Description
Fuglen Formation
NameFuglen lighthouse is situated on the western tip of Sørøy at 70°40'N and 21°55'E. The unit corresponds to T3-1 or Risfjord Formation of earlier informal schemes.Well type sectionWell 7120/12-1 (Norsk Hydro), coordinates 71°06'48.7"N, 20°45'20.1"E, from 2047 m to 2019 m (Fig 4.50) . The lowermost 5 m and the contact with the underlying Stø Formation are cored in this well.Well reference sectionWell 7119/12-1 (Statoil), coordinates 71°06'08.00"N, 19°47'40.29"E, from 2658 to 2610 m (Fig 4.51) .Thickness28 m in the type well and 48 m in the reference well.LithologyPyritic mudstones with interbedded thin limestones give characteristic gamma, sonic and density log responses. The shales are dark brown and the limestones white to brownish grey.Basal StratotypeThe lower boundary is marked by sharp increases in gamma ray and density responses and by an accompanying decrease in interval transit time.Lateral extent and variationThe formation is thickest in southwestern parts of the Hammerfest Basin, thinning to less than 10 m on the central highs in the basin; these areas are characterized by rare, thin limestones and by pyritic shales.AgeLate Callovian to Oxfordian.Depositional environmentThe formation was deposited in marine environments during a highstand with ongoing tectonic movements. Coarse clastic sources were not emergent, but local block structures were the sites of low sedimentation rates.Source-
