Forearc basin example
There are two models which characterize a forearc basin formation and deformation and are dependent on sediment deposition and subsidence (see figure). The first model is associated with a forearc basin formed with little to no sediment supply. Conversely, the second model is associated with sediment supply. … See more 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 … See more The intense interaction between the overriding and underthrusting plates in the forearc regions have shown to evolve strong coupling mechanisms which result in megathrust … See more One good example is the Mariana forearc, where scientists have done extensive research.

Back-arc, arc and forearc domains undergo cycles of hundred to thousand metres scaled uplift and subsidence over temporal scales of 100 ka to 10 Ma (Lallemand and Le Pichon, 1987; Fisher et al., 1998; Sak et al., 2004; Clift and … WebJun 21, 2024 · 1. Introduction. 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 …
