Large-scale development of the mid-Norwegian margin during the last 3 million years

Timing of massive ‘Fleuve Manche’ discharges over the last 350kyr: insights into the European ice-sheet oscillations and the European drainage network from MIS 10 to 2

“…350 ka (McManus et al, 1999;Hiscott et al, 2001;Helmke and Bauch, 2003) and the high abundance of IRD in core MD03-2692 reinforces the idea that a massive iceberg discharge from the Northern Hemisphere ice sheets occurred during this interval. Glacigenic marine deposits in the northern North Sea and along the Norwegian margin reveal the presence of an extensive FIS, with an offshore extension considered similar to that in MIS 2, during the glacial MIS 10 ( Sejrup et al, 2000;Dahlgren et al, 2002;Nygard et al, 2005;Rise et al, 2005;Sejrup et al, 2005). This indicates that ice over Europe contributed to the global glaciation and to the attendant significant low sea level which occurred during this interval (e.g.…”

First-Order Estimation of In-Place Gas Resources at the Nyegga Gas Hydrate Prospect, Norwegian Sea

“…The Late Eocene strike-slip compressive regime resulted in the development of north-south trending anticlinal features [41], of which the Ormen Lange dome is one. Within the last 3 million years, extensive deposition of glacially derived materials of the Naust Formation dominated the area, resulting in a sediment package well over 1000 m thick in places [42]. Its depositional regime is highly dependent on the climatic variations associated with glacial and interglacial times and the position of the ice sheet in relation to the shelf break [43].…”

Compaction of diagenetically altered mudstones – Part 1: Mechanical and chemical contributions

“…3) were made, which is coeval with the The Kvitnos Formation is overlain by around 1200 m thickness of Upper Cretaceous, Palaeogene and Neogene claystone formations, terminating at an unconformity that developed during the late Pliocene (Dalland et al, 1988;Blystad et al, 1995). Between 2.8 Ma and the present, following the late Pliocene hiatus, glaciogenic sediments of the Naust Formation have been deposited in a series of east-to-west prograding wedges (Rise et al, 2005(Rise et al, , 2006Ottesen et al, 2009;Dowdeswell et al, 2010). Their thickness ranges up to 1300 m in the study area, so the deposition rate was much more rapid after 2.8 Ma than at any earlier time during the Cenozoic era (Fig.…”
