Massive igneous activity across a 2000-km- diameter region accompanied the continental breakup that generated the North Atlantic Ocean. I outline the evidence which suggests that the mag-matism was caused by passive upwelling and decompression melting of asthenospheric mantle which was 150-200 °C hotter than normal. The anomalously hot mantle was introduced by the ini-tiation of the Iceland plume shortly before continen-tal breakup. Although the melt was caused by passive upwelling beneath the rifts, initiation of the mantle plume probably triggered the breakup by introducing regional uplift.

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.
