Dickinson (1973) applied the term "arc-trench gap" to the zone between the trench slope break and the volcanic axis, a region that includes the frontal arc and part of the forearc. The width of the arc-trench gap varies from 50 km to 250 km and increases in proportion to the duration of magmatic activity in the arc. 3, record 3, English, - arc%2Dtrench%20gap

Côté continent, la fosse est constituée : soit d’écailles de sédiments comprimés, d’origine océanique, qui forment le prisme d’accrétion [...]; soit par la bordure d’un arc insulaire, sédimentaire ou volcanique. [...] Cet arc correspond à un relief émergé s’intercalant entre le talus continental et la fosse océanique. Il est formé soit par l'empilement des sédiments océaniques et correspond donc aussi à un prisme d’accrétion, soit par le volcanisme. Le relief, quelle que soit sa nature, délimite un bassin d’avant-arc, de faible profondeur où s’accumule une sédimentation essentiellement détritique. L'arc sédimentaire n’ est pas toujours présent, mais il y a toujours un arc volcanique(qui peut être situé sur le continent). 2, record 4, French, - arc%20insulaire%20s%C3%A9dimentaire
