The exsolution and escape of volatiles during magma ascent
Convener: Felix W. von Aulock
Co-Conveners: Kim Berlo, Iona McIntosh, Kelly Russell, James Watkins
The exsolution and escape of volatiles drives both
effusive and explosive eruptions. Exsolution starts with nucleation and
growth of bubbles and fractures, and the permeability of the magmatic
foam evolves. These mechanisms lead to both
the outgassing and regassing of volatiles as magma encounters different
pressures and temperatures, prior to, during and after volcanic
eruptions.
Degassing mechanisms have been described in experiments, observed in
natural samples and geophysical signals and modeled. While new
techniques such as tomographic imaging and spectroscopic analysis allow
insights into microscopic scales of volatile pathways
and distributions, geophysical data and numerical models can help us to
understand the impact of such observations on the complex system of
processes of volcanic degassing during magma ascent. In this session we
invite contributions from all disciplines of
earth- and material sciences to one of the most fundamental aspects of
volcanic eruptions: magma degassing.
I am looking forward to meeting you in Vienna next year!
Cheers,
Felix
