S401
Lithospheric structure, stress and deformation
Organiser: IASPEI
Lead Convener: Kevin Furlong (USA)
Co-Conveners: Ari Tryggvason (Sweden)
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.

S402
Orogenic systems
Organiser: IASPEI
Lead Convener: Kevin Furlong (USA)
Co-Conveners: Valerie Maupin (Norway)
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.

S501
Structures in the Mantle and Core
Organiser: IASPEI
Lead Convener: Thorne Lay (USA)
Co-Conveners: George R. Helffrich UK)
Invited Speaker: Vernon Cormier (U. Connecticut, USA)
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.

S502
Dynamical Processes in the Mantle and Core
Organiser: IASPEI
Lead Convener: Bernhard Steinberger (Germany)
Co-Conveners: James Wookey (UK)
Invited Speakers: Jessica Irving (U. Cambridge, UK), Trond Torsvik (U. 
Oslo, Norway)
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.

S503a:
Oceanic Spreading Centers
Lead convener: Donna Blackman (USA)
Co-conveners:Mathilde Cannat (France), Bryndis Brandsdottir (Iceland), 
Ari Tryggvason (Sweden)
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
  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.

S503b:
Subduction systems
Lead convener: Shamita Das (UK)
Co-convener: Satish Singh (France)
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.

S503c:
Plate boundary processes: Diffuse plate boundaries
Lead convener: Gregory Houseman (UK)
Co-conveners: Richard Gordon (USA), Tim Stern (New Zealand), Lucy Flesch 
(USA)
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.
