AB: The mid Norwegian continental margin lies along the path of the North Atlantic Drift, an extension of the Gulf Stream, and therefore experiences changes in the ocean circulation that are reflected in the sedimentary record. Coupled with this is the climatic deterioration that triggered the growth and oscillations of the Quaternary ice sheets in the northern hemisphere. We will here present the depositional evolution of the mid Norwegian margin as witnessed by the mineralogy of Neogene sediments recovered as part of the site investigations performed for the Ormen Lange gas field. The results will be put into the context of the seismic and sedimentary stratigraphy that has been established for the area that shows a Neogene development from pelagic through contouritic sedimentation to the deposits left by Quaternary glacial/interglacial fluctuations and which has provided the backdrop for the Storegga submarine slide.
