A tiny diamond contains tiny crystals of a new mineral. It makes up 5% of the lower mantle.

In diamonds pulled from deep within the Earth's surface, scientists have found the first example of a mineral never seen before.

Trapped inside a tiny diamond, there are tinier crystals of a never-before-seen mineral that makes up 5 per cent of the lower mantle.

Davemaoite is a vehicle for radioactive isotopes that help to heat the planet’s mantle.

The surprising find has never shown up in nature before and reveals secrets about the earth’s mantle.

The newfound mineral, dubbed davemaoite, only exists deep in Earth’s mantle.

Vincent Uhl of Uhl and Associates, based in Lambertville, N.J., will moderate a webinar of international hydrogeologists and water management officials focused on the Nile River Basin.

Scientists have discovered the world's deepest earthquake, which occurred 467 miles (751 kilometers) beneath the surface of the Earth.

An earthquake that struck at a whopping 751 kilometers (467 miles) below the Earth’s surface is the deepest ever recorded, scientists have revealed.

An earthquake that struck at a whopping 751 kilometers (467 miles) below the Earth’s surface is the deepest ever recorded, scientists have revealed. The tremor shook a zone thought to be impossible for quakes to occur in.

This depth places the earthquake in the lower mantle where seismologists thought it would be impossible to cause an earthquake.

In Japan, 751 kilometers deep. But experts can't explain exactly how this was possible.
