The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the ...

Unsustainable irrigation and drought have emptied nearly all of the Aral Sea’s water since the 1960s, causing changes extending all the way down to Earth’s upper mantle, the layer beneath the planet’s ...

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, ...

A new study from a University of Chicago scientist suggests there may be a layer of surprisingly fluid rock ringing the Earth, at the very bottom of the upper mantle. The finding was made by measuring ...

South of India, the ocean surface slumps into one of Earth’s strangest depressions, a gravity hole so deep it has puzzled ...

The mechanical behaviour of Earth’s upper mantle is governed by the deformation of peridotite, dominated by the mineral olivine, under high‐temperature and high‐pressure conditions. Deformation ...

The transition zone between the Earth's upper and lower mantle contains considerable quantities of water, according to an international study involving the Institute for Geosciences at Goethe ...
