Scope
|
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.
