Abstract

Controversy exists concerning the timing and tectonic setting for the development of the Palaeogene Forlandsundet Basin relative to deformation of western Spitsbergen and the opening of the Nowergian-Greenland Sea. New data and observations from this basin lead us to advocate abandonment of the concept of the basin as a fault-bounded graben with a simple extensional history. The basin's modern structural geometry, that of a graben, is a response to late tectonism and should not be used to infer the origin and early development of the basin, an origin that was coeval with Palaeogene shortening and strike-slip deformation along Svalbard's western margin. -from Authors
