A description of the session is provided below.
VS009: Models and Products of Mafic Explosive Activity
Sponsoring Association: IAVCEI
Mafic magmas can erupt explosively after a broad range of physical
processes that, among those already identified, include: surface
bursting of buoyant gas bubble slugs, multifarious interaction of magma
with external water, overpressurization of cooled magma plugs, annular
gas flow, and fast foaming of volatile-saturated melt. However different
these processes may appear, they all reflect the fundamental properties
specific of mafic magmas, mainly low viscosity and fast internal
kinetics. A current challenge to volcanologists is to relate, possibly
in a predictive manner, the above physical processes to the
highly-variable eruptive styles observed and the products and hazards
they emanate. The aim of this session is to bring together scientists
with different approaches to the processes that underlie mafic explosive
activity. In particular, three fields of research seems to increasingly
converge on this topic: a renewed effort on the study of mafic
pyroclasts and pyroclastic deposits; multiparametric geophysical,
geochemical, and volcanological observation of ongoing activity; and
analytical, numerical, and experimental simulation of eruptive
processes. All the above (and other) specific aspects of mafic explosive
activity will be welcome to this interdisciplinary session, and we
specially encourage the submission of presentations showing integration
of different approaches.
