*************************************************************** From: Shaul Hurwitz <shaulh@xxxxxxxx> *************************************************************** Dear colleagues, We would like to draw your attention to the following session that will be convened at the 2008 IAVCEI General Assembly in Reykjavik, Iceland, 18-22 August, 2008. The abstract submission deadline is 1 April 2008. Further information can be found at http://www.iavcei2008.hi.is/page/I08-intro 3-f The transport and interactions of aqueous fluids and gases in magmatic-hydrothermal systems Hydrothermal systems are zones where significant heat and mass transfer between magma and the ground-surface take place. These processes involve aqueous-rich fluids and gases ranging from supercritical brines and low-salinity vapors, to meteoric waters and seawater. These complex and dynamic systems are characterized by highly transient and heterogeneous temperature and pressure conditions and a wide range of chemical compositions. Quantification of processes and rates in these systems has implications for the thermal and chemical balance of the Earth's crust, volcanic hazards, geothermal exploration, formation of mineral deposits, and the flux of trace elements into the oceans. This session will focus on: - Modes and rates of heat and mass transfer from magma to the shallow subsurface - Spatial and temporal patterns in volcano magmatic-hydrothermal systems - The coupling between fluid flow, heat and mass transfer and related geophysical signals - The relationship between hydrothermal flow and volcanic eruptions - The relationship between hydrothermal flow and associated mineral deposits - Quantitative results derived from mathematical models, laboratory experiments, remote sensing, time-series analysis, in-situ measurements, geophysics, and geochemistry - Review papers integrating multi-parameters analyses of magmatic-hydrothermal systems - Submarine magmatic-hydrothermal Systems Conveners: Shaul Hurwitz - U.S. Geological Survey, Menlo Park, CA USA shaulh@xxxxxxxx Giovanni Chiodini - Osservatorio Vesuviano, Naples, Italy, chiod@xxxxxxxxxx Cornel E.J. de Ronde - GNS Science, Lower Hutt, New Zealand, Cornel.deRonde@xxxxxxxxxx Jo Gottsmann - University of Bristol, UK, j.gottsmann@xxxxxxxxxxxxx Guðni Axelson, Iceland GeoSurvey (ÍSOR), Reykjavík, Iceland gax@xxxxxxx ============================================================== 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. ==============================================================
