Eiken & Austegard (1987) have presented a number of seismic sections offshore, west of Spitsbergen, which highlight a series of graben structures infilled with sediments interpreted to be of Tertiary age. This age is contested, based on grab-sample data and correlation with adjacent basins onshore, along the west coast of Spitsbergen. It is suggested that these offshore basins may be infilled with sediments of late Paleozoic and Mesozoic age.
