Because the new axis of spreading developed behind the subduction trench, the newly created oceanic crust is said to have resulted from back-arc spreading. It is noteworthy here that the newly formed oceanic crust was younger than most of the ocean-floor sediments that were being subducted nearby. 2, record 1, English, - back%2Darc%20spreading

Si l'ensemble des zones de subduction répond bien à la loi, on observe une certaine dispersion pour les arcs des Nouvelles-Hébrides, des Mariannes et du Japon.
