Like a mosquito tunneling into the skin to get at the rich feast within, geologists poked a long, narrow drill into Earth's crust last year, pulling out a treasury of geological goodness. The result ...

Earth's core is rich with gold, and it's leaking out through the mantle and into the crust, new research has found. A new study of isotopes found in the volcanic rock that oozed out from deep under ...

The gold and platinum that came from giant space rocks should have sunk into Earth's core instead of rising to the crust. Scientists have now worked out how this happened — and it may explain some ...

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new study ...

Deep under the crust and mantle of our Earth lies its core. Earth’s core was formed during the Iron Catastrophe, a major geological event where Earth was heated to temperatures above iron’s melting ...

ANN ARBOR—Strange things happen in the lower reaches of our planet’s mantle, that plastic-like layer between Earth’s crust and core that flows under pressure, lifting or lowering features on the ...

Our Earth is structured sort of like an onion — it’s one layer after another. Starting from the top down, there’s the crust, which includes the surface you walk on; then farther down, the mantle, ...

Two massive blob-like structures deep in Earth’s mantle are revealing a bigger picture about geological phenomena like volcanoes and plate tectonics. One blob lies deep beneath the African continent, ...

Oceanic island hotspots — Hawaii and Iceland — are the final destinations of elemental isotopes from the beginnings of Earth, in concentrations found nowhere else on Earth’s crust. Until now, it was ...
