To organise symposia at quadrennial IUGG meetings and the intervening assemblies of the International Association for Seismology and Physics of the Earth’s Interior (IASPEI) and the International Association for Volcanology and Chemistry of the Earth’s Interior (IAVCEI).
Forthcoming joint symposia
For the 2011 IUGG General Assembly to be held in Melbourne, Australia, two joint IASPEI/IAVCEI symposia will run across the middle weekend of the meeting (Friday-Monday, 1-4 July), as follows:
Symposium J-V03/J-S04: Physics and Chemistry of Earth Materials and Implications for Earth Structure and Processes
This symposium is intended to provide a forum for presentation and discussion of research into the physico-chemical behaviour of geological materials with implications for the structure and evolution of the Earth's crust and upper mantle. Topics of current interest include elasticity and rheology; diffusion; electrical conductivity; oxidation state of the mantle; carbon in the mantle under varying P-T-redox conditions; partial melting in a heterogeneous mantle and melt extraction; metamorphic phase equilibria and dehydration of subducting slab; refertilization and melting of the mantle wedge; the distinctive properties of cratonic roots; water in nominally anhydrous minerals and its impact on elasticity and rheology. Contributions on these and other related topics are welcome.
Keynote speaker:
Tomoo Katsura (Bayreuth, Germany)
Invited speakers (confirmed so far - more to come):
Jörg Hermann (Australian National University)
Cin-Ty Lee (Rice University)
Shun-ichiro Karato (Yale Unversity)
Convenors:

Symposium J-S05/J-V04: The Davies Mantle: Reconciling Geophysical and Geochemical Perspectives
This symposium, reflecting on the career-long contribution of Geoff Davies, is intended to provide an interdisciplinary forum for discussion of geophysical and geochemical constraints on mantle structure, chemical composition and dynamical processes. The separation of basaltic melt from refractory harzburgitic residue generates heterogeneity that is resistant to re-homogenization during subsequent mantle convection. Seismic tomography suggests that wavespeed heterogeneity is concentrated in the upper and lowermost parts of the mantle. Geochemical studies provide evidence of long-lived heterogeneity at various spatial scales. Numerical modelling of mantle convection favours at least episodic whole-mantle convection over the strictly layered alternative. Other topical issues include chemically equilibrated compositional models versus mechanical mixtures of components of contrasting chemical composition; melting of eclogite-pyroxenite lenses in a harzburgite mantle; the seismological observability of mantle plumes; the influence of pressure-induced electronic spin-pairing on wavespeed-depth gradients in the lower mantle; and the survival of heterogeneity in a vigorously convecting mantle.
Keynote speakers:
