GyPSuM: A joint tomographic model of mantle density and seismic wave speeds
GyPSuM is a 3‐D model of mantle shear wave (S) speeds, compressional wave (P) speeds,
and density. The model is developed through simultaneous inversion of seismic body wave …

Cluster analysis of global lower mantle tomography: A new class of structure and implications for chemical heterogeneity
Earth's lower mantle is dominated by a pair of antipodal large low shear velocity provinces
(LLSVPs) that reach> 1000km up from the core–mantle boundary (CMB). These are …

Tidal tomography constrains Earth's deep-mantle buoyancy
Earth's body tide—also known as the solid Earth tide, the displacement of the solid Earth's
surface caused by gravitational forces from the Moon and the Sun—is sensitive to the …

2.16 Seismic anisotropy of the deep Earth from a mineral and rock physics perspective
D Mainprice - Treatise on geophysics, 2010 - books.google.com
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 …

Reconciling dynamic and seismic models of Earth's lower mantle: The dominant role of thermal heterogeneity
Two large low-shear-velocity provinces (LLSVPs) in the deep mantle beneath Africa and the
Pacific are generally interpreted as hot but chemically dense 'piles', which have remained …

SP12RTS: a degree-12 model of shear-and compressional-wave velocity for Earth's mantle
We present the new model SP12RTS of isotropic shear-wave (VS) and compressional-wave
(VP) velocity variations in the Earth's mantle. SP12RTS is derived using the same methods …
