Earth's crust today has a surprisingly similar composition to the planet's first outer shell, or "protocrust," new research ...

"They are evolving by themselves, simply through the process of subduction of oceanic crust." That doesn't mean there isn't dense material from Earth's youth at the bottom of the mantle ...

New research reveals a surprising link between the ancient tectonic history of oceanic plates and their fate as they subduct ...

Crustal earthquakes, whose magnitude may exceed 7 in some cases, occur within the overriding North America plate as it deforms in response to the subduction process. The 1946 magnitude 7.3 event that ...

Researchers found that an inactive subduction zone under the Strait of Gibraltar may begin migrating into the Atlantic Ocean, commencing the shrinking process. The zone also brings a higher risk ...

Mid-ocean ridge basalts (MORBs), located far from subduction zones, are typically thought to be unaffected by subduction ...

Newly published research has revealed that compositional rock anomalies within oceanic plates caused by ancient tectonics ...
