[Geodynamics] AGU session DI010: Heterogeneity in the Earth: Multi-disciplinary Perspectives from Imaging, Modeling, Geochemistry and Experiments

[Eva Bredow]

Dear Colleagues,


We would like to bring to your attention the following session at the 
next AGU 2019 Fall meeting in San Francisco. The deadline for abstract 
submission is Wednesday July 31st.


DI010: Heterogeneity in the Earth: Multi-disciplinary Perspectives from 
Imaging, Modeling, Geochemistry and Experiments

Studies of heterogeneity provide a critical record of potential 
geochemical reservoirs, long-term tectonic processes and current 
snapshots of the Earth’s deep interior. Recent progress in seismology, 
geochemistry, geodynamics, and mineral physics constrain heterogeneity 
across a range of spatial scales. Advancements in imaging with the full 
spectrum of seismic data have afforded multi-scale constraints on 
parameters like attenuation, anisotropy, and density. New geochemical 
data have refined our understanding of Earth accretion, differentiation, 
and the onset of plate tectonics. Experimental and computational studies 
of mineral physics have improved constraints on materials at extreme 
conditions, permitting advanced geodynamic reconstructions. 
Heterogeneity implies variation in intrinsic properties like 
temperature, composition, grain size, or crystal structure, effects that 
need to be deconvolved through observations, experiments and atomistic 
simulations. We invite submissions that employ novel analytical and 
visualization techniques to explore the nature of heterogeneities and 
their relation to surface observables at local, regional, and global scales.

Invited speakers: Sanne Cottaar (University of Cambridge), Charitra Jain 
(Durham University)
