Back-arc basin evolution is driven by processes active at the main subduction zone typically assuming the transition from an extensional back-arc, during the roll-back of a mature slab, to a. ocean convergence producing island arcs (e.g. Aleutian islands, Japan, New Zealand), sometimes with a double arc one further back from the subduction zone, and ocean-continent convergence producing cordillera (e.g. Andes) – continental arcs. Oceanic island arcs should not be confused with ocean island chains such as the Hawaiian islands. There are ab km (31, mi) of convergent plate margins, mostly around the Pacific Ocean—the reason for the reference “Pacific-type” margin—but they are also in the eastern Indian Ocean, with relatively short convergent margin segments in the Atlantic Ocean and in the Mediterranean ly, there are over 50 major ocean trenches covering an area of million km2 or.

Island arcs, deep sea trenches, and back-arc basins. [Manik Talwani; Walter C Pitman; W Maurice Ewing;] -- Some basic problems related to thermo - mechanical aspects of trench -arc systems are discussed.

The origin of high heat flow, volcanism and back arc basins, in particular, is considered from two. Large regions of the ocean basins are rimmed with arcuate chains of volcanic islands and adjacent parallel deep-sea trenches.

This parallelism is even more striking if the submarine ridges and basins associated with these island chains are considered. Back-arc basins are geologic basins, submarine features associated with island arcs and subduction are found at some convergent plate boundaries, presently concentrated in the western Pacific of them result from tensional forces caused by oceanic trench rollback (the oceanic trench is wandering in the seafloor direction) and the collapse of the edge of the continent.

Island arcs can either be active or inactive based on their seismicity and presence of arcs are ridges of recent volcanoes with an associated deep seismic zone. They also possess a distinct curved form, a chain of active or recently extinct volcanoes, a deep-sea trench, and a large negative Bouguer anomaly on the convex side of the volcanic arc.

Island arcs are linear mountains that divide the basins of the marginal seas from the deep-sea trenches. The foundations of island arcs are underwater mountain ranges from 40–50 to – km wide and up to 1, or more km long, composed primarily of volcanic strata of basalt, a mixture of andesite and basalt, or andesite.

American Geophysical Union, Maurice Ewing Series 1, Some active back-arc basins and back-arc rifts such as the Lau Basin, Manus Basin and Okinawa Trough are also non-isostatically held by the underlying slab.

In contrast the actively spreading Mariana Trough has water depths greater than 3, m with nearly zero free-air : Kazuo Kobayashi.

Oceanic trenches are topographic depressions of the sea floor, relatively narrow in width, but very long. These oceanographic features are the deepest parts of the ocean floor. Oceanic trenches are a distinctive morphological feature of convergent plate boundaries, along which lithospheric plates move towards each other at rates that vary from a few millimeters to over ten centimeters per year.

The East Sea is a semienclosed backarc basin surrounded by the Asian continent and the Japanese islands. It consists of three deep basins separated by submarine topographic highs such as the Korea Plateau, Oki Bank, and the Yamato Ridge (Figure ).The topographic highs are made of relatively shallow-seated acoustic basements of rifted continental crust and the overlying thin sedimentary.

To the east of the island arc, the m-deep Andaman Sea (Figs. and B) is a back-arc basin. The floor of the Andaman Sea is split along the ENE–WSW-trending rift valley cut by a series of N–S- to NNW–SSE-oriented right-lateral strike-slip faults (Kamesh Raju, Murty, Amarnath, &.

A back-arc basin occurs on the side of the overriding plate and a fore-arc basin forms toward the subducted plate side. Typically, a deep oceanic trench, such as the MarianasTrench, bounds an island.

Back-arc basins are geologic basins, submarine features associated with island arcs and subduction zones. They are found at some convergent plate boundaries, presently concentrated in the western Pacific Ocean.

Most of them result from tensional forces caused by oceanic trench rollback and the collapse of the edge of the continent. [11] Leng W, Gurnis M () Subduction initiation at relic arcs. Geophys Res Lett CrossRef Google Scholar [12] Niu YL, Tang J () Origin of.
