Fig. 3. Central North Sea biostratigraphic scheme showing schematic long term retrogradational stratigraphy of sequence sets J50 to J70. This figure has been
adapted after Partington et al . (1993b), retaining only data from the Central Graben. Sequence boundary locations proposed by Partington et al . are indicated
with names based on the colour scheme of Donovan et al . (1993) and the SJU sequence boundary naming scheme of Veldkamp et al . (1996). Relationship of
named sequence boundaries to named MFS follows that given by Veldkamp et al . (1996). Brown, Yellow and Green sequence boundaries were not shown
on the original figure of Partington et al . from which this figure is adapted. Dating of the Fulmar Sst of the Fulmar Field is from Kuhn et al . (2003). Dating
of the Gyda Sandstone of the Fulmar Field is from Partington et al . (1993a) and dating of the Franklin Sst is from Lasocki et al . (1999) and subsequent stud-
ies. Seismic horizons interpreted by this study are also indicated. The turbidite sandstone marked 'Shearwater' is the turbidite sandstone lying immediately
above shoreface sandstones in the 22/30b-11 well (as described by Jeremiah and Nicholson, 1999).
