Lower Cretaceous stratigraphy and tectonics of the south-southeastern Norwegian offshore

Abstract

The Early Cretaceous sedimentary sequence is subdivided into seven formations in the southern Norwegian Offshore. It is dominated by marine fine-grained argillaceous sediments with varying calcareous content. The Sola Formation is found to be relatively rich in organic carbon and is, therefore, expected to have a good source rock potential. A small number of sandstone accumulations is located in the vicinity of penecontemporaneously reactivated highs. The northern part of Fiskebank Sub-Basin was inverted during the Cenomanian. This correlates with renewed strike-slip movements along the Fjerritslev Fault and at other places at the edge of the Fennoscandian Shield. The 'Late Kimmerian Unconformity' is discussed.
