[iris-bulk] IUGG General Assembly Symposium JSS011 on Earth Structure and Geodynamics

[Thorne Lay]

The XXIV IUGG General Assembly will be held July 2-13, 2007 in Perugia, 
Italy. Full details are available at http://www.iugg2007perugia.it/. The 
abstract deadline is February 28, 2007.

We would like to call your attention to Symposium JSS011:  Earth 
Structure and Geodynamics. Sponsored by IASPEI in collaboration with: 
IAGA, IAG, IAVCEI, ILP, SEDI

Integrated theoretical, observational and experimental studies involving 
seismology, geodynamics and geomagnetism are essential for advances in 
understanding of the dynamics of our planet. Fundamental problems such 
as the driving mechanisms for plate tectonics, the fate of subducted 
slabs, the role of water in the transition zone, the existence and 
nature of any mantle plumes, the isolation of geochemical reservoirs in 
the mantle, the structure and processes in the lowermost mantle boundary 
layer, and the chemical and physical interactions between the core and 
mantle all require multidisciplinary approaches. These topics will all 
be addressed in this symposium.

Seismology provides constraints on the structure and amplitudes of 
heterogeneity in elastic properties and density and on elastic 
anisotropy using many imaging and modeling approaches. Geodynamics 
provides insights on the thermo-chemical nature of mantle convection, 
boundary layer behavior, interaction of flow with phase transitions, 
time evolution, and deformation processes using numerical modeling and 
laboratory experiments. These two fields interact closely, combined with 
constraints from mineral physics, geochemistry and geomagnetism to 
develop quantitative understanding of how the planet works. Both 
disciplinary and multidisciplinary papers drawing from these fields are 
invited for this symposium.
