These ancient buried "super-continents"—known to scientists as large low-seismic-velocity provinces (LLSVPs)—were found ...

This is a 3D view of the top 1,000 kilometers of the earth's mantle beneath the central Pacific showing the relationship between seismically-slow "plumes" and channels imaged in the study.

A hotspot that is now located in the Atlantic played a key role in forming the lakes, home to a fifth of the world's fresh ...

Scientists from Utrecht University have discovered two enormous structures deep in Earth's mantle, suggesting that these ...

Deeply hidden in Earth's mantle there are two huge "islands" the size of a continent. New research from Utrecht University ...

Schematic representation of the process of subduction of tectonic plates and of a mantle plume rising from an LLSVP. In the latter, the mineral grains are larger than those in the subducted plates.
