Seismic images of Earth's interior reveal two massive anomalous zones at the base of the
mantle, above the core, where seismic waves travel slowly. The mantle materials that …

Plumes of hot upwelling rock rooted in the deep mantle have been proposed as a possible
origin of hotspot volcanoes, but this idea is the subject of vigorous debate,. On the basis of …

The periodic assembly and dispersal of supercontinents through the history of the Earth had
considerable impact on mantle dynamics and surface processes. Here we synthesize some …

Earth as an Evolving Planetary System, Fourth Edition discusses key topics dealing with the
evolution and interaction through time of Earth's crust, mantle, core, atmosphere …

Mantle plumes were conceived as thin, vertical conduits in which buoyant, hot rock from the
lowermost mantle rises to Earth's surface, manifesting as hotspot-type volcanism far from …

Large low shear velocity provinces (LLSVPs), whose origin and dynamic implication remain
enigmatic, dominate the lowermost mantle. For decades, seismologists have created …

Among the various university courses I took for my geoscience degree, volcanology and
structural geology motivated me by far the most. Volcanoes and deformed rocks are indeed …

Here we present the first radiometric age data and a comprehensive geochemical data set
(including major and trace element and Sr–Nd–Pb–Hf isotope ratios) for samples from the …

Based on SEMUCB‐WM1 tomographic model, validated by other recent models, and fluid
mechanics constraints, we show that the large low shear velocity provinces (LLSVPs) …

The radiogenic isotope heterogeneity of oceanic basalts is often assessed using 2D isotope
ratio diagrams. But because the underlying data are at least six dimensional (87Sr/86Sr …
