• Beskrivelse

  Amundsen Formation
  
  Name

  Named by Deegan & Scull (1977) who gave it "sub-unit" status.

  Well type section

  UK well 211/29-3 (Shell) from 2993m to 3051m, coord N 61°08'06", E 01°43'36.5" (Fig 3.10) .

  Well reference sections

  Norwegian wells 33/9-1 (Mobil) from 2838 m to 2923m, coord N 61°15'07.5", E 01°50'25.8" (Fig 3.11) , 31/2-1 (Shell) from 2272.5 m to 2292.5 m and from 2134 m to 2176 m, coord N 60°46'19,16", E 03°33'15.87" (Fig 3.13) . and 30/6-7 (Norsk Hydro) from 3023 m to 3151.5 m, coord N 60°38'39.49", E 02°45'21.74" (Fig 3.12) .

  Thickness

  58 m in the type well, 85 m in well 33/9-1 , 128.5 m in well 30/6-7 and 62 m in well 31/2-1 , where the formation is split by the Johansen Formation , forming an upper (42 m) and a lower (20 m) unit.

  Lithology

  In the well type section the formation consists of light to dark grey, firm, non-calcareous siltstones and shales, in part carbonaceous and pyritic. Thin, fine to coarse grained, grey calcareous and glauconitic sandstone beds are present in the marginal areas of the basin. In the Norwegian sector the formation is more calcareous, especially in the lower part.

  Boundaries

  The base of the formation is the base of the Dunlin Group (defined above). The top is marked by the change to the more regular gamma ray and sonic log response of the overlying Burton Formation . Where the Burton Formation is missing (on the Horda Platform), the upper boundary is the base of the Cook Formation .

  Distribution

  The formation is widely distributed in the East Shetland Basin and Viking Graben north of 59°N. Towards the northwest the formation appears to overstep the Statfjord Formation and rests on the Hegre Group .

  Age

  Probably Hettangian to Sinemurian or Early Pliensbachian.

  Depositional environment

  The formation contains exclusively marine sediments, representing deposition on a shallow marine shelf.
