[Antoine Triantafyllou]

Dear Colleagues,

Happy new year ! We would like to draw your attention to the following
session
*Growth, accretion, structure and preservation of oceanic and continental
ARCS: from fossil records to active settings  (T6.7/GMPV5.13)*
at the next EGU General Assembly in Vienna (17 - 22 April, 2016). The
abstract submission deadline is Wednesday January 13rd, 2016 @ 13:00 CET.

Invited speakers:
K. Vogt  (Utrechts University, Netherlands)
J. Tetreault (NGU - Geodynamics team, Norway)

Please, do not hesitate  to contact us. We are looking forward to
seeing you in Vienna !

Kind regards,


A. Triantafyllou, J. Berger, C. J. Garrido, D. Bosch, P. Bouilhol

Growth, accretion, structure and preservation of oceanic and continental
ARCS: from fossil records to active settings


Arcs are key-geological actors of plate tectonics. They are viewed as
major factories contributing to crust generation, continental growth,
explosive volcanism and the geochemical cycles through the solid
Earth, via magma production, differentiation and crustal foundering.
Few accreted arcs sections expose a complete crustal and upper mantle
section emphasizing the crucial role of arc preservation during
subduction and continental collision. Activearc settings, in turn,
allow direct investigation of the upper crustal and volcanic dynamics
while, apart for indirect imaging or discrete sampling (xenoliths),
very little is known about their deeper crustal section. Recent
studies and results acquired on fossil and active arc systems have
boosted our comprehension of subduction initiation, arc growth and
accretion as well as their ultimate participation in crust production.
The study of arc construction and accretion processes through Earth's
history - from Archean to modern case studies - requires bringing
together
multidisciplinary communities across a wide range of disciplines and
methods encompassing, among others, (i) igneous, structural,
petrological, geochemical, geochronological studies in exhumed arc
sections and active arcs, (ii) new insights from recent advances in
analogue and
numerical modeling, (iii), geophysical studies of active arcs, and
(iv) deep drilling of active oceanic arcs as such recently
accomplished by IODP expeditions in the western Pacific.

This session invites wide-ranging multidisciplinary contributions
aimed at constraining growth, structure, accretion and preservation
processes of oceanic and continental arcs; going from melting
processes in the sub-arc mantle, mass transfer in the subduction zone
and igneous, tectonic and metamorphic processes in the arc crust.
