There are three stages in the history of a basin: mature (where a broad ocean basin widens, trenches eventually form, and subduction starts); declining (where the sea floor is eliminated by subduction and an oceanic ridge forms); and terminal (where the sea floor is finally eliminated and continents collide to form a continental mountain chain).
