profile. Increased rates of basinward tilting and
structuring during the Maastrichtian to Ypresian
resulted in yet another change into a stepped to
mildly ponded slope profile. As argued below,
stepped or terraced slope topography is favoured
above a distinctly ponded slope profile (Fig. 3).
Moreover, a lower slope environment is supported
as the most probable setting for the Ormen Lange
turbidite system (Smith & Møller, 2003), in con-
trast to Gjelberg
et al
. (2001, 2005), Martinsen
et al
. (2005) and Sømme
et al
. (2009), who favour
an inner basin-floor setting.
the Turonian to Coniacian Lange and Lysing
Formations (Fugelli & Olsen, 2005; Martinsen
et al
., 2005) and the Upper Maastrichtian to Danian
sandstones of the Springar Formation and Egga
sandstone unit (Gjelberg
et al
., 2001, 2005; Smith &
Møller, 2003; Sømme
et al
., 2009), respectively
(Fig. 2). The stratigraphic nomenclature applied
here is the formal Mid-Norway lithostratigraphy of
Dalland
et al
. (1988), in accordance with Smith &
Møller (2003) but in contrast to Gjelberg
et al
.
(2001, 2005), who favoured the northern North Sea
lithostratigraphic scheme.
The Maastrichtian to Palaeocene succession
along the Møre Margin has been re-evaluated
biostratigraphically and a fully integrated and con-
sistent biozonation of all wells in the eastern Møre
Basin has been produced (Fig. 2B). An important
outcome of this exercise was the re-dating of the
Maastrichtian and Palaeocene stratigraphy
The Upper Cretaceous to Lower Palaeogene basin-
fill of the Møre Basin is overall mud-prone, with
the exception of some sandier intervals such as

Well correlations of the Maastrichtian and Palaeocene succession in the eastern Møre Basin. (A) Dip profile (line
A on index map) from the upslope Slørebotn Subbasin to the Ormen Lange subbasin forming a downslope terrace. (B) Strike
profile across the upslope Slørebotn Subbasin (line B on the index map). The correlations are flattened on Base Palaeocene.
Stratigraphic positions of flooding surfaces (FKs and FTPs) are shown in Fig. 2.
