Much progress has been made over the past several decades in delineating the structure of
subducting slabs, but several key aspects of their dynamics remain poorly constrained …

In order to constrain better the distribution, age, geochemistry and origin of widespread
Cenozoic intraplate volcanism on Zealandia, the New Zealand micro-continent, we report …

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 …

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 …

Closure of the Central American seaway was a local tectonic event with potentially global
biotic and environmental repercussions. We report geochronological (six U/Pb LA‐ICP‐MS …

The direction of tectonic plate motion at the Earth's surface and the flow field of the mantle
inferred from seismic anisotropy are well correlated globally, suggesting large-scale …

Increasingly, spatial geochemical zonation, present as geographically distinct, subparallel
trends, is observed along hotspot tracks, such as Hawaii and the Galapagos. The origin of …

Thin oceanic crust is formed by decompression melting of the upper mantle at mid-ocean
ridges, but the origin of the thick and buoyant continental crust is enigmatic. Juvenile …

We present the first regional surface velocity field for Central America, showing crustal
response to interaction of the Cocos and Caribbean plates. Elastic half‐space models for …

Recent studies indicate that mantle plumes, which transfer material and heat from the earth's
interior to its surface, represent multifaceted upwellings. The Tristan-Gough hotspot track …
