Enhanced views of Earth tectonics

Scientists from Germany's Kiel University and British Antarctic Survey (BAS) have used data from the European Space Agency (ESA), Gravity field and steady-state Ocean Circulation Explorer (GOCE) mission to unveil key geological ...

Flow in the asthenosphere drags tectonic plates along

New simulations of Earth's asthenosphere find that convective cycling and pressure-driven flow can sometimes cause the planet's most fluid layer of mantle to move even faster than the tectonic plates that ride atop it.

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 ...

Ancient deformation of the lithosphere revealed in Eastern China

Seismic investigations from the Qinling-Dabie-Sulu orogenic belt in eastern China suggest that this region was affected by extreme mantle perturbation and crust-mantle interaction during the Mesozoic era. The Qinling-Dabie-Sulu ...

Subducting oceanic plates are thinning adjacent continents

The continental margins of plates on either side of the Atlantic Ocean are thinner than expected, and an international team led by a Rice University scientist is using an array of advanced tools to understand why.

Looking for a new gold mine? We've got the map

As published this month in Nature Geoscience, researchers and industry partners have produced the first major 'cat scan of the earth'. Their work reveals a new chart of the sub-continental lithosphere mantle and its potential ...

Lithosphere

The lithosphere ( /ˈlɪθəsfɪər/; Greek: λίθος [lithos] for "rocky" + σφαῖρα [sphaira] for "sphere") is the rigid outermost shell of a rocky planet. On Earth, it comprises the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater.
