Description
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Name From a submarine slope north of Vannøy around 70°40'N, 19°40'E. The unit corresponds to T6 or Nordkapp Group of earlier usage.
Type area Block 7119/12.
Thickness The group shows a general increase in thickness from approximately 300 m near the southern margins of the Hammerfest Basin, to approximately 1 km in the most sorthwestern wells in the basin.
Lithology The group is dominated by claystones, with only minor siltstone, tuffaceous and carbonate horizons.
Basal Stratotype The base of the constituent Torsk Formation is defined by changes in sonic and density log responses. The basal contact is unconformable and represents an important depositional break in the latest Cretaceous and early Paleocene throughout the Tromsøflaket area.
Lateral extent and variation Due to a shift in tectonic regime in the middle Oligocene, large areas of the Barents Shelf east of the Senja Ridge were uplifted and subjected to erosion, which lasted until the early Pliocene. The erosional products were deposited west of the ridge. As a result of this postdepositional erosion, the upper part of the Sotbakken Group is not preserved in the eastern parts of Tromsøflaket. The lower parts are probably present throughout the Barents Shelf, but younger sequences are only preserved over the Ringvassøy -

Tops and cored lengths are the Directorate's, per wellbore and unit; the percentiles are computed from those tops and are depths along the wellbore, not true vertical depth.
