Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Geodynamic simulations also suggest that ancient slabs like the one found under the East Pacific Rise may interact with deep mantle structures called super plumes, rising columns of hot rock that ...

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.

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Indian scientists have uncovered the possible cause behind the Indian Ocean Geoid Low (IOGL), the lowest geoid anomaly on ...

Beneath the Indian Ocean lies a 106-meter gravity hole, caused by ancient mantle plumes and vanished oceans. Scientists trace ...

Scientists have revealed that two continent-size regions in Earth's deep mantle have distinctive histories and resulting chemical composition, in contrast to the common assumption they are the same.

and highlight their connections to the deep and upper mantle. Mantle dynamics drive the formation of ocean islands and seamounts in the interior of oceanic plates. Yet the mechanisms for ...
