Forearc basin is one of the major elements of plate convergent margins (e.g., [1, 2]).The formation is considered to be closely associated with accretion or erosion at frontal and basal parts of accretionary wedge (e.g., [3–5]).Especially, the seaward margin of the basin is directly affected by uplift and subsidence of the outer …

Forearc is a plate tectonic term referring to a region between an oceanic trench, also known as a subduction zone, and the associated volcanic arc. Forearc regions are present along a convergent margins and eponymously form 'in front of' the volcanic arcs that are characteristic of convergent plate margins. A … See more During subduction, an oceanic plate is thrust below another tectonic plate, which may be oceanic or continental. Water and other volatiles in the down-going plate cause flux melting in the upper mantle, creating magma … See more The forearc region includes any forearc basin, outer-arc high, accretionary prism and the trench itself. The accretionary prism is located at the slope of the trench break where there is significantly decreased slope angle. Between the break and the magmatic … See more One good example is the Mariana forearc, where scientists have done extensive research. In this setting there is an erosive margin and forearc slope which consists of 2 km high and 30 km diameter serpentine- mud volcanoes.

Combining structural geology and a source-to-sink thermochronological study, we show that the flat slab period is contemporaneous with uplift accommodated by large-scale crustal extension in the forearc.
