The 205-mile-deep hidden mantle zone under the Caribbean could reshape our understanding of Earth's interior.

"It's wild to think that in some ways tectonic plates have a 'memory' and that affects the way the plates drive mantle convection and mix material back into the Earth," said Dr. Nick Harmon, formerly ...

New research reveals a surprising link between the ancient tectonic history of oceanic plates and their fate as they subduct into Earth’s mantle. Compositional anomalies, formed millions of years ago, ...
