Stratigraphic correlation of late Palaeocene sand deposits in the Søgne Basin area of the Danish and Norwegian central North Sea

Abstract

A stratigraphic analysis of late Palaeocene sands of the Søgne Basin and the western part of the Norwegian–Danish Basin shows that the sand bodies are of differenct ages. The geographic distribution of the sand deposits shows that they are related to underlying Mesozoic structures suggesting a controlling effect of Tertiary tectonics on the deposition of sand during the late Palaeocene. However, the structural setting of various sand bodies varies from reactivation of older faults and reactivation of salt structures. The local character of the structures active during the late Palaeocene introduces minor depressions with no lateral connection. The sand bodies, which are interpreted as having been deposited in these depressions, are thus in general separate bodies with no lateral connection. The Fennoscandian shield and eroded Mesozoic sediments along the Fennoscandian Border Zone are suggested as source area for the late Palaeocene sand deposits.

Morphology and origin of major Cenozoic sequence boundaries in the eastern North Sea Basin: top Eocene, near‐top Oligocene and the mid‐Miocene unconformity

“…In contrast, the up to 250‐m‐thick southward‐prograding wedges south‐west of Norway contain thick sand‐rich intervals ( Michelsen et al ., 1995 , 1998), indicating that Norway acted as a source area throughout the early–middle Paleogene. A significant supply of coarse‐grained clastic sediments from southern Norway during the early Paleogene is also indicated by the occurrence of sand‐rich intervals in the otherwise fine‐grained succession of the Central Trough ( Danielsen et al ., 1995 ).…”

Discrimination of density flow deposits using elemental geochemistry—Implications for subtle provenance differentiation in a narrow submarine canyon, Palaeogene, Danish North Sea

“…2). Gravity flows, initiated by slumping events in the glauconite-producing shelf areas of the Stavanger Platform, transported the sands up to 120 km through the submarine canyon before deposition at their present day location (Danielsen et al, 1995;Hamberg et al, 2005). The sandstones are referred to five different members depending on their position in the shale succession of the canyon fill (Fig.…”
