[Geodynamics] 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.
