******************************** From: Patrick Allard <patrick.allard@xxxxxx> ******************************** Dear Colleagues, we attract your attention and invite you to contribute to the Session GMPV 8 of the 2007 European Geosciences Union (EGU) General Assembly in Vienna (April 15- 20), that is described below and on the EGU website at: http://www.cosis.net/members/meetings/programme/view.php?m_id=40&p_id=240 Session GMPV 8: Volcanic and non-Volcanic Earth Degassing Conveners: G. Chiodini (INGV, Naples, Italy) and P. Allard (LPS, Saclay, France) Volatile exchange between the Earth interior and the superficial envelopes constitutes an important aspect of global geochemical cycles. Volatile species ranging from major gas components (H2O, CO2, S, halogens) to trace metals are emitted in variable quantities and proportions through magmatic and volcanic activity, but also during non-volcanic (e.g. metamorphic) processes. Their emissions occur under various forms (e.g. volcanic gas plumes, particulate matter, soil emanations, bubbling waters, etc.) and thus require widely different methods of investigation. This Session is aimed at making a standpoint in our knowledge of volcanic and non-volcanic Earth degassing in terms of local and global volatile budgets, volatile speciation and degassing processes, relationships with specific tectonic settings, comparison with other natural/anthropogenic sources, and environmental impacts. Contributions from specialists of these various research aspects are welcomed. Papers will be considered either for oral presentations of 15 minutes each or for a poster session. Note that the Abstract Deadline is January 15, 2007. Abstracts should be submitted through the EGU website at http://www.cosis.net/members/frame.php?url=meetings.copernicus.org/egu2007/ Yours sincerely, Giovanni Chiodini INGV Via Diocleziano, 328 80124 Napoli, Italy E-mail: chiod@xxxxxxxxxx Patrick Allard Groupe des Sciences de la Terre Laboratoire Pierre Sue, CNRS-CEA CE-Saclay, 91191 Gif/Yvette, France E-mail: patrick.allard@xxxxxx Patrick Allard Directeur de Recherche Groupe des Sciences de la Terre Laboratoire Pierre Sue, CNRS-CEA (UMR 9956) CE-Saclay, 91191 Gif/Yvette, France Phone: 0033-1 69 08 85 42/97 49 Fax: 0033-1 69 08 69 23 ============================================================== 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. ==============================================================
