The Comubian terrane, a microplate that came into existence during the Variscan orogeny, comprises metamorphosed Devonian and Carboniferous sediments thrust into a massive nappe pile and injected by granites. It extends from the southwest tip of Britain to the base of the continental slope at Goban Spur. The Comubian terrane remained a prominent massif unaffected by subsidence throughout the Mesozoic, and the development of the superposed and surrounding basins was significantly controlled by the positions of former thrusts and a series of NNW-SSE Variscan dextral strike-slip faults.

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.
