Elastic anisotropy of D ″predicted from global models of mantle flow
In order to test the hypothesis that seismic anisotropy in the lowermost mantle is caused by
the development of a post‐perovskite lattice preferred orientation, and that anisotropy can …

Mantle flow deflected by interactions between subducted slabs and cratonic keels
Oceanic lithosphere is rapidly recycled into the mantle through subduction, an important part
of the dynamic evolution of the Earth. Cratonic continental lithosphere, however, can exist for …

Deformation in the lowermost mantle: From polycrystal plasticity to seismic anisotropy
In the deep earth, deformation occurs at many scales: large-scale convection produces
subduction of slabs and upwelling of plumes in the mantle. At the high temperature/high …
