Grain size of rocks in Earth's mantle affects tectonics

The planet is shaped by forces deep within its interior. These push the plates of the Earth's crust against each other, causing mountains and volcanoes to form along the collision zones. But when reconstructing what exactly ...

Traces of life in the Earth's deep mantle

The rapid development of fauna 540 million years ago has permanently changed the Earth—deep into its lower mantle. A team led by ETH researcher Andrea Giuliani found traces of this development in rocks from this zone.

Geological cold case may reveal critical minerals

Researchers on the hunt for why cold eclogites mysteriously disappeared from geological records during the early stages of the Earth's development may have found the answer, and with it clues that could help locate critical ...

Nature recycles trash to create diamonds

The Earth's deepest diamonds are commonly made up of former living organisms that have effectively been recycled more than 400 kilometers below the surface, new Curtin research has discovered.

A new, clearer insight into Earth's hidden crystals

Geologists have developed a new theory about the state of Earth billions of years ago after examining the very old rocks formed in the Earth's mantle below the continents.
