Dear colleagues,
We would like to bring to your attention and encourage contributions to
the following special session in the upcoming Goldschmidt conference at
Prague, Czech Republic. The session description is given below -
04d: Influence of Volatiles on Mantle and Magma Processes
http://www.goldschmidt2011.org/themes?theme=04&showDescriptions=true#session_04d
Volatile elements such as hydrogen, carbon, sulfur, chlorine, and
fluorine in the Earth's mantle play a key role in controlling the
dynamics and differentiation of the planet, as well as in facilitating
elemental exchange between the mantle and its exospheric reservoirs.
These elements, stored in various forms and concentrations, are known to
have significant effects on the loci of partial melting and on physical
and chemical properties of magma including viscosity, density,
conductivity, diffusivity, oxidation state and elemental compositions.
The presence of hydrogen is also known to influence the physical
properties of minerals; whereas the presence of volatile-bearing partial
melts likely have considerable influence on convective processes in the
mantle. This session seeks to highlight recent advances in geochemical,
geophysical, and petrologic constraints on the involvement of volatiles
on mantle processes including melting, element fractionation, redox
reactions, mantle flow, and element transport. We encourage
contributions from any discipline, that cover some aspect of volatile
cycling in the Earth's interior based on: (1) natural observations of
lavas, xenoliths, melt inclusions or fluids, (2) laboratory experiments,
and (3) theoretical calculations and geodynamic modeling.
