Back-arc basin - Wikipedia
A back-arc basin is a type of geologic basin, found at some convergent plate boundaries. Presently all back-arc basins are submarine features associated with island arcs and subduction zones, with many found in the western Pacific Ocean .
Back-arc basin | Subduction Zone, Tectonic Plate & Oceanic Crust ...
Back-arc basins are sites of significant hydrothermal activity, and the deep-sea vents that occur in these regions often harbour diverse biological communities. Examples of back-arc basins include the Sea of Japan, the Kuril Basin in the Sea of Okhotsk, the Mariana Trough in the Philippine Sea, and the South Fiji Basin.
弧後盆地 - 维基百科，自由的百科全书
弧後盆地 （Back-arc basins）是屬於隱沒系統中的地質構造單元。 弧後盆地即在隱沒帶，坐落於火山弧後面的盆地，即稱之 [1]。 弧後盆地最廣為討論的應屬分布在西太平洋一系列的弧後盆地，如： 日本海 、 馬里亞納海槽 、 勞盆地 等。 此外，因其分部特徵大多位在大陸與海洋的邊緣，亦可稱之為邊緣海盆（marginal basin），有些弧後盆地會介於兩個火山弧之間，是以也有些被稱為弧間盆地（interarc basin）。 剖面顯示了弧後盆地的發育過程。 擴張中產生了新的海洋 …
Back-arc basins: A global view from geophysical ... - ScienceDirect
2023年1月1日 · By the tectonic nature of the overriding plate (the downgoing plate is always oceanic) the back-arc basins are split into active BABs formed by ocean-ocean, arc-ocean, and continent-ocean convergence, and extinct back-arc basins.
What Is The Back-arc Basin? - WorldAtlas
2018年1月9日 · Back-arc basins emit basalt rocks that are unique to other mid-ocean ridge basalts in that they contain high levels of magmatic water. In fact, these formations are well known for their hydrothermal activity. Where deep-sea vents emerge through these basins, a large number of biodiverse species and marine communities can often be found.

Back-arc region - Wikipedia
The back-arc region is the area behind a volcanic arc. [1] In island volcanic arcs, it consists of back-arc basins of oceanic crust with abyssal depths, which may be separated by remnant arcs, similar to island arcs. [1] In continental arcs, the back-arc region is part of the continental platform, either dry land or forming shallow marine ...
Backarc Basin - an overview | ScienceDirect Topics
An oceanic arc is a line of volcanoes created by partial melting of the mantle wedge overlying the subducting slab (Wyllie, 1973; Ringwood, 1974). The forearc basin is located between the trench and the arc while the backarc basin is on the opposite side of the arc.
