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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust ...

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 ...

Researchers have found evidence that Earth's core is leaking gold and other precious metals, according to a new study. The vast majority (99.9%) of Earth's gold and other precious metals are hidden in ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

Scientists discover 'hidden structure' in Earth's core which could 'rewrite the textbooks' ...

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, ...
