*********************************************************************************** From: Hugh Tuffen [http://www.es.lancs.ac.uk/people/hught/hugh.html] *********************************************************************************** Dear All, Many thanks to all of you who have already submitted abstracts to the IAVCEI 2008 session 1-k "Chambers and conduits I: Geophysical, geochemical and geological observations". If you are yet to submit an abstract to this session please note that the submission deadline is 1st April. This session is dedicated to understanding the characteristics and dynamics of magma chambers, the magma conduits to the Earth's surface and volcanic vents, based on geophysical, geochemical and geological data and observations. http://www.iavcei2008.hi.is/page/I08-SYM1#1-k This session will focus on: - Imaging magma chambers and conduits using geophysical and remote sensing data sets and understanding their behaviour. - Understanding the time-scales of magma chamber formation, evolution, longevity, recharge, and closed system versus open system state. - Using geochemical approaches to constrain the timescale and mechanism of degassing and flow in shallow conduits - Understanding the role of geochemical processes in triggering eruptions (e.g. differentiation, fractionation, volatile behaviour, magma mixing) - Using geological studies of ancient magma chambers, magma conduits and vents to understand how magma chambers form and evolve, the processes of magma conduit formation and propagation, and the processes of vent formation and evolution. Case studies of all magma system types from ultrabasic komatiites and kimberlites, to basaltic, intermediate and silicic magma systems, and involving non-eruptive to effusive lava forming eruptions to explosive eruption systems, and a spectrum of volcano types will be welcome. Approaches that employ a combination of geophysical, geochemical and geological approaches are particularly encouraged. To submit an abstract (max. 350 words) visit the following website: http://www.iavcei2008.hi.is/page/I08-absub Conference homepage http://www.iavcei2008.hi.is/page/I08-intro We hope to see you in Reykjavik, it's shaping up to be a great session and a great conference! -------------------------------------------------------------------------------------------------- Ray Cas, School of Geosciences, Monash University, ray.cas@xxxxxxxxxxxxxxxxx Freysteinn Sigmundsson, Nordic Volcanological Center, Institute of Earth Sciences, University of Iceland, fs@xxxxx Hugh Tuffen,Department of Environmental Science, Lancaster University, h.tuffen@xxxxxxxxxxxxxxx ------------------------------------------------------------------------------------------------ ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
