New insight into the temperature of deep Earth

Scientists from the Magma and Volcanoes Laboratory (CNRS) and the European Synchrotron, the ESRF, have recreated the extreme conditions 600 to 2900 km below the Earth's surface to investigate the melting of basalt in the ...

Plate tectonics thanks to plumes?

"Knowing what a chicken looks like and what all the chickens before it looked like doesn't help us to understand the egg," says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to address plate tectonics and ...

Why do the Caribbean Islands arc?

(Phys.org) -- The Caribbean islands have been pushed east over the last 50 million years, driven by the movement of the Earth's viscous mantle against the more rooted South American continent, reveals new research by geophysicists ...

When the Earth mantle finds its core

The Earth's mantle and its core mix at a distance of 2900 km under our feet in a mysterious zone. A team of geophysicists has just verified that the partial fusion of the mantle is possible in this area when the temperature ...

Turbulence around heat transport

(PhysOrg.com) -- Heat transport in the earth's mantle and in the atmosphere is probably not as effective as previously thought.

Earth's mantle: New numerical tool describes rock deformation

Although solid, the rocks of the Earth's mantle deform very slowly. Professor Patrick Cordier's team at the Materials and Transformation Unit (Université Lille, France) has developed a model that makes it possible, over ...
