A robust knowledge of seismic anisotropy beneath the continents is essential to our
understanding of plate tectonic theory, as anisotropy provides a unique constraint on the …

Elastic anisotropy is present where the speed of a seismic wave depends on its direction. In
Earth's mantle, elastic anisotropy is induced by minerals that are preferentially oriented in a …

An Introduction to Seismology, Earthquakes and Earth Structures is an introduction to
seismology and its role in the earth sciences, and is written for advanced undergraduate and …

Observations of seismic anisotropy yield some of the most direct constraints available on
both past and present-day deformation in the Earth's mantle. Insight into the character of …

Recent research in the Himalayan fold‐thrust belt provides two new sets of observations that
are crucial to understanding the evolution of the Himalayan‐Tibetan orogenic system. First …

For decades there has been a vigorous debate about the depth extent of continental roots,.
The analysis of heat-flow, mantle-xenolith and electrical-conductivity data all indicate that …

Previous studies of samples of subcontinental lithospheric mantle (SCLM) that underlay the
North China Craton (NCC) during the Paleozoic have documented the presence of thick …

Kimberlites can be viewed as time capsules in a global plate tectonic framework. Their
distribution illustrates clustering in time and space. Kimberlite ages span the assembly and …

Shear-wave splitting measurements are widely used to analyze orientations of anisotropy.
We compare two different shear-wave splitting techniques, which are generally assumed to …

Plate tectonic theory hinges on the concept of a relatively rigid lithosphere moving over a
weaker asthenosphere, yet the nature of the lithosphere–asthenosphere boundary remains …
