Dr. Straume and colleagues investigated the role of mantle convection to explain these changes by using present-day measurements from seismic tomography (imaging Earth's interior using seismic ...

The emerging model of mantle convection suggests that some relatively cool subducting slabs of oceanic plate (blue) are deflected at the 660 km discontinuity (dashed black line) whereas others ...

How plate tectonics works The driving force behind plate tectonics is convection in the mantle. Hot material near Earth's core rises, and colder mantle rock sinks. "It's kind of like a pot boiling ...

Cratons are fascinating yet enigmatic geological formations. Known to be relatively stable portions of the Earth's ...

An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.

The North China Craton (NCC) is a very old and stable geological structure, experiencing deformations since the Mesozoic era.

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.

Convection is the process that drives hot currents ... which can't sink into the Earth's dense mantle. For at least 80 million years the oceanic Indian Plate continued its inexorable collision ...

The mantle is split up into two domains — the African and the Pacific — that emerged when supercontinent Pangaea broke apart. When you purchase through links on our site, we may earn an ...

“This study provides a first present-day example of how a cold downwelling from above is breaking up a deep mantle blob,” says Sanne Cottaar, a professor of global seismology at the University ...
