The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic ...

A breakthrough study has provided the most detailed 3D look yet at the inner workings of the Tonga Subduction Zone, where ...

The mantle is incredibly difficult to study because it’s so deeply buried beneath the Earth’s crust, or outer skin. Now, scientists have drilled a 1,268m-deep core that reaches down into this ...

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

Others have suggested that the blobs are huge chunks of oceanic crust that were pushed into the mantle when one tectonic plate slipped under another — a process known as subduction. The crust ...

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

High-Resolution Anisotropic Tomography Reveals Mantle Flow Complexity and Slab-Plume Interactions, Redefining Subduction Zone ...
