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.

Melting by conduction when magma transfers heat to rocks having a lower melting temperature. the mecca seattle waWebBack-arc basins are formed when a subducting slab increases its angle of descent, which causes its deep-sea trench to migrate away from the overriding plate. This allows the overriding plate to stretch out, which creates a region of thin lithosphere called the back-arc basin. (Group 2) Bottom Picture-. the mecca shoes

"WebIt should be noted, however, that uncertainty in gabbro K 2 O has a huge impact on subsequent calculations of total K 2 O flux into subduction zones: using the log-based value, instead, would increase computed total K 2 O flux by 71%. 4.

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. WebJan 23, 2024 · Flux Lattice in Superconductors and Melting.
