The Cascadia subduction zone, where the oceanic Juan de Fuca plate descends beneath the overlying North American plate, extends 1100 km from northern California to northern Vancouver Island.

Emerging evidence suggests that plate tectonics, or the recycling of Earth's crust, may have begun much earlier than ...

Many spectacular volcanoes are found along subduction zones, such as the "Ring of Fire" that surrounds the Pacific Ocean. When two oceanic plates converge, a deep trench forms, such as the Mariana ...

The Pontus oceanic plate that was reconstructed by Suzanna ... An earlier study showed that a large subduction zone must have run through the western paleo-Pacific Ocean, which separated the ...

Initially, subduction of the shallowly-dipping oceanic Izanagi plate (flat-slab subduction) from the east led to thickening of the overriding NCC crust of the Eurasian plate as it was shortened ...

A subduction zone, composed of the deep Aleutian ... This zone marks the interface where the denser Pacific oceanic plate subducts beneath the less dense continental North American plate.

Continental plates are usually quite thick (between 35 to 70 km) compared to the much thinner oceanic plates (between 5 and 10 km). The oceanic rocks are usually made from basalt, while ...

suggests that convergent plate margins were over-thickened through either warm subduction or hard collision of the thick ...

That's when the geological record reveals plentiful ophiolites — bits of oceanic crust shoved ... rocks that form in subduction zones, or areas where the plates collide and dive into the ...
