North Sea and Barents Shelf
Published:January 01, 1989
The Mesozoic North Sea rift forms an integral part of the Arctic-North Atlantic rift system. Rifting activity in the North Sea commenced during the earliest Triassic, peaked during the Late Jurassic-earliest Cretaceous, and terminated during the Paleocene. During the early Middle Jurassic a major rift dome developed in the central North Sea. Geophysical data indicate an important discrepancy between upper and lower crustal thinning across the North Sea rift system. This raises doubts about the concept that during rifting the crust is thinned by mechanical stretching only. It is argued that during the rifting process the Mohodiscontinuity can be seriously destabilized.

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.
