Dear colleagues,
We would like to invite you to submit an abstract to our session entitled:
“The architecture of volcanic plumbing systems: mush systems and beyond”,
which is within the Scientific Symposia called: “Using field data,
geophysics, geochemistry, statistics, and modeling to probe volcanic and
plutonic systems”.
The deadline for submitting the abstract at the next IAVCEI Scientific
Assembly
(Rotorua, New Zealand, Jan 30 to Feb 3, 2023) is September 2nd 2022
Session description:
In the last few decades, we progressively modified our vision of volcanic
plumbing systems moving form long-lived, melt dominated, shallow magma
chambers working at thermodynamic equilibrium to complex dynamical
reservoirs, mainly formed by crystal mushes, where liquid dominated regions
(i.e., eruptible magmas) ephemerally develop, in non-equilibrium
conditions, from deep to shallow-crustal levels. Here, eruptions are
triggered by a complex cascade of events involving many processes that are
often non-linear and that work at different spatial and temporal scales.
However, the focus on magmatic mushes within transcrustal differentiation
columns has, in part, distracted from the processes involved in transport
and eruption of crystal poor magmas of mafic to intermediate compositions,
which do not originate in mush zones but dominate the magma budget of
Earth. As in the felsic regime, mafic eruptions may be triggered through
spatially and temporally non-linear processes. To capture and describe the
evolution of eruptible magmas, we develop and employ methods involving a
range of disciplines, including geochemistry, petrology, volcanology,
geophysics, computational modeling, and mathematics. Combining these
approaches, we attempt to answer the main questions associated with the
study of volcanic plumbing systems. How does the melt phase evolve in space
and time? How do magmas move, through percolation or fracture propagation?
What are the rates of magma ascent? How do magmatic volatiles drive magma
ascent, and to what degree do they influence eruptive styles? And finally,
what are the timescales of pre-eruptive events? We welcome studies aimed at
understanding the architecture and the evolution of the volcanic plumbing
systems, in mush systems and beyond, from the widest spectrum of geological
settings.
