Japan Geoscience Union 2015. S-VC11 Volatiles and volcanoes
*****************************************************************************************************
Dear Colleagues,
We would like to draw your attention to the following International session at JpGU 2015 in Chiba, Japan (24 – 28 May, 2015):
S-VC11 – Volatiles and volcanoes: the role of volatiles in determining how and when volcanoes erupt
Conveners: Iona McIntosh (JAMSTEC, Japan), Atsushi Toramaru (Kyushu University, Japan), Alexander Nichols (JAMSTEC, Japan)
Description: The volatile content of magma is a key factor in determining the eruption style of a volcano. Dissolved volatiles such as H2O, CO2, S and F etc. affect melt viscosity and other physical properties, while volatile exsolution further modifies magma rheology and drives magma ascent via the nucleation and growth of bubbles. Volatiles, melt viscosity and bubble growth dynamics are thus interdependent parameters that directly affect physical eruption mechanisms such as style and depth of magma fragmentation. This session will explore the relationship between volatiles and magmatic processes, from source to surface and micro- to macro-scale, by examining how magmatic volatile contents, physical controls on volatile exsolution, dynamics of bubble growth, development of degassing pathways, and surface gas emissions relate to physical eruption mechanisms, and what evidence for these can be found in eruption products and geophysical and geochemical observational records. We encourage submissions from a broad range of approaches, including geochemical analyses, experimental studies, numerical modelling and field observations, and particularly encourage presentations of new investigative techniques.
** Upcoming deadlines: Advance abstract submission ends 3rd February; Final abstract submission ends 18th February **
Our session is one of several international sessions, where both oral and poster presentations are given in English, and one of several volcanology sessions. A list of international sessions can be found here: http://www.jpgu.org/meeting_e/international.html, while the full list including Japanese-language sessions can be found here: http://www.jpgu.org/meeting_e/session_list/index.htm.
JpGU 2015 will be held in Chiba city, Japan. Ideally located less than 40 minutes from both central Tokyo and Narita International Airport, Chiba (the ‘town of flowers’) also serves as a gateway to the beautiful Boso peninsula. Meeting details can be found on the conference website: http://www.jpgu.org/meeting_e/index.htm.
We look forward to seeing you in Japan!
Best wishes,
Iona
