As it migrated off shore, it produced the New England Seamount Chain in the NW Atlantic.
As a consequence of the strong magmatic activity within the plates, as well as at the mid-ocean ridges, new oceanic crust, highly elevated oceanic plateaus, oceanic islands, and seamounts were rapidly formed.
Globally, almost all subma- rine high plateaus and a large number of seamounts were formed in the Cretaceous superplume period.
Seamounts on the subducting plate create a somewhat different kind of subduc- tion erosion.
Single seamounts scrape material from the frontal tip of the accretionary wedge along the upper plate and carry it into the subduction zone (frontal erosion).
