New simulations reveal that an ancient ocean of magma located above the Earth's core continues to shape the planet's ...

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...

They reveal that the chemical composition of the deep mantle has remained almost intact since the Earth's formation 4.5 ...

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.

Simulating the deep Earth . Where the core meets the mantle, liquid iron rubs up against solid rock. That's as dramatic a transition as the rock-to-air interface at Earth's surface, Shim told Live ...

A cutaway section shows the Earth's interior. The mantle and crust have long been thought to move together, much like a conveyor belt, but new evidence suggests the mantle's behavior may be far ...

Geologists Uncover Remnants of Earth’s Mantle That Have Lasted Over 2.5 Billion Years New research suggests that a discrepancy in rocks shows they endured extreme heat, and reveals more about an ...

Geoscientists have made an unprecedented achievement on their 60-year quest to know more about Earth's mysterious depths. Pieces of Earth’s rocky mantle were collected by a drilling vessel ...

Another example of Earth's mantle heterogeneity is two anomalous regions—called Large Low Velocity Provinces (LLVPs)—that stretch for thousands of kilometers at the base of the mantle.

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 ...

Longest rocks ever recovered from Earth’s mantle. The 4,160-feet-long sediment core could help scientists learn about magma, volcanoes, and more. By Laura Baisas.

The relative abundance of HSEs in the mantle points to delivery via impact after Earth’s core had formed; however, retaining those elements in the mantle proved difficult to model — until now.
