When plumes of magma well up through Earth's lithosphere, they create volcanoes, islands, seamounts, and other features on ...

Scientists have known since the 1960s that mantle plumes stay in place for a very long time while the Earth's plates move ...

Lava that erupts from hotspots around the world seems to come from a similar ancestral magma, new research finds.

“At the East African rift zone, we have a present-day example of how a large hot upwelling mantle plume that originates at these deep mantle blobs (so aptly named LLSVP) starts to break up a ...

This posed a major puzzle. How could such ancient minerals exist on a relatively young volcanic island? Mechanics of the mantle plume under Easter Island. Credit: Douwe van Hinsbergen / Utrecht ...

An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.

A mysterious find on Easter Island, investigated by a team of geologists, suggests that the Earth's mantle seems to behave differently than once thought. Geography textbooks describe the Earth's ...

Geography textbooks describe the Earth's mantle beneath its plates as a well-mixed viscous rock that moves along with those plates like a conveyor belt. But that idea, first set out some 100 years ...
