Lithospheric layering in the North American craton
How cratons—extremely stable continental areas of the Earth's crust—formed and remained
largely unchanged for more than 2,500 million years is much debated. Recent studies of …

Azimuthal seismic anisotropy in the Earth's upper mantle and the thickness of tectonic plates
Azimuthal seismic anisotropy, the dependence of seismic wave speeds on propagation
azimuth, is largely due to fabrics within the Earth's crust and mantle, produced by …
