[iris-bulk] IUGG2007@Perugia on Deep Slabs

[KAWAKATSU, Hitoshi]

Dear Colleagues

We would like to draw your attention to the special session JSS012 at the
upcoming IUGG 2007 meeting in Perugia, titled "Dynamics of Deep Mantle
Slabs".

We solicit contributions from a wide variety disciplines of earth science
on related topics.

Deadlines for submission of abstracts :
Electronic submission of abstracts: February 28, 2007;

Invited Speakers (accepted):
Craig    BINA   (Northwestern University, USA)
Yoshio   FUKAO  (IFREE/JAMSTEC, JAPAN)
Kei      HIROSE (Tokyo Institute of Technology, JAPAN)
Fumiko   TAJIMA (Hiroshima University, JAPAN)
Pascal   TARITS (Univ. Bretagne Occidentale, FRANCE)
Rigobert TIBI   (Washington University, USA)



The official description of the session follows:

   Seismic tomography has revealed the presence of fast seismic velocity
anomalies, which are likely to be associated with the subducted oceanic
lithospheres, in and around the mantle transition zone of the current and
past subduction zones. Although the existence of such "stagnant slabs" is
now well established, their cause, fate and impact on the tectonics,
dynamics and evolution of the earth system are not well understood.
   We solicit contributions from a wide variety disciplines of earth
science to eventually answer questions like "Why do slabs stagnate, and
why/where do they disappear?”, "What occurs when they fall into the deep
mantle?". Contributions may include: detailed geophysical mapping of
subducted slab (including oceanic crust) signatures in the deep mantle,
dynamic modeling and high-pressure experiments to delineate the fate of
subducted slabs, possible connection between stagnant slabs and surface
tectonics and volcanisms, etc...
