Abstract submission for the AGU Fall meeting is now open. We invite
contributions to the following session:
V19: Dynamics of Gas Transport in Magma
Abstract:
Emission of juvenile gases is a feature of active volcanoes both during
eruption, and during periods of quiescence. Gas transport is driven by
buoyancy
and may be facilitated by the rise, growth, and coalescence of bubbles,
by the
flow of gas through bubble and/or fracture pathways which permeate the
magma, or
by some dynamic combination of the two. The nature of the journey that
the gas
takes, from exsolution to emission, exerts a fundamental control on the
observed
eruptive behaviour. Submissions are sought which consider any aspect of the
transport of gas through magma and the volcanic system in general.
Experimental,
numerical, or theoretical treatments of the development of permeability
in magma
are particularly welcome as are studies which link the mechanism of gas
transport to eruptive style. Priority will also be given to research which
exploits field observations and measurements of surface gas emissions to
elucidate subsurface gas transport processes.
