  Fiskebank Formation
  
  Name

  From the Fiskebank (Fisher Bank), off the shore of southern Norway. Named by Deegan & Scull (1977).

  Well type section

  Norwegian well 9/11-1 from 1483 m to 1335 m, coordinates N 57°00'41.40", E 04°00'33.52" (Fig 5.54) . No cores.

  Well reference section

  Norwegian well 8/9-1 from 1399 m to 1307 m, coordinates N 57°26'27.28", E 03°51'03.48" (Fig 5.55) . No cores.

  Thickness

  The formation is 148 m thick in the type well and 92 m thick in the reference well.

  Lithology

  In the type section the major lithology is very fine grained, well sorted, slightly silty sandstone, which occasionally has calcareous cement.

  Basal stratotype

  The basal contact of the Fiskebank Formation is defined by the boundary between the shales of the Lista Formation and the coarser sediments of the Fiskebank Formation. The difference between the two formations is not well defined on the logs. The boundary is placed where the gamma-ray readings decrease and the velocity increases somewhat upwards into the Fiskebank Formation (Fig 5.54, 5.55)

  Characteristics of the upper boundary

  The Fiskebank Formation is overlain by the shales of the Balder Formation . The boundary is generally seen as an upward decrease in gamma-ray response and an increase in velocity (Fig 5.55) .

  Distribution

  The formation is encountered in the Norwegian-Danish Basin.

  Age

  Late Paleocene.

  Depositional environment

  The formation is probably a basin-margin deposit, and appears to be mostly time-equivalent with the Sele Formation .
