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

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

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 ...

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.

A recent studypublished in Naturepresents compelling evidence of ancient planetary material buried deep within Earth’s mantle ...

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 ...

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 ...

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 ...

The plumes are thought to feed the mantle beneath adjacent ocean ridges. This process results in thickened crust and ridge elevation to form ocean rises. The composition of mid-ocean ridge basalt ...

While it's unlikely the deep-buried treasure chest will ever be cracked open, scientists call the discovery significant.

Scientists have found minerals around its edges that match the composition of these glass beads. If the beads are truly ...

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 ...
