6-6-6-6-6-6-6-6-6-6-6-6-6 From: STEFANIA SICOLA <stefania.sicola@xxxxxxxxxxx> Dear colleagues, Please consider submitting your abstract to the following session for the COV 11 conference in Heraklion, (Crete) 23-27 May 2020 ( https://pcoconvin.eventsair.com/volcanoes11/) *The abstract submission deadline is January 25. * *SESSION*: *S2.4* - *Time-scales of magmatic and volcanic processes combining analytical, experimental and field observations* *Session Description:* A magmaâ??s journey is characterized by a variety of reactions and processes occurring at different timescales, which can be from seconds to hundreds of thousands of years depending on local conditions (e.g., X, T, P, fO2). Different processes may happen concurrently in the magma chamber (e.g., magma mixing, mingling, crustal assimilation, crystal formation, bubble nucleation) and/or during the ascent of magma toward the Earthâ??s surface (e.g., crystal growth/dissolution, volatile degassing and permeable outgassing, fragmentation), hence controlling the internal dynamics of a volcanic plumbing system, including mechanisms of magma genesis, storage and transfer conditions and eruption style. Furthermore, all of these processes influence the morphology of a deposit and the path of its emplacement depending on the time/temperature conditions. We want to dissect glasses, minerals, and melts, or their volatile emissions, in order to constrain the timescales and location of those magmatic processes and to define the driving parameters of any magmatic plumbing system as it evolves. This session welcomes contributions that employ analytical, numerical, experimental, geophysical, and field-based methods by volcanologists, geochemists, geochronologists, and petrologists addressing rates and timescales of volcanic and magmatic processes. Innovative and interdisciplinary studies are also encouraged in order to improve our knowledge of ever-evolving volcanic environments, crucial for volcanic hazard assessment and social support. Core connection between the proposed session and societal risk mitigation: The most critical parameter to determine when dealing with risk mitigation is time. Volcanic events can be measured in units of seconds up to hundreds of thousands of years depending on local conditions such that a knowledge of these timescales can be of tremendous benefit to both the issues of hazard assessment and response. This session aims at exploring timescales from pre-eruptive processes within a magma chamber to critical phenomena occurring at the time of eruption and leading finally to its subsequent course of emplacement. Hope to see you in Crete! 6-6-6-6-6-6-6-6-6-6-6-6-6 ============================================================== Volcano Listserv is a collaborative venture among Arizona State University (ASU), Portland State University (PSU), the Global Volcanism Program (GVP) of the Smithsonian Institution's National Museum of Natural History, and the International Association for Volcanology and Chemistry of the Earth's Interior (IAVCEI).
