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

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

Massive mantle formations, called LLSVPs, have been found to be over a billion years old. These structures, sitting 3,000 km beneath the surface, slow seismic waves, indicating unique physical and ...

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 ...

Deeply hidden in Earth's mantle there are two huge "islands" the ... This way, seismologists will be able to make images of the interior of our planet, just like a hospital doctor can "see ...

It was a shock for researchers to see new images that depicted large slabs ... Their existence suggests that the Earth's mantle is more complex than previously believed. "With the new high ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an ...
