    Kolje Formation

    Name
    From the fish species Melanogrammus aeglefinus (haddock). The formation corresponds to T4-2 and T4-3, the Tamsøy and Anda formations of earlier informal terminology.
    Well type section
    Well 7119/12-1 (Statoil), coordinates 71°06'08.00"N, 19°47'40.29"E, from 2441 m to 2004 m (Fig 4.52) .
    Well reference section
    Well 7120/12-1 (Norsk Hydro), coordinates 71°06'48.7"N, 20°45'20.1"E, from 1375 m to 1272 m (Fig .53) .
    Thickness
    437 m in the type well and 103 m in the reference well.
    Lithology
    Dark brown to dark grey shale and claystone dominate, with minor interbeds of pale limestone and dolomite. The upper part of the formation also has thin interbeds of light grey-brown siltstone and sandstone. The reference well displays similar lithologies.
    Basal Stratotype
    The base is marked by gradually decreasing gamma ray, decreasing interval transit time and increasing density log responses in the type well. However, in the central part of the Hammerfest Basin the density log response shows a decreasing trend at the formation base. A marker in the middle part of the formation (boundary between unit T4-2 and T4-3 of earlier informal terminology) shows an increase in density in parts of the Hammerfest Basin. An increasing gamma log response is associated with this log break westwards. The log breaks at the base and in the middle parts of the formation are thought to reflect condensed intervals providing important regional seismic markers.
    Lateral extent and variation
    The formation thickens westwards but thins towards the central part of the Hammerfest Basin. There are no marked regional variations in lithology.
    Age
    An early Barremian to late Barremian/early Aptian age is suggested.
    Depositional environment
    The formation was deposited in distal open marine conditions, with good water circulation, but also with periodic restricted environments.
    Correlation
    The formation is a lateral equivalent of the Helvetiafjellet Formation, a distinctive sand-dominated unit on the Svalbard Platform.
