7-7-7-7-7-7-7-7-7-7-7-7-7-7 From: "LLEWELLIN, EDWARD W." <ed.llewellin@xxxxxxxxxxxx> Dear Colleagues, We invite you to submit your abstracts to our session at the IAVCEI Scientific Assembly in Rotorua, New Zealand, 30th Jan - 3rd Feb. * Bubbles in volcanic and magmatic systems * Bubbles play a pivotal role in driving, modulating, and recording volcanic and magmatic processes. They drive eruptions by providing the buoyancy that mobilizes magma from its crustal storage and propels it upwards through the volcanic plumbing system. They modulate the style, intensity, and impact of eruptions by altering the rheology of magma and lava flows, and by creating the over-pressure that causes explosive fragmentation. They record and reveal the history of magma ascent through the textures they create in eruptive products, through their capacity to fractionate, transport, and release the volatile species they contain, and as sources of geophysical signals. Bubbles have relevance, therefore, across the breadth of volcanic and magmatic studies, and act as a common point of reference around which we aim to stimulate interdisciplinary discussion. We invite contributions from researchers and practitioners whose work addresses any aspect of the role of bubbles in magma, including studies of bubbles themselves, and broader studies of magmatic and volcanic processes in which the behaviour of bubbles plays a role. Topic areas include, but are not limited to: 1. The physics of bubbles in magma â?? bubble formation, growth, resorption, deformation, interaction, coalescence, bursting, and their influence on thermal, mechanical and other physical properties of magma. 2. The effect of bubbles on volcanic processes â?? magma mobilization, ascent, convection, mingling, rheology, degassing, outgassing, permeability, fragmentation, and transport of volatiles. 3. The role of bubbles as informers on pre-, syn-, and post-eruptive processes â?? vesicle size, shape, and spatial distributions, spatial distribution of dissolved volatiles, gas geochemistry, bubbles as sources of infrasound and seismicity. We anticipate contributions that adopt a wide range of field, experimental, analytical, and numerical approaches, and particularly encourage contributions that employ novel research methodologies, or that bridge across traditional disciplinary areas. * Submission deadline: 2nd September, 2022 * We hope to see you in New Zealand!
