[CIG-ALL] AGU session S030 "Recent Advances in Interpretations of Tomographic Images”

[Lorenzo Colli]

Dear colleagues,

We invite you to submit an abstract to our AGU session S030 "Recent
Advances in Interpretations of Tomographic Images” for the upcoming AGU2019
Fall meeting in San Francisco:

Session description:
Tomographic images of (an-)elastic heterogeneity are a fundamental tool for
the study of the Earth's interior. However, interpretation of such images
is hindered by the finite resolving power of tomography and by non-linear
relations between elastic parameters and other quantities of interest, such
as composition, density and temperature. These relationships are not only
influenced by the material properties of single minerals, but also by
changes of the phase assemblage as a function of pressure and temperature.
Furthermore, the anelastic nature of minerals adds to the difficulty of
interpreting seismic models, as the parameters controlling the associated
increase in temperature sensitivity of the velocities are not
well-constrained.
This session provides a platform to present advances in constraining
interpretations of seismic tomography. Of general interest are
quantifications of uncertainties, tests of interpretations against
independent datasets, theoretical results from geodynamic modelling and
mineralogical studies constraining the relationship between temperature and
seismic velocity.
