Hadean mantle oxidation inferred from melting of peridotite under lower-mantle conditions
The early Earth’s mantle is believed to have been highly reducing when it formed from a magma ocean equilibrating with the core. Conversely, some...

Earth’s mantle composition revealed by mantle plumes
Mantle plumes originate at depths near the core−mantle boundary (~2,800 km). As such, they provide invaluable information about the composition of...
