“We discovered how subduction works during the plate tectonic revolution in the 60s,” he said. “First, we had discovered the oceanic crust actually moves. People thought it used to just sit there, but ...

Thin oceanic crust is formed by decompression melting of the upper mantle at mid-ocean ridges, but the origin of the thick and buoyant continental crust is enigmatic. Juvenile continental crust ...

The Earth's oceanic crust covers an enormous expanse, and is mostly buried beneath a thick layer of mud that cuts it off from the surface world. Scientists now document life deep within the ...

The oldest patch of undisturbed oceanic crust on Earth may lie deep beneath the eastern Mediterranean Sea – and at about 340 million years old, it beats the previous record by more than 100 ...

The segregated oceanic crust may stay at the bottom of the mantle transition zone for the negative buoyancy and this can well explain the observed seismic scattering and week P660P phase.

The crust Earth's oceanic crust is mostly made up of basalt rock. (Image credit: guenterguni/Getty Images) The crust is split into oceanic crust and continental crust.

On land, continental crust, once created, can remain more or less unaltered for billions of years. But the oldest oceanic crust is only about 200 million years old, as new crust is continually ...

Persisting in microscopic cracks in the basalt rocks of Earth's oceanic crust is a complex microbial ecosystem fueled entirely by chemical reactions with rocks and seawater, rather than sunlight ...

Scientists have recently documented that oxygen is disappearing from seawater circulating through deep oceanic crust, a significant first step in understanding the way life in the "deep biosphere ...

(Phys.org)—Debate over how and where oceanic island chains, like Hawaii, form, is at an end according to an academic from The Australian National University.
