We would like to draw your attention and invite you to contribute to the
Session \" The geochemical evolution of the mantle: From Hadean to modern
signatures\" at the 1st European Mineralogical Conference 2012 (September 2-6
A keynote talk will be given by Tim Elliott (Bristol) about \"Tracing mantle
evolution with novel isotopic systems\".
Abstract Deadline is May 15th, 2012

Session 1b: The geochemical evolution of the mantle: From Hadean to modern
Convenors: Dmitri Ionov (Saint Etienne, France), Stefan Weyer (Hannover,
The Earth\'s mantle has experienced multiple modifications during its 4.5
billion year history of dynamic evolution. Geochemical depletion occurs
mainly in the upper mantle during partial melting events linked to the
formation of oceanic and continental crust. Enrichment is mainly associated
with recycling of crustal materials to the mantle via subduction and related
mantle upwelling. Fluids likely play a key role to trigger these processes.
In the last decade, several new geochemical proxies have been developed to
study mantle processes, including \"non-traditional\" stable isotope and
radiogenic isotope systems (long- or short-lived) that can now be analyzed
with very high precision. With this session we want to invite contributions,
which improve our understanding of modern and ancient mantle dynamics, and
enable to fingerprint mantle reservoirs that formed during the whole history
of the Earth.
We are looking forward to seeing you in Frankfurt,
Dmitri Ionov, Stefan Weyer
