The North Atlantic basin evolved over a hundred million years, starting with an episode of Triassic rifting, followed by separation of Africa and North America in the Middle Jurassic. The tear spread northward between Iberia and the Grand Banks in the Early Cretaceous, and finally parted the European-Greenland and North American plates in the latest Cretaceous. Several episodes of extension are recognizable. In the south, rifting was followed by ocean opening and passive margin subsidence, whereas extensional tectonics prevailed farther north.

Extensional Tectonics and Stratigraphy of the North Atlantic Margins
Stimulated by the wealth of frontier exploration data and deep seismic surveys about the North Atlantic margins, this publication was crafted to provide a comprehensive analysis of North Atlantic extension. The 40 papers in this volume are divided into 6 sections: concepts, North Atlantic perspectives, North American margins, European-African margins, North Sea and Barents Shelf, and analogs. This book is concerned primarily with the circum-North Atlantic data base. It is largely biased toward presentation and interpretation of data rather than being model driven. The book includes comparative stratigraphic columns for basins of the North Atlantic margins.
