That’s the conclusion from experiments on rocks typical of those in the mantle transition zone, a global buffer layer 410 to 660 kilometres beneath us that separates the upper from the lower mantle.

Scientists have discovered an unusually thick mantle transition zone beneath the Lesser Antilles. This discovery sheds new light on how oceanic plates sink into the Earth's mantle. Variations in ...

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. Seismic tomography studies (CT scan imaging of the Earth's ...

A research team utilized teleseismic double-difference tomography technology to uncover the morphological changes of the Pacific subducting slab in the mantle transition zone beneath Northeast China.

The transition zone's high water content has far-reaching consequences (Representational Image) Scientists have discovered a reservoir of water three times the volume of all the oceans beneath the ...
