6-6-6-6-6-6-6-6-6-6-6-6-6 From: "LORMAND, CHARLINE" <charline.lormand@xxxxxxxxxxxx> Kia ora! The IAVCEI abstract submission deadline is approaching soon and we are inviting all the lovers of microtextures and physical properties of erupted materials to submit their abstract in our session â??*Exploring eruption dynamics through microstructures and physical properties of erupted materials*â?? >From a magma chamber to the Earthâ??s surface, the physical properties of ascending magmas change dramatically through bubble nucleation and growth, outgassing, groundmass crystallization, glass transition, and fragmentation. These processes are recorded by petrographic features in erupted materials, such as microstructures of bubbles and groundmass crystals, compositional zoning of phenocrysts, and volatiles in melt inclusions of phenocrysts and matrix glasses. Conversely, the physical properties of the actual multiphase magmas are affected by bubbles, volatiles, and crystals. Moreover, the totality of these processes influences the eruptive style of volcanoes and the patterns of the geophysical observations at the surface. Approaches employed analyses of microstructures and physical properties of erupted materials in recent studies are diverse, ranging from atomic-scale analyses of melt structures and high-resolution chemical analyses to geodetic observation coupled with the excess-pressure calculation of the magma feeding system. The aim of this session, therefore, is to bring together recent advances in different fields and discuss what we have achieved on the eruption processes so far, and to foresee the future direction. We welcome contributions from a wide range of scientific disciplines, including petrographic analyses of natural samples, laboratory simulation experiments of eruptive processes, interpretations of eruption processes on the basis of geophysical observations, and numerical modeling of magma ascent processes. We are looking forward to seeing you in Rotorua!
