Rhythmic pulses of molten rock are rising beneath eastern Africa, according to a new study.The pulsing plume of hot mantle beneath Ethiopia, driven by plate tectonics, is slowly pulling the region ...

What is the chemical composition of the Earth’s interior? Because it is impossible to drill more than about ten kilometres deep into the Earth, volcanic rocks formed by melting Earth’s deep ...

The vertical movement of the mantle is one of the driving forces that brings about large-scale geological changes to the ...

A plume of molten rock deep beneath eastern Africa is pulsing upward in rhythmic surges, slowly splitting the continent and ...

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 ...

Rocky bodies called protoplanets were thought to have formed slightly earlier in the inner solar system than those beyond the ...

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

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied ...

A record-breaking 1268-meter drill core into Earth’s mantle, collected from the Mid-Atlantic Ridge in the North Atlantic, has provided a deep and detailed mineralogical glimpse of the ...

Water delivered to the mantle by aluminum enriched hydrated slabs? Velocities of aluminum enriched superhydrous phase B suggest the presence of hydrated mantle regions beneath subduction zones ...
