Scientists Discover Two Massive Structures Deep Within Earth’s Mantle, Say It Could Be Remains of Ancient Planet For decades, ...

Geochemists suggest that Earth's upper mantle varies in composition over kilometer-sized pockets. New research by Brown University geochemists provides new insights on the scale at which Earth's ...

This sample, which is more than six times longer than the previous core of mantle rock, has given us a glimpse into the composition of this mostly inaccessible layer of the Earth. You can read ...

Seismic imaging has exposed two massive zones hidden deep in Earth’s mantle. These giant blobs, known as large low-velocity ...

Earth is made up of several layers. Layers based on chemical composition are the core, mantle and crust. According to mechanical properties, Earth's layers are the lithosphere, asthenosphere ...

Using sophisticated analytical techniques, they discovered that the composition of the mantle below the Azores is different than previously thought -suggesting that large parts of it contain ...

The oxygen fugacity (fO 2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived magmatic activity ...

The mantle, a zone between our planet’s thin ... a professor of structure and composition of Earth’s deep interior at Utrecht University. “There was no information about that,” Deuss ...

Scientists still disagree about the composition of the deep mantle. There are odd structures near the core-mantle boundary called large low-shear velocity provinces (LLVPs), where seismic waves ...

WASHINGTON, Aug 8 (Reuters) - Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed ...

This discovery was made by two independent teams and challenges the previous view that the mantle – which lies between the Martian crust and core – has a uniform composition and structure. The new ...

As well as offering new insights into mantle composition, the drill core gives us other glimpses into Earth's deep geology and the conditions that could have been involved in the origins of life.
