Earth’s lower mantle trapped far more early water than previously thought

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks move, melt, and recycle through the mantle. Some of that water carries a ...

New parameter enhances insights into the evolution of mantle’s redox states

Researchers proposed a “potential oxygen fugacity” parameter to directly compare the fO 2 characteristics of melts formed at different depths. The oxygen fugacity (fO 2) of the mantle controls the ...

Compositional evolution of the upper mantle driven by plate tectonics

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, ...
