Mantle Structure and Evolution: Combining Seismological and Geodynamical Constraints Across Scales (including Arne Richter Award for Outstanding ECS Lecture by Mathew Domeier)

Many mantle structures have recently been observed by seismologists including the lithosphere-asthenosphere boundary (LAB), a possible transition near ~1000 km depth, small scale heterogeneities in the transition zone and in the lowermost mantle (ULVZ, D"), plumes, stagnating slabs, mantle anisotropy... However their origin is still unclear and geodynamical modelling can help propose plausible scenarios. Furthermore, geodynamic models and tomographic images often investigate different physical parameters, and propose views of the mantle at separate scales. Combining information from both fields is therefore necessary to understand and link mantle processes across scales. We encourage every contribution that can feed the dialogue between seismologists and geodynamicists.

Sollicited speakers: Harriet C.P Lau (Harvard University), Manuele Faccenda (University of Padova)
