      Dear colleagues and friends,

      we would like to draw your attention to our session at
        this year's AGU Fall Meeting in San Francisco (Dec 14-18, 2015):

        V038:
      Transport of
          Volatiles from Mantle to Surface: Insights on Diffusion,
          Exsolution and
          Migration of Fluids in Magmatic Environments from Natural
          Samples and
          Experiments

      Invited
          speakers:
      Iona M.
          McIntosh, JAMSTEC, Japan
      Kristina J.
          Walowski, University of Oregon, USA
      James D.
          Webster, American Museum of Natural History, NY, USA

      Session ID#:
          8051
      Session
          Description:
      The transfer of volatiles (H₂O, CO₂,
        Cl, S, F) between reservoirs within the mantle, subducted
        oceanic crust and
        continental crust 1) influences magmatic processes, 2) modifies
        trace element
        and isotope signatures and 3) may change redox conditions. The
        physical and
        chemical properties of magmas are significantly influenced by
        diffusion and
        exsolution of volatiles during their ascent from the upper
        mantle through the
        crust to the surface. For instance, magma degassing may initiate
        volcanic
        eruptions, modulates magma viscosity (especially along the
        conduit) and, thus,
        affects the eruptive style. This session seeks insights from
        natural and
        laboratory observations involving volatile transfer and
        degassing.
        Cross-disciplinary studies (e.g. petrology with geophysics
        and/or geochemistry)
        providing temporal constraints, and/or involving volatile
        solubility, fluid and
        melt composition, isotope signatures and redox conditions are
        especially
        welcome.
