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.
