Subduction Earthdata

Subduction is a geological process in which the oceanic lithosphere and some continental lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the … See more According to the theory of plate tectonics, the Earth's lithosphere, its rigid outer shell, is broken into sixteen larger tectonic plates and several smaller plates. These plates are in slow motion, due mostly to the pull force of subducting … See more Initiation of subduction Although stable subduction is fairly well understood, the process by which subduction is initiated remains a matter of discussion and … See more Modern-style subduction is characterized by low geothermal gradients and the associated formation of high-pressure low-temperature rocks such as eclogite and blueschist. Likewise, rock assemblages called ophiolites, associated with modern-style subduction, … See more Subduction zones are important for several reasons: • Subduction zone physics: Sinking of the oceanic lithosphere (sediments, crust, mantle), by the contrast of density between the cold and old lithosphere and the hot asthenospheric … See more Arc-trench complex The surface expression of subduction zones are arc-trench complexes. On the ocean side of the complex, where the subducting plate first approaches the subduction zone, there is often an outer trench high or … See more Metamorphism Subduction zones host a unique variety of rock types created by the high-pressure, low-temperature … See more Harry Hammond Hess, who during World War II served in the United States Navy Reserve and became fascinated in the ocean floor, studied the Mid-Atlantic Ridge and proposed that hot molten rock was added to the crust at the ridge and expanded the … See more WebDec 16, 2024 · In subduction, the plates are forced to sink due to high energy into the mantle.
