Theoretical Mantle Dynamics [PDF]
, 2018 Geodynamics is the study of the deformation and flow of the solid Earth and other planetary interiors. Focusing on the Earth's mantle, this book provides a comprehensive, mathematically advanced treatment of the continuum mechanics of mantle processes and the craft of formulating geodynamical models to approximate them.

Eos, Transactions American Geophysical Union, 1985 On November 20 and 21, 1984, the Geophysical Laboratory and the Department of Terrestrial Magnetism of the Carnegie Institution sponsored a workshop on the structure and dynamics of the mantle. The participants represented several academic institutions and a wide range of disciplines within the earth and planetary sciences.

Global observations of reflectors in the mid-mantle with implications for mantle structure and dynamics [PDF]
Nature Communications, 2018 AbstractSeismic tomography indicates that flow is commonly deflected in the mid-mantle. However, without a candidate mineral phase change, causative mechanisms remain controversial. Deflection of flow has been linked to radial changes in viscosity and/or composition, but a lack of global observations precludes comprehensive tests by seismically ...

Mantle flow through a tear in the Nazca slab inferred from shear wave splitting
Geophysical Research Letters, 2017 A tear in the subducting Nazca slab is located between the end of the Pampean flat slab and normally subducting oceanic lithosphere. Tomographic studies suggest mantle material flows through this opening.

Multi‐Layer Seismic Anisotropy Beneath Greenland
Geochemistry, Geophysics, Geosystems, 2021 Seismic anisotropy provides insight into past episodes of lithospheric deformation and the orientations of strain in the underlying asthenosphere. The Greenland mantle has played host to a rich history of tectonic processes, including multiple orogenies ...
