The answer to the question above is the forearc basin.
Forearc basins are characterized by thick sequences of relatively underformed sedimentary rocks. Examples of the forearc basins are Banda Forearc, Luzon arc-forearc, Tohoku forearc, Central Andean forearc, Savu-Wetar forearc, and between the Western Cordillera and Peru-Chile Trench.
