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

Recent research by several teams has shown that that mantle has a layer that no one knew about—and its flow patterns are much more complex than would be expected in that part of the planet.

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 ...

Conducted by researchers from Ocean University of China and Tohoku University, Japan, the work combines innovative seismic methodologies to map mantle flow patterns, slab-plume interactions ...
