A continental rift is a nascent plate boundary where the lithosphere is thinned by tectonic
activity. Some continental rifts undergo extension to the point that they generate a new …

The Main Ethiopian Rift is a key sector of the East African Rift System that connects the Afar
depression, at Red Sea–Gulf of Aden junction, with the Turkana depression and Kenya Rift …

The structure of upper crustal magma plumbing systems controls the distribution of
volcanism and influences tectonic processes. However, delineating the structure and …

The third edition of this widely acclaimed textbook provides a comprehensive introduction to
all aspects of global tectonics, and includes major revisions to reflect the most significant …

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 …

In this section the contribution of CPO to seismic anisotropy in the deep Earth with cases of
olivine and the role of melt is illustrated. The CPO in rocks of upper-mantle origin is now well …

Measurements of the splitting or birefringence of seismic shear waves that have passed
through the Earth's mantle yield constraints on the strength and geometry of elastic …

Although many continental rifts and passive margins are magmatic, some are not. This
observation prompted endmember views of the mechanisms driving continental rifting …

The evolution and characteristics of narrow continental rifting are illustrated in this paper
through a review of recent lithospheric-scale analog models of continental extension …

We investigate mantle plumes and associated flow beneath the lithosphere by imaging the
three-dimensional S-velocity structure beneath Arabia and East Africa. This image shows …
