The boundary zone between Earth's molten metal core and the mantle, its rocky middle layer, might be a diamond factory. A new laboratory experiment finds that, under extreme temperatures and pressures ...

Researchers at Göttingen University have uncovered new evidence that some of Earth’s most precious metals began their journey far deeper than once thought. Working with volcanic rocks from ocean ...

Deep beneath our feet, far below the crust and mantle, Earth’s metallic heart is not as sealed off as geologists once assumed. New research indicates that gold and other precious metals are slowly ...

A recent study in Nature Communications by scientists from China and Belgium suggests that Mercury's core-mantle boundary (CMB) includes a diamond layer, potentially up to 18 kilometers thick, deep ...

If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, ...

The mantle has three to five times more carbon than researchers would expect based on the proportion of elements in stars and other planets. The diamonds found in this layer of Earth might explain the ...

Extreme chemical reactions could explain why Earth's middle layer has so much carbon. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The ...
