Newly published research has revealed that compositional rock anomalies within oceanic plates caused by ancient tectonics influence the trajectory and speed of the plates as they plunge deep into ...

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.

Scientists have discovered an unusually thick mantle transition zone beneath the Lesser Antilles. This discovery sheds new light on how oceanic plates sink into the Earth's mantle. Variations ...

Recent discoveries offer deeper insight into the movement of tectonic plates. New research has found that variations in rock ...

Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed ...

In regions of convergence, one plate can sink under another in a subduction zone, or two colliding plates can form a mountain belt. At divergent boundaries, plates move away from each other and ...

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 ...

New findings provide a greater understanding of plate subduction, or how tectonic plates ... that compositional rock anomalies within oceanic plates caused by ancient tectonics influence the ...

At a destructive boundary the plates are moving towards each other. This usually involves a continental plate and an oceanic plate. The oceanic plate is denser than the continental plate.

Oceanic transform faults have historically been thought of as simple, predictable features. They represent the least well-studied of the three major plate boundaries, which include divergent ...
