  Garn Formation
  
  Name

  From the Norwegian word for a net. The unit corresponds to the upper part of the Tomma Formation (H1-4) of informal usage, or “Tomma I”.

  Well type section

  Well 6407/1-3 (Statoil), coordinates 64°52'25.48"N, 07°02'53.47"E, from 3704 m to 3600 m (Fig 4.20) . The lower 84 m of the unit are cored, including the base.

  Well reference section

  Well 6507/11-3 (Saga Petroleum), coordinates 65°01'59.8"N, 07°30'42.34"E, from 2457 m to 2412 m (Fig 4.16) . The lower 29 m of the unit are cored, including the base.

  Thickness

  104 m in the type well and 45 m in the reference well.

  Lithology

  The Garn Formation consists of medium to coarse-grained, moderately to well-sorted sandstones. Mica-rich zones are present. The sandstone is occasionally carbonate-cemented.

  Basal Stratotype

  The lower boundary is defined by a drop in gamma ray response. In the type well this coincides with an erosional contact at the base of a thin conglomerate.

  Age

  Bajocian to Bathonian.

  Depositional environment

  The Garn Formation may represent progradations of braided delta lobes. Delta top and delta front facies with active fluvial and wave-influenced processes are recognized.

  Lateral extent and variation

  The Garn Formation is encountered across most of Haltenbanken. It may be over 100 m thick on the Halten Terrace, but in structurally high positions the entire unit may be eroded. In the Trænabanken area shaly sediments are lateral equivalents of the Garn Formation sandstones.

  Correlation

  The Garn Formation is time equivalent to parts of the Brent Group in the North Sea, to the lower part of the Vardekløft Formation in East Greenland and to the upper part of the Stø Formation in the Hammerfest Basin.

  Subdivision

  The formation is not subdivided at present although two different units may be identified in the western part of Haltenbanken.
