S401<br>
Lithospheric structure, stress and deformation<br>
Organiser: IASPEI<br>
Lead Convener: Kevin Furlong (USA)<br>
Co-Conveners: Ari Tryggvason (Sweden)<br>
Description: This symposia will include research focusing on
imaging lithospheric structure, the nature of stress in the
lithosphere, and the resulting patterns of deformation. This
session invites contributions on topics including the range of
deformational processes within the lithosphere, the nature of the
boundaries within the lithosphere, the mapping of and conditions
at the base of the lithosphere, mechanical, chemical and physical
properties of oceanic and continental lithosphere, plate driving
forces and other stress generators for the lithosphere, and other
topics related to the generation, evolution and behavior of
lithosphere. Case (and field) studies, relevant experimental
results, and modeling investigations are all within the scope of
this symposium. A goal of this symposium is to bring together the
wide range of lithosphere science.<br>
<br>
S402<br>
Orogenic systems<br>
Organiser: IASPEI<br>
Lead Convener: Kevin Furlong (USA)<br>
Co-Conveners: Valerie Maupin (Norway)<br>
Description: Orogenic studies often focus on deformation within
the upper and middle crust, neglecting the role played by the
entire lithosphere in the scale, and style of deformation. Here we
wish to include the broad range of studies related to orogenic
systems ranging from crustal scale to full-lithosphere scale.
Contributions are invited to the symposium ranging from those
detailing focused studies of specific orogenic systems to modeling
and theoretical studies of lithospheric processes associated with
orogenesis. Both plate boundary systems (including subduction
processes) and intraplate orogenic systems are considered within
the scope of this session.<br>
<br>
S501<br>
Structures in the Mantle and Core<br>
Organiser: IASPEI<br>
Lead Convener: Thorne Lay (USA)<br>
Co-Conveners: George R. Helffrich UK)<br>
Invited Speaker: Vernon Cormier (U. Connecticut, USA)<br>
Description: Topics include tomography, imaging, and modeling of
fine-scale and large-scale structures in the upper mantle,
transition zone, lower mantle, outer core and inner core.
Mineralogical phase transitions, anisotropy, spin-transitions,
core snow, etc. related to deep Earth structure, and tests of
their presence and effects in the mantle are of interest.<br>
<br>
S502<br>
Dynamical Processes in the Mantle and Core<br>
Organiser: IASPEI<br>
Lead Convener: Bernhard Steinberger (Germany)<br>
Co-Conveners: James Wookey (UK)<br>
Invited Speakers: Jessica Irving (U. Cambridge, UK), Trond Torsvik
(U. Oslo, Norway)<br>
Description: Topics include modeling of boundary layer and large
scale dynamics of the core and mantle, including deep plate
subduction, asthenospheric processes, thermal plumes, inner core
dynamics, core-mantle boundary coupling. Both ancient and modern
day dynamical systems, as related to core and mantle evolution are
of interest, along with thermal evolution models for the core and
mantle.<br>
<br>
S503a:<br>
Oceanic Spreading Centers<br>
Lead convener: Donna Blackman (USA)<br>
Co-conveners:Mathilde Cannat (France), Bryndis Brandsdottir
(Iceland), Ari Tryggvason (Sweden)<br>
Description: Oceanic spreading centers are the locus of tectonic
and magmatic processes whose relative balance determines the
structure and crustal composition of a majority of Earths
lithosphere. Geophysical mapping, imaging, and modeling in recent
years provide significant advances in understanding the structure
of young oceanic lithosphere. Imprints of these early-age
tectonic, magmatic, and hydrothermal processes are an integral
part of global scale cycling upon ocean lithosphere subduction.
State-of-the-art geophysical imaging/processing sheds new light on
the distribution of magma within the axial zone and beneath nearby
flanks. Micro-seismicity can indicate some aspects of hydrothermal
activity. Employing constraints from recent geological
observations, numerical modeling and geophysical results have
begun to illuminate how different faulting styles can
develop/evolve and how this interacts with variation in magmatism
(supply and/or delivery patterns) and seawater circ<br>
ulation and associated alteration. This session aims to cover
mantle, crustal, and hydrothermal processes through a combination
of recent observational results and insights obtained by modeling
aspect(s) of the system.<br>
<br>
S503b:<br>
Subduction systems<br>
Lead convener: Shamita Das (UK)<br>
Co-convener: Satish Singh (France)<br>
Description: With improved marine study techniques, we now know
that there are tens of thousands of seamounts all over oceanic
plates. When these seamounts are carried into subduction zones,
they influence the earthquake generation and rupturing processes,
the fault zone properties, the forearc morphology, and the
geochemistry related to the subduction factory. In this session,
we solicit contributions on any topic related to subduction, with
a special focus on subduction of seamounts. The scope includes
topics ranging from marine geological to geophysical and
seismological to geochemical and modeling studies.<br>
<br>
S503c:<br>
Plate boundary processes: Diffuse plate boundaries<br>
Lead convener: Gregory Houseman (UK)<br>
Co-conveners: Richard Gordon (USA), Tim Stern (New Zealand), Lucy
Flesch (USA)<br>
Description: Diffuse plate boundaries cover a surprisingly large
percentage of the surface area of the Earth. Wherever continental
collision occurs, the deformation is distributed over a broad
zone. Increasingly there is evidence of diffuse deformation in
oceanic regions also. Diffuse deformation in the form of pervasive
shear, convergence or extension can affect the stability of the
lithosphere, which has produced important insights into the
evolution and dynamic state of continental lithosphere. Abstracts
on any aspect of diffuse plate boundaries, their structure and
evolution will be welcome.</font>
