Dear colleagues,
We would like to encourage you to contribute to a session on rifted
margins that has been scheduled for the
33rd International Geological Congress, which will take place from 6 to
14 August 2008 in Oslo, Norway.
Our aim is to discuss all aspects related to rifting and passive margin
formation.
The abstract submission deadline is 29 February.
Further details on the session are given below. Please pass this on to
anyone else you think might be interested.
We are looking forward to seeing you in Oslo.
Our best regards,
Ritske Huismans, Nina Simon, Lars Ruepke, Yuri Podladchikov

STT-02 Structure and formation of rift basins and passive margins from
surface to depth: Observations and modelling
(Disciplinary Symposia, Structural Geology, Tectonics)
The formation of rifted continental margins by extension of continental
lithosphere
leading to seafloor spreading is a complex and still poorly understood
component
of the plate tectonic cycle. New observations and modelling allow us to
investigate
the underlying processes. Key questions that need to be resolved are
factors that
control the style of extension, the role of strain localisation and
strain partitioning
throughout the rift history, processes responsible for anomalous
vertical motions
during basin evolution such as phase changes or small scale convective
instability
of the mantle lithosphere, fundamental controls on the magmatic or
a-magmatic nature
of passive margins. For instance on volcanic margins the relative timing
of extension
and magmatism, the origin of excess magmatism during breakup, and its
role for
lithosphere rheology need further understanding. On magma-poor margins
it is still
unclear what controls the absence of magmatism. Also many rift basins
appear to be
characterized by anomalous subsidence patterns in the late syn-rift and
post rift history.
We encourage abstracts that offer new insights into large-scale crustal
and lithospheric
processes underlying rifting and passive margin formation as well as
smaller scale studies
of individual sedimentary basins, using constraints from observations
and modelling.
