Divergent double subduction (abbreviated as DDS), also called outward dipping double-sided subduction, is a special type of subduction process in which two parallel subduction zones with different directions are developed on the same oceanic plate.
20 de abr. de 2017 · Divergent double subduction (DDS) is a potential way for closure of oceanic basins in plate tectonics, but its mechanism remains unsolved. The Molucca Sea subduction zone in SE Asia is a unique Cenozoic example of DDS. In this study, we present 3-D numerical modeling of how DDS occurs.
Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
19 de feb. de 2024 · Subjects. Geodynamics. Tectonics. Abstract. Face-to-face double subduction systems, in which two oceanic plates subduct toward each other, are essential elements of plate tectonics. Two...
13 de abr. de 2021 · Subduction of the oceanic lithosphere, as the engine that drives plate tectonics, has played a key role in the theory. However, one of the biggest unanswered questions in Earth science is how the first subduction was initiated, and hence how plate tectonics began.
17 de mar. de 2020 · Recent studies show that subduction reversal can in particular occur in a divergent double subduction zone when the slab pull of one slab exceeds that of the other, shorter one, which then experiences a net upward pull.
28 de oct. de 2022 · The coexistence of divergent (spreading ridge) and convergent (subduction zone) plate boundaries at which lithosphere is respectively generated and destroyed is the hallmark of plate...
