Dear colleague,

We would like to draw your attention to the following session at
EGU Vienna, 2010, May 2-7th.

Geomorphology Session GM5.3 "Interpreting the detrital record: advances,
applications, and limitations".

Invited talks by: Sebastien Castelltort (ETH Zurich); Eduardo Garzanti 
(Milan) & Randy Parrish (NIGL, UK)

The detrital record is a vast archive of material that has been removed
from the surface of the Earth over time. This record can be used to
provide insights into the generation and evolution of continental crust
in a variety of constructive and destructive plate tectonic settings. In
regions of mountain building the detrital record can inform about the
thermal and tectonic evolution of orogens, while in subduction-related
environments sediment flux can affect plate growth.

In recent years the number of studies using single-grain age dating and
isotope geochemistry techniques on detrital sediments has increased,
particularly with a focus on zircon. This is a direct response to an
increasing impetus to improve temporal constraints on factors that
govern crustal evolution and the rates at which surface processes
operate. There is a general acceptance that the sediment archive is an
accurate reflection of the material that has been removed from the
surface. However, recent studies have suggested that there is a bias in
preservation - due to plate setting or low temperature alteration - that
can dramatically alter how we interpret the detrital record. As the
number of studies increases, awareness of potential limitations needs to
improve.

We actively encourage contributions that investigate aspects of the
detrital record from crustal growth and orogenesis through to
preservation and phase alteration. Especially encouraged are
multidisciplinary approaches that incorporate geochronology, petrology
and isotope studies.
