Beskrivelse
Knurr Formation
NameFrom the fish species Eutrigla gurnardus (grey gurnard). The formation corresponds to T4-1 or Slettnes Formation of earlier informal terminology.Well typeWell 7119/12-1 (Statoil), coordinates 71°06'08.00"N, 19°47'40.29"E, from 2497 m to 2441 m (Fig 4.51) .Well reference sectionWell 7120/12-1 (Norsk Hydro), coordinates 71°06'48.7"N, 20°45'20.1"E, from 1660 to 1375 m. A core was taken between 1535 and 1546 m in this well (Fig 4.50) .Thickness56 m in the type well and 285 m in the reference well.LithologyIn the type well the formation consists of dark grey to greyish brown claystone with thin limestone and dolomite interbeds. Thin sandstones are also seen in the unit's lower parts, but these disappear laterally into the Hammerfest Basin. Red to yellow brown claystone generally occurs in the upper parts of the formation.Basal StratotypeThe base is defined by decreasing gamma ray response and by the sonic log showing decreasing interval transit time. In the type well the density log response shows a slight decrease in an otherwise increasing trend across the boundary. However, the general pattern in most wells is an increase in the density log response accompanying the sonic log response. The base is marked by a thin sandy limestone in the reference well.Lateral extent and variationPresent data suggest similar lithologies in all wells which penetrate the formation. The sand content is somewhat higher close to the Troms-Finnmark Fault Complex (e.g. well 7119/12-1 ). Most complete sequences are seen along basin margins.AgeDinoflagellates and foraminifera suggest a Ryazanian/Valanginian to early Barremian age.Depositional environmentThe formation was deposited in open and generally distal marine environments with local restricted bottom conditions.CorrelationThe formation is a lateral equivalent of the dark shale dominated Rurikfjellet Member of the Janusfjellet Formation on Svalbard.Source-
