Late Jurassic sedimentary bedrock north of Utsira, offshore western norway

Recent shallow marine investigations have revealed ca. 150 km2 of Late Jurassic sedimentary bedrock north of Utsira in an area previously mapped as crystalline basement. The rocks, which are charac­ teristically truncated by a marked regional planar angular unconformity further offshore, continue to rise well above this leve! into shallower waters. This shallower remnant is very unusual in Norwegian coastal waters not just because it survived the full force of the erosional event, but also because it is in lateral continuity with Jurassic rocks on the Continental Shelf.
