Abstract:

The misfit of two triangulation nets in East Greenland established in 1870 and 1907 was a stimulus to Wegener's west-drift concept. An analysis of the regional structure of East Greenland shows intermittent tensional tectonics in the late development of the Caledonian architecture and two distinct periods of crustal widening along linear belts in the Late Jurassic and the Paleogene. Neogene and postglacial tensional structures are recorded in Iceland. The amount of crustal widening, however, is inconsiderable in comparison to postulates by advocates of the drift concept.
