“…The results presented here regarding the Middle Jurassic-Early Cretaceous tectonostratigraphy of the Dutch offshore complement the already extensive knowledge of the interval in the North Sea (Andsbjerg & Dybkjaer 2003;Fraser et al 2003;Wonham et al 2014). The article by Verreussel et al (2018) applies knowledge of the Dutch Sector northwards to the offshore German and Danish sectors and, despite being primarily focused on the stratigraphic framework of this larger area, should be considered alongside this work to fully understand the tectonostratigraphic evolution of the entire failed rift system.…”

The Middle Jurassic-Lower Cretaceous in the eastern Dutch offshore provides excellent examples of sand-rich sediments that locally accumulated in the vicinity of rift basin margins affected by salt tectonics. These types of deposits are often geographically restricted and difficult to identify, but can be valuable targets for hydrocarbon exploration. The distribution, thickness and preservation potential of fluvio-lacustrine, shallow-and deep-marine sediments is discussed to provide new insights into the regional and local tectonostratigraphy of the Dutch Central Graben, the Terschelling Basin and their neighbouring platforms. New sedimentological, geochemical, biostratigraphic, stratigraphic and structural information have been analysed and integrated into a new tectonostratigraphic model for the Callovian Lower Graben Formation, Oxfordian Middle and Upper Graben formations, Early-Middle Volgian Terschelling Sandstone and Noordvaarder members, and the Late VolgianEarly Ryazanian Scruff Greensand Formation. It is demonstrated that salt withdrawal at the basin axis was the primary control on the generation of high accommodation during the Callovian-Early Kimmeridgian. Incised valleys developed on the platforms providing lateral sediment input. During the Late Kimmeridgian-Ryazanian salt migration shifted laterally towards the basin margins, providing accommodation adjacent to active salt bodies and deposition of overthickened sandy strata.

“…Mandal High) (Ziegler, 1990;Gowers et al, 1993;Fraser et al, 2003). Shallow marine clastics (Ula Formation) followed by deep marine mudstones (Haugesund and Farsund Formations) were deposited in fault-controlled depocentres and in subbasins that developed over collapsed salt walls (Hodgson et al, 1992;Gowers et al, 1993;Smith et al, 1993;Mannie et al, 2014;Wonham et al, 2014). A second phase of rifting is interpreted to have occurred from late Kimmeridgian to early Volgian (Berriasian) and is associated with overall sediment starvation that led to the deposition of organic-rich mudstones (Mandal Formation) (Gowers et al, 1993;Rattey & Hayward, 1993;Erratt et al, 1999).…”

Studies of salt‐influenced rift basins have focused on individual or basin‐scale fault system and/or salt‐related structure. In contrast, the large‐scale rift structure, namely rift segments and rift accommodation zones and the role of pre‐rift tectonics in controlling structural style and syn‐rift basin evolution have received less attention. The Norwegian Central Graben, comprises a complex network of sub‐salt normal faults and pre‐rift salt‐related structures that together influenced the structural style and evolution of the Late Jurassic rift. Beneath the halite‐rich, Permian Zechstein Supergroup, the rift can be divided into two major rift segments, each comprising rift margin and rift axis domains, separated by a rift‐wide accommodation zone – the Steinbit Accommodation Zone. Sub‐salt normal faults in the rift segments are generally larger, in terms of fault throw, length and spacing, than those in the accommodation zone. The pre‐rift structure varies laterally from sheet‐like units, with limited salt tectonics, through domains characterised by isolated salt diapirs, to a network of elongate salt walls with intervening minibasins. Analysis of the interactions between the sub‐salt normal fault network and the pre‐rift salt‐related structures reveals six types of syn‐rift depocentres. Increasing the throw and spacing of sub‐salt normal faults from rift segment to rift accommodation zone generally leads to simpler half‐graben geometries and an increase in the size and thickness of syn‐rift depocentres. In contrast, more complex pre‐rift salt tectonics increases the mechanical heterogeneity of the pre‐rift, leading to increased complexity of structural style. Along the rift margin, syn‐rift depocentres occur as interpods above salt walls and are generally unrelated to the relatively minor sub‐salt normal faults in this structural domain. Along the rift axis, deformation associated with large sub‐salt normal faults created coupled and decoupled supra‐salt faults. Tilting of the hanging wall associated with growth of the large normal faults along the rift axis also promoted a thin‐skinned, gravity‐driven deformation leading to a range of extensional and compressional structures affecting the syn‐rift interval. The Steinbit Accommodation Zone contains rift‐related structural styles that encompass elements seen along both the rift margin and axis. The wide variability in structural style and evolution of syn‐rift depocentres recognised in this study has implications for the geomorphological evolution of rifts, sediment routing systems and stratigraphic evolution in rifts that contain pre‐rift salt units.

“…In his discussion of Drake field, Stuart (2003) described offshore-transition zone facies often characterised by an abundance of Rhaxella, within the lower portion of his "coarsening-upwards (or at least cleaningupwards)" cycles, rather than at the top of a cycle, as suggested by evidence from well 22/5b-A10. In contrast, Wonham et al (2014) suggested that in the North Sea Central Graben: "The spicule-rich zone belongs predominantly to the retrogradational part of the shoreface progradational-retrogradational cycles".…”

“…The Fisher Bank Basin forms the northernmost part of the North Sea eastern Central Graben (Fig. 1), and Jurassic sediments were deposited here in response to a eustatic rise in sea-level, superimposed on a complex background of rifting, subsidence, fault-block tilting and salt movement (Clark et al, 1993;Wonham et al, 2014). Oil and gas-condensate fields in this area include the Armada Complex (Fleming, Drake and Hawkins fields), the Seymour field, and the Maureen, Maria and May fields located approximately six miles to the NW (Fig.…”
