Due to the radiative thermal conductivity of the mineral olivine, only oceanic plates over 60 million years old and ...

New research reveals that only the oldest and fastest-sinking oceanic plates can transport water deep into Earth’s mantle, ...

We propose that the transition-zone water-filter model can explain many geochemical observations while avoiding the major pitfalls of invoking isolated mantle reservoirs.

Thirsty crystals The deep Earth holds about the same amount of water as our oceans. That’s the conclusion from experiments on rocks typical of those in the mantle transition zone, a global ...

Entering the mantle transition zone beyond ~410 km depth with increasing pressure (P) and temperature (T), olivine transforms first into its high-P polymorph wadsleyite and at ~520 km into ...

The Earth's mantle transition zone contains water locked up in minerals — enough to rival the oceans on the surface of the planet.

They wanted to better understand what happens at the transition zone within the mantle, and how stagnant slabs might affect circulation.

The transition zone between the Earth's upper and lower mantle contains considerable quantities of water, according to an international study. The research team analyzed a rare diamond formed 660 ...

This transition zone influences the extent of whole mantle convection by controlling mass transfer between the upper and lower mantle.
