This study, published in Earth and Planetary Physics, explores the subduction thermal state, slab metamorphism, and seismic ...

Unlike standard subduction, in which a tectonic plate descends beneath another plate into Earth, flat slab subduction is a process in which a tectonic plate descends to depths of about 30 to 60 ...

Subduction is a process where one tectonic plate slides beneath another, which typically consumes slabs of oceanic crust entirely. Yet, in this case, the ancient slab remains trapped deep within ...

Scientists observed subduction as well as a process known as flat-slab rollback, which is "when the subducting plate retreats back to the surface." The processes led to the lithosphere ...

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.

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 ...

Microphotograph of amphibole (brown) and plagioclase (grey-white) minerals present in an adakitic rock from the western Trans-Mexican Volcanic Belt (TMVB) Focus: occurence of adakite rocks and their ...

Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones. As these older sections of plates sink, newer and less dense sections of plate are pulled along behind.

All of these regions may have undergone early flat-slab subduction, with varying subsequent tectonic activities, according to Professor Liu. The study highlights that ancient lithosphere can break ...
