“…An overall relative rise in sea level was also concluded for the Danish sector. Particular to the Danish Central Graben is the asymmetrical infill pattern with westwards-prograding clinoforms that created a shelf along the eastern margin adjacent to the Ringkøbing-Fyn High, and condensed sedimentation along the western margin and in the northern part of the graben (Vidalie et al 2014). The invoked depositional processes are longshore currents in this re-entrant of the North Sea Basin, processes that may also have influenced mudstone sedimentation in other parts of the North Sea Basin at this time.…”

“…Ineson (1993) provided a first sequence stratigraphic interpretation of the Tuxen and Sola formations, based on core and well-log correlations, suggesting a ramp-type morphology. In a seismic stratigraphic study of the Valhall Formation in the southern part of the Danish Central Graben, Vidalie et al (2014) challenged elements of this interpretation, notably through the observation of the presence of clinoforms that provide a proxy of the basin morphology. The broad shelf that developed at this time in the east of the basin formed the substratum for the overlying Tuxen and Sola formations.…”

“…comm.). Although the Valhall Formation has a generally transparent seismic expression, Vidalie et al (2014) demonstrated the presence of a number of basinwards-dipping reflections with clear topsets, foresets and toesets, which are interpreted as clinoforms prograding towards the basin centre from east to west (Fig. 9a).…”

“…The clinoforms show the presence of a shelf, shelf-break and deeper basinal area, and are proof of the underfilled nature of the Early Cretaceous basin. The asymmetrical infill pattern is attributed to longshore currents, depositing in the eastern side of the basin and leaving through the western side (see references in Vidalie et al 2014). Seismic stratigraphic analysis shows the presence of two base of slope onlapping packages interpreted as lowstand systems tracts, and distinguishes six seismic stratigraphic sequences (Vidalie et al 2014).…”

An integrated tectonic and sequence stratigraphic analysis of the Cretaceous and Danian of the Danish Central Graben has led to significant new insights critical for our understanding of the chalk facies as a unique cool-water carbonate system, as well as for the evaluation of its potential remaining economic significance.A major regional unconformity in the middle of the Upper Cretaceous chalk has been dated as being of early Campanian age. It separates two distinctly different basin types: a thermal contraction early post-rift basin (Valanginian–Santonian), which was succeeded by an inversion tectonics-affected basin (Campanian–Danian). The infill patterns for these two basin types are dramatically different as a result of the changing influence of the tectonic, palaeoceanographic and eustatic controlling factors.Several new insights are reported for the Lower Cretaceous: a new depositional model for chalk deposition along the basin margins on shallow shelves, which impacts reservoir quality trends; recognition of a late Aptian long-lasting sea-level lowstand (which hosts lowstand sandstone reservoirs in other parts of the North Sea Basin); and, finally, the observation that Barremian–Aptian sequences can be correlated from the Boreal to the Tethyan domain. In contrast, the Late Cretaceous sedimentation patterns have a strong synsedimentary local tectonic overprint (inversion) that influenced palaeoceanography through the intensification of bottom currents and, as a result, the depositional facies. In this context, four different chalk depositional systems are distinguished in the Chalk Group, with specific palaeogeography, depositional features and sediment composition.The first formalization of the lithostratigraphic subdivision of the Chalk Group in the Danish Central Graben is proposed, as well as an addition to the Cromer Knoll Group.

A new record of carbon isotopes, nannofossil biostratigraphy, gamma-ray and Fe content variations is presented for the upper Campanian of the Adda-3 core, Danish Central Graben, North Sea. The studied interval provides a revision of previously assigned late Coniacian to early Santonian ages. New biostratigraphic data indicate a late Campanian age for the 60 m thick studied interval. The Late Campanian Event (LCE) is well recorded by a 1.5‰ negative excursion in the bulk δ 13 C, along with two stepwise pre-excursion negative shifts (defining the pre-LCE). The amplitude of the LCE appears higher in the North Sea than in other areas as seen from the correlation to Germany, the UK and France. This correlation allows identification of a new 0.4‰ negative excursion (defined as the conica event). Fe and gamma-ray variations are used to calibrate the record with cyclostratigraphy. Fourteen 405 kyr cycles identified in the upper Campanian of Adda-3 can be correlated to North Germany. The compilation of previous results from North Germany and correlation to Adda-3 shows that the Boreal upper Campanian spans a total of 17 cycles each of 405 kyr; that is, 6.885 myr. The duration of the LCE is estimated to be c . 1 myr at Adda-3 and in North Germany.
