A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth's core, by showing how it was able to ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...

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 ...
