*****************************************************************************************************
Dear Colleagues,
We would like to draw your attention to the Goldschmidt Session 17d:
Volatiles, Redox State, and Partial Melts in the Asthenosphere Down to the
Transition Zone
Keynote: Dan Frost (BGI, Germany)
Invited Speakers (to be completed soon): Mike Walter (Bristol, UK)
17d: Volatiles, Redox State, and Partial Melts in the Asthenosphere Down
to the Transition Zone
Convenors: Fabrice Gaillard (Univ. Orléans, France), Arno Rohrbach (Univ.
Munster, Germany), Sebastian Tappe (DeBeers Group, Witswatersrand, S-A)
In brief: We will discuss the complex interplays between redox state,
volatiles (contents, compositions, speciations) and the P-T conditions of
melting in the deep upper mantle. Whether melting is locally restricted or
rather widespread in the convecting upper mantle has profound geodynamic
implications. We invite petrological and geochemical studies on
deep-seated magmatic rocks (continental and oceanic), as well as
experimental and numerical simulations of melting processes generating
these magmas. Integrations with geophysical datasets and discussions on
the secular evolution of the volatile cycling and redox state of the
Earth's mantle are also welcome.
Deadline to submit @(http://goldschmidt.info/2015/abstracts) is April 2nd.
We look forward to seeing you in Prague, a beautiful and historical city.
Fabrice Gaillard
