Crystallization of magma during magma ascent in the conduit has a large impact on the dynamics of volcanic eruptions. Magma viscosity and brittleness increase with crystallization. This change of rheological properties may cause brittle fragmentation of low-viscosity basaltic magma during highly explosive subplinian and Plinian eruptions. On the other hand, crystallization may form rigid crystal frameworks, causing efficient outgassing through the interaction between the crystal frameworks and growing gas bubbles in ascending magma, resulting in effusive eruptions. This session aims to integrate information of elementary processes to develop physical models of multiphase magma ascent and eruption. In this view, we welcome innovative and multidisciplinary contributions from experimental volcanologists, numerical modelers, petrologists, and also geophysicists who develop and extend techniques to explore crystallization and bubble-crystal interactions, and their effects on fragmentation and outgassing of multiphase magma during effusive and explosive eruptions.
