Ocean-continent Transition to Suprasubduction Zone Origin of the Western Yarlung Zangbo Ophiolites in SW TibetTransient Evolution of the Neotethyan Oceanic LithosphereOIBThe ophiolites that crop out discontinuously along the~2000 km Yarlung Zangbo Suture zone(YZSZ)between the Nanga Parbat and Namche ...
(i.e. not deformed by Alpine tectonism) betweenserpentinitesandpelagic sedimentsis interpreted as sub-continental mantle tectonic denudation. In effect, the characteristics of a part of Alpineophiolitesare those of the continent–ocean transition zone comparable to the ‘oceanic’ basement of the...
There are places deep beneath the waves of our planet's oceans that remain mysterious and almost unexplored. Some are so deep that their bottoms are as far away from us as the upper reaches of our atmosphere. These regions are called the deep ocean trenches and if they were on a continen...
The BABB-like MORB, on the other hand, mostly occur behind ocean-continent subduction zones. Such a variation in subduction modes may lead to varied slab flux compositions, as multiple mechanisms may generate the slab flux released beneath arcs36,37. That said, all forms of slab flux should ...
2, ocean-continent connection zones between the two oceans, including: (1) properties of continental margin basement, for example, if the crusts of the Okinawa Trough, the Okhotsk Sea, and east of New Zealand are continental crust or oceanic crust, and the origin of micro-continent in oceans...
Slab pull happens at the subduction zone. So to continue our example… As the ocean floor plate begins to sink down into the mantle, it would drag or pull the entire plate along with it. So more and more of this plate, the ocean floor, would go down under the continent into the ...
That ridge then divides near the center of the Indian Ocean basin into the Central Indian Ridge that runs north into the African continent and the Southeast Indian Ridge that runs east below the Australian continent. The ridge continues eastward along the southern portion of the Pacific Ocean ...

A continental shelf extends out from a continent and is a relatively shallow area of the ocean. As shown in the image on the right-hand side, the extent of continental shelves vary — some continental shelves are narrow strips of underwater seabed, while others may extend several hundred kilo...
