Scientific paper

We present here an interpretation of geological and geophysical data collected in the Newfoundland Basin. Geophysical measurements indicate that the area was formed by sea-floor spreading during the Cretaceous. Rocks collected from the Newfoundland Seamount chain support this interpretation and their chemistry suggests affinities with volcanic rocks found on oceanic islands but not with those sampled on mid-ocean ridges. A schematic model for early plate motions between Iberia and North America beginning about 115 m.y. B.P., consistent with the data, is discussed.
