Plate Tectonics of the Western Atlantic
From NSwiki, the NationStates encyclopedia.
There are three tectonic plates in the Western Atlantic. They include the Vasconian, Ambaran and Gulf Plates. The Vasconian Plate has a boundary with the Ambaran Plate to the south and west and the Gulf Plate to the south and east.
The Ambaran Plate is a continental tectonic plate covering the continent of Ambara, extending westward several hundred miles into the Pacific Ocean and westward only a few miles before meeting the Gulf Plate.
