********************************************************************** From: Raymond Cas <Ray.Cas@xxxxxxxxxxxxxxxxx> ********************************************************************** Dear Colleagues, We invite everyone who is interested to submit abstracts for the following symposium at the 2008 IAVCEI General Assembly in Reykjavik, Iceland, 18-22 August, 2008. The abstract submission deadline is 1 April 2008. Further information about the conference and abstract submission process can be found at http://www.iavcei2008.hi.is/page/I08-intro. We look forward to a very stimulating, interdisciplinary symposium on this intriguing topic. 1-k CHAMBERS AND CONDUITS I: GEOPHYSICAL, GEOCHEMICAL AND GEOLOGICAL OBSERVATIONS Conveners: Ray Cas, School of Geosciences, Monash University, ray.cas@xxxxxxxxxxxxxxxxx Hugh Tuffen,Department of Environmental Science, Lancaster University, h.tuffen@xxxxxxxxxxxxxxx Freysteinn Sigmundsson, Nordic Volcanological Center, Institute of Earth Sciences, University of Iceland, fs@xxxxx 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. 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 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. ==============================================================
