EGU 2012 Session Announcement
From: Ralf Gertisser <r.gertisser@xxxxxxxxxxxxxxxx>
*****************************************************************************************
Dear Colleagues,
We would
like to draw your attention to the following session at the EGU
General
Assembly (Vienna, Austria, 22-27 April
2012) and invite your contribution.
Symposium: GMPV – Geochemistry,
Mineralogy,
Petrology & Volcanology
Session: GMPV5.1: Magma generation
and
differentiation: Field, analytical, experimental and numerical
investigation of
magmatic and volcanic systems
This
session invites contributions targeting the generation and
differentiation of
magmas in the mantle and crust from field studies, petrology,
geochemistry
(major and trace elements and isotopes), experimental petrology
and
thermodynamic and geochemical modeling. Magma chemistry sampled
in plutonic and
volcanic rocks reflect combinations of processes operating in
their sources
(e.g. metasomatism by fluids and melts, asthenospheric-,
lithospheric- and
'exotic' mantle components such as pyroxenites as well as
crustal melting and
anatexis) and during differentiation from mantle depths to
shallow level magma
reservoirs and volcanic extrusions/explosions (e.g. fractional
crystallization,
assimilation, mixing/mingling, replenishment of magma reservoirs
and chambers).
The fundamental question to be addressed by this session is how
igneous systems
operate in different tectonic settings and what are the
principal controls on
primary, parental and derivative magma compositions.
Conveners:
Valentin R. Troll
(Uppsala
University, Sweden), Lilli Freda (INGV Rome, Italy) and Ralf
Gertisser (Keele
University, UK)
Abstract deadline is
17 January 2012.
