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

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

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

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 ...

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.

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 ...

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 makes up more than 80% of the Earth’s mass, lying 6 miles (10 kilometers) beneath the ocean floor. “We don’t know the exact (composition) of the mantle yet. We have only seen some ...

Too deep to drill, the mantle's composition is a mystery leavened by two clues: meteorites, and hunks of rock heaved up by volcanoes. First, scientists think the composition of the Earth's mantle ...

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