When plates collide, oceanic crust will be subducted under continental crust, recycling it back into the mantle. Therefore, oceanic crust never gets to age as much as continental crust, which almost ...

The Earth’s crust is disappearing right beneath our feet – and most people don’t even realise it. Now, if you’re a geologist, ...

This "virtual Earth" is the first computer model that "views" the crust and mantle as an interconnected, dynamic system, the researchers reported Oct. 30 in the journal Science Advances.

Oceanic crust formation is dynamic after all Date: November 29, 2009 Source: Brown University Summary: Earth scientists have found strong evidence that the geological processes that lead to the ...

These results suggest the existence of a process recycling marine carbon into Earth's mantle, which could contribute to ...

The hot mantle churns and circulates, moving the crust at the surface, causing the oceanic crust to dive into its depths — a process called subduction — and triggering the upwelling of vast ...

At mid-ocean ridges at the bottom ocean, where plates drift apart, new oceanic crust is constantly produced as basaltic rocks when hot volcanic lava emerges from the mantle and solidifies.

Eclogitic diamonds formed in Earth's mantle originate from oceanic crust, rather than marine sediments as commonly thought, according to a new study. Share: Facebook Twitter Pinterest LinkedIN Email.

The boundary between the brittle part of the upper mantle and the crust (both oceanic and continental) is known as the Mohorovičić Discontinuity (Moho) according to Geology.com.
