Island arcs, which arise from volcanic activity along subduction zones where one tectonic plate dives beneath another, play a crucial role in the formation of the continental crust.

The subduction-zone geochemical fingerprint therefore led to the establishment of three-component mixing models to explain the composition of magmatic rocks produced at continental-arc and island ...

Island arcs form where a plate of the oceanic crust sinks beneath an adjacent plate in a process known as subduction, giving rise to a belt of volcanoes parallel to the trench where the descending ...

As a result, subduction zone arc volcanoes often produce explosive Vulcanian to Plinian events. Schematic cross section of the Mariana Islands subduction zone.

Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

Oceanography, Vol. 32, No. 1, SPECIAL ISSUE ON SCIENTIFIC OCEAN DRILLING: Looking to the Future (MARCH 2019), pp. 160-174 (15 pages) The association of deep-sea trenches—steeply angled, planar zones ...

In a recent paper published in National Science Review, a jointed team of scholars from China and UK has made significant progress in understanding the genesis of volcanic rocks in subduction ...

When a seamount enters a subduction zone, it has a major affect on forearc morphology, the uplift history of the island arc, and the structure of the downgoing slab. It is not known, however, what ...
