Abstract

Abstract

The Magellan seamount trail includes tens of isolated guyots trending EW.A backtracking method and a hot-spotting method were used to trace the Magellan seamount trail from the movement of a plate and its geometry based on previous studies in this region. The result shows that the Magellan seamount trail is the collective products of intraplate volcanism originating from multiple hot spots and plate tectogenesis. The Magellan seamount trail is derived from the present French Polynesian hot spots trending NNW during the Cretaceous. They are also affected by the activity of two fracture zones, which trend SN and NNW, and thermal activity with the movement of the plate. Finally the present Magellan seamount trail is formed.
