Mantle plumes are mysterious upwellings of molten rock believed to transmit heat from the core-mantle boundary to the Earth’s surface, far from the edges of tectonic plates.

To find evidence of this core-mantle interaction, Messling and his coauthors obtained some samples of Hawaiian volcanic rocks from the Smithsonian Institution in Washington, D.C. “Some were ...

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new ...

We can now also prove that huge volumes of super-heated mantle material — several hundreds of quadrillion metric tonnes of rock — originate at the core-mantle boundary and rise to the Earth ...
