Abstract
The continental margins in the Norwegian-Greenland Sea consist of rifted and sheared segments that are related to the initial opening of the ocean. Parts of the rifted margins are characterized by basement highs underlying the lower continental slope. These highs are bounded landward by a steeply dip** basement surface—escarpments—which are interpreted to define the initial line of rifting separating oceanic crust from subsided continental crust. The North Sea Basin continues northward into the Norwegian Marginal Basin and the Barents Sea and contains thick sediments of Mesozoic and possibly late Paleozoic age. This basin also contained parts that now form the Greenland margin. We believe that prior to opening, deposition and subsidence kept pace with each other in an epicontinental marine environment. However, the continental slope has subsided further with the evolution of the Norwegian-Greenland Sea.
