  Heimdal Formation
  
  Name

  Named by Deegan & Scull (1977) after the Heimdal Field on the Norwegian continental shelf. Heimdal was a son of the Norse god Odin, and one of the principal gods in Norse mythology.

  Well type section

  Norwegian well 25/4-1 from 2423 m to 2067 m, coordinates N 59°34'27.30", E 02°13'22.60" (Fig 5.52) . 36 m of cores from the upper part of the formation, and 6.5 m from the lower part.

  Well reference section

  Norwegian well 15/9-5 from 2684 m to 2448 m, coordinates N 58°24'12.47", E 01°42'29.20" (Fig 5.42) . No cores.

  Thickness

  The Heimdal Formation is 356 m thick in the type well and 236 m thick in the reference well. It thins rapidly east of these wells and south of well 15/9-5 .

  Lithology

  The formation is dominated by thick units of poorly sorted, fine to coarse grained, poorly cemented sandstones with variable amounts of mica, glauconite and detrital lignite. The sandstone units are interbedded with grey and black shales, limestones and sandy limestones. There is a wide range in number and thickness of interbedded lithologies. In general, the amount of carbonate increases towards the base of the formation.

  Basal stratotype

  The lower boundary of the Heimdal Formation is usually marked by a transition from the Lista Formation into the interbedded sandstones of the Heimdal Formation. The log response is characterised by lower gamma-ray readings and higher velocities when entering the overlying Heimdal Formation (Fig 5.52) . The Heimdal Formation locally overlies the cleaner sandstones of the Ty Formation . In that case, the lower boundary is placed where clean sandstones give way to the interbedded sandstones of the Heimdal Formation. These formations are normally separated by the Lista Formation .

  Characteristics of the upper boundary

  The upper boundary is usually defined by a transition into the Lista Formation shales and is then characterized by higher radioactivity and lower velocity (Fig 5.52) . Locally, the Heimdal Formation is overlain by the Hermod Formation , the upper boundary therefore being defined by a change into clean, "blocky" sand.

  Distribution

  The sandstones of the Heimdal Formation are distributed in a broadly lobate pattern eastwards from the western margin of the Viking Graben. Their approximate distribution on the Norwegian continental shelf is shown in (Fig 5.47) .

  Age

  Paleocene.

  Depositional environment

  In the westernmost areas (East Shetland Platform/Fladen Ground Spur), the Heimdal Formation was deposited on a shallow-marine shelf under high-energy conditions. In the Viking Graben, the formation was deposited as submarine fans derived from sand accumulations on the shallow shelf to the west. The shale layers consist partly of the fine fraction of the turbidity currents and of hemipelagic mud.

  Remarks

  In a narrow belt extending from the eastern part of quadrant 15 (Fig 5.47) , the Heimdal Formation is developed as a clean sandstone without interbedded shales. This is described as the Meile member .
