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



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



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.
