Seismic tomography reveals 2 extensive regions in the lowermost mantle, beneath Africa
and the Pacific, that exhibit lower-than-average seismic wave speeds. These regions have …

A stagnant slab is a subducted slab of oceanic lithosphere subhorizontally deflected above,
across, or below the 660 km discontinuity. This phenomenon has now been widely …

Large numbers of earthquakes occur in subduction zones that are marked by dipping,
narrow high seismic velocity slabs. The existence of these fast velocity slabs can cause …

55 4.4 Experimental techniques 57 4.5 Some general trends in elasticity: Birch's law 59 4.6 …

Constraints on mantle temperatures are fundamental for a better understanding of the
dynamics of the Earth. We evaluate how well upper-mantle thermal structure can be inferred …

In the mantle underneath the Tethyan suture zone, large volumes of positive velocity
anomalies have been imaged by seismic tomography and interpreted as the present‐day …

Abstract Knowledge of the interior structure of Mars is of fundamental importance to the
understanding of its past and present state as well as its future evolution. The most …

Empirical finite strain theories, currently favored by various authors for geophysical use, are
critically reexamined. We focus attention on higher derivatives, especially K′= dK/dP (P is …

We present BurnMan, an open‐source mineral physics toolbox to determine elastic
properties for specified compositions in the lower mantle by solving an Equation of State …

The lowermost (> 2400km) Earth's mantle mapped by seismic tomography is strongly
heterogeneous, the most striking feature being two large regions where shear-wave velocity …
