Abstract

Summary The Palaeocene of the North Sea basin between 58°N and 62°N contains a number of reservoir sands. The regional tectonic setting, which was dominated by subsidence in the Viking Graben and Witch Ground Graben areas had an important influence on the thickness and distribution of the Palaeocene sands. Following deposition of the Danian, middle Palaeocene sedimentation was controlled by uplift and faulting along the flanks of these areas with large quantities of sand being shed off the East Shetland Platform. These sands were deposited in a nearshore shallow marine environment. With a decrease in tectonism, late Palaeocene deposition was dominated by the outbuilding of a delta system in the Moray Firth area with the northward spread of sands along the edge of the East Shetland Platform. At this time, the basin became increasingly cut off from open marine circulation. The top of the Palaeocene is marked by a regional unconformity representing a late Palaeocene-early Eocene transgression which affected much of northwestern Europe.
