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

https://agu.confex.com/agu/fm19/prelim.cgi/Session/79800

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.
