Thread: IUGG2019 - S16 session: Structure and Dynamics of the Extended Transition Zone - call for abstracts

Dear Colleagues,



The IUGG is holding its centennial Assembly this year: July 8-18 2019 in Montreal, Canada.

Abstract and travel grant submission deadline is: February 18th, 2019 ;

at: http://iugg2019montreal.com/abstract-submission.html



Please consider submitting an abstract to the session:

----------

S16 - STRUCTURE AND DYNAMICS OF THE EXTENDED TRANSITION ZONE (400-1000 KM) AND MID MANTLE (IASPEI):

-----------

The separation between the upper and the lower mantle has traditionally been placed at the 660 km discontinuity, which is a well-documented phase change in the olivine system, and the last one of its kind down to D” depths. Yet, there is mounting evidence from seismic tomography that the character of mantle dynamics changes around 1000 km depth, resulting in the notion of an “extended transition zone” (ETZ) that may be critical for understanding of how plate tectonics works. This symposium invites contributions from seismic imaging, geodynamics modeling and mineral physics that provide insights on the structure of the ETZ, including the phase transitions at 400 and 660 km as well as the nature and role of the emerging fuzzy boundary at 1000 km depth.
