Some more problems of geodynamics
This dissertation presents new theoretical methods that could contribute to constraining the deep Earth’s long-wavelength density structure. In Chapter 2 we present a numerically exact method for calculating the internal and external gravitational potential of aspherical and heterogeneous planets. …

Imaging Resolution of the 410-km and 660-km Discontinuities
The structure of seismic discontinuities at depths of about 410 km and 660 km provides important constraints on mantle convection as the associated mineral phase transformations in the transition zone are sensitive to thermal perturbations. Teleseismic P-to-S receiver functions have been widely …

Wavefront Healing and Tomographic Resolution of Mantle Plumes
To investigate seismic resolution of deep mantle plumes as well as the robustness of the anti-correlation between bulk sound speed and S wave speed imaged in the lowermost mantle, we use a Spectral Element Method (SEM) to simulate global seismic wave propagation in 3-D wavespeed models and measure …
