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 ...

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 ...

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, ...

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 ...

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 ...

Geoscientists have made an unprecedented achievement on their 60-year quest to know more about Earth's mysterious depths. Pieces of Earth’s rocky mantle were collected by a drilling vessel called the ...

Seismic mapping of North America has revealed that an ancient slab of crust buried beneath the Midwest is causing the crust above it to "drip" and suck down rocks from across the continent. When you ...

In Geology 101, Earth's interior is divided into neat layers, like a sugar-coated jawbreaker. But it turns out that parts of the planet's middle layer might be more like peanuts in a sea of caramel.

Researchers have combined numerical modeling of dislocation glide and results from diffusion experiments to revisit the rheology of wadsleyite, ringwoodite and majorite garnet under geological strain ...
