Flux melting subduction zone
WebTerms in this set (135) Flux melting most likely occurs at: (A) Mid-ocean ridges. (B) Transform faults. (C) Subduction zones. (D) None of the above. (C) Subduction … WebFlux melting occurs as a result of the addition of volatiles. These volatiles lower the melting temperature of a hot rock. Common volatiles would include H20 and C02. An example of an environment where this would occur would be at subduction zones because the subduction carries water into the mantle causing flux melting.

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 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.
WebFlux melting or fluid-induced melting occurs in island arcs and subduction zones when volatile gases are added to mantle material (see figure: graph D, label Z). Flux-melted … WebJan 25, 2024 · The compaction-derived water discharge rates estimated for the 5-cm-diameter orifice at Pythia’s Oasis (4 × 10 3 to 11 × 10 3 m 3 year −1), therefore, account for 29 to 79% of the accreted pore water flux, 50 to 100% of the underthrust flux, and 18 to 50% of the total annual pore water flux into the subduction zone per kilometer of trench ...

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.
