subduct การใช้

• That is the reason why oceanic plates always subduct under another plate.
• The Kula Plate is an ancient subduct under Alaska.
• Hence it is difficult in this case to subduct water through the thermohaline circulation.
• When two plates containing continental crust collide, both are too light to subduct.
• At Taitao, the Chile Triple Junction and the Nazca Plate subduct the South American Plate.
• Plate tectonics also provided the mechanism by which the former ocean disappeared : oceanic crust can subduct under continental crust.
• Around 200 million years ago an ancient oceanic plate named the Farallon Plate began to subduct beneath the North American Plate.
• On Earth, colliding plates either subduct _ one plate slipping below the other _ or wrinkle up to form mountain ranges.
• In between these two ridge trench encounter points, a small triangular shaped plate continued to subduct between Brisbane and Coffs Harbour.
• About 15 million years ago in the Miocene the Chile Ridge begun to subduct beneath southern tip Patagonia ( 55?S ).
• As oceanic crust and underlying lithosphere subduct, water is released by dehydration reactions, along with water-soluble elements and trace elements.
• Somewhere near the end of the Devonian, a subduction zone developed under the Mid-German / Normannian highs and Rhenohercynian crust began to subduct.
• Such a lithosphere would not sink deeply or subduct, because of its buoyancy and the removal of denser melt that in turn increased the density of the residual mantle.
• The indenter block is too buoyant to subduct, so crustal accommodation is achieved by either shallow underthrusting and crustal thickening, or formation and later lateral displacement of several microplates.
• Due to the relatively young age of the basin, many researchers are interested in learning how the basin will continue to develop over time and how the plates will subduct.
• South of New Zealand the boundary becomes a transitional transform-convergent boundary, the Macquarie Fault Zone, where the Australian Plate is beginning to subduct under the Pacific Plate along the Puysegur Trench.
• This shallow subduction appears to be triggered by the Nazca Ridge and the Juan Fernandez Ridge; the areas where they subduct beneath the Peru-Chile Trench coincide with the limits of the Central Volcanic Zone.
• The CLIP drifted into the same area, but as it was less dense and thicker than the surrounding oceanic crust, it did not subduct, but rather overrode the ocean floor, continuing to move eastward relative to North America and South America.
• There is water in the rocks of the oceanic plate ( because they are underwater ), and as this plate moves further down into the subduction zone, much of the water contained in the plate is squeezed out when the plate begins to subduct.
• This could be associated by the spreading of the Mid-Indian Oceanic ridge and the East African rift . To accommodate the compression of the Somalian plate due to two extensional edges of the plate the oceanic plate might begin to subduct below the continental plate.
