WebMelting aided by the addition of water or other fluid is called flux melting. It is somewhat more complicated than this, but metamorphic dewatering of suducting crust and flux melting of the mantle wedge appears to account … WebExplanation: As the subducting plate descends into the mantle, it carries water and other volatiles with it. These volatiles reduce the melting point of the mantle wedge, causing it to partially melt and form magma. This process is known as "flux melting" or "hydration melting," and it is a common way that magma is generated in subduction zones.

"WebThe mantle is made up of solid rock that is under extreme pressure and high temperature. However, if the pressure is reduced, for example, by the upward movement of tectonic plates, the rock can begin to melt. As the pressure decreases, the melting temperature of the rock decreases, allowing it to melt even though the temperature has not changed. " - Flux melting subduction zone

WebThe added water is a flux, and this type of melting is called flux-induced melting. In Figure 7.4 (right), the rock (represented by the dashed box) is not hot enough to be right of the line where dry mantle rocks melt, but it is to the right of the line where wet mantle rocks melt. Flux-induced partial melting of rock happens in subduction zones. WebJul 22, 2024 · Flux Melting. Flux melting occurs when water or carbon dioxide are added to rock. These compounds cause the rock to melt at lower temperatures. This creates magma in places where it originally maintained a solid structure. Much like heat transfer flux melting also occurs around subduction zones.

WebFlux melting. Decompression melting does not explain how volcanoes above subduction zones, since in this setting there is an increase in pressure when the oceanic plate subducts under a colder oceanic plate or a continental plate. The mechanism that explains melting in this setting is flux melting.
