H2O and CO2 were added to achieve fluid saturation, loaded to Au capsules.
