Laura Spina

My research topics deal with the effects of different decompression paths on the bubble dynamics (i.e., nucleation, growth, coalescence and fragmentation) in magma. In order to analyze the dynamics of magmatic fluid subjected to various decompression histories, a properly developed shock tube will be used. Decompression experiments will be carried out on synthetic analog material, likewise silicon oil plus analog-crystals, as well as on experimentally hydrated silicate melts of phonolitic composition, and natural melts. In order to shed light on the ongoing fluid dynamics we will use an high speed camera. Further, the product of fragmented magma, will be properly analyzed.
