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

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

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.

The chemical signature of rocks formed in subduction zones (where one plate has slipped beneath another) is distinctive in its low quantity of the element Niobium. Scientists thought finding the age ...
