Web17 Sep 2024 · Elucidating the oxidation state of the supra-subduction mantle wedge is important, not least because of the multiple valence states that volatile elements (e.g. S, Cl) in slab-derived fluids may be present in, prior to and during the onset of melting of the mantle wedge (e.g. Canil et al., 1994; Parkinson & Arculus, 1999; Lee et al., 2005; Bénard … WebSubduction zones are plate tectonic boundaries where two plates converge, and one plate is thrust beneath the other. This process results in geohazards, such as earthquakes and volcanoes. These hazards affect millions of people around the world, particularly around the edges of the Pacific Ocean, which mainly consist of subduction zones.

WebIn geology, subduction is the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates converge. Regions where this process occurs are known as subduction zones. WebIntroduction. Subduction zones form where a plate with thinner (less-buoyant) oceanic crust descends beneath a plate with thicker (more-buoyant) continental crust.
