“…templates, such as tortuous corridors (Smith, 2004a;Hay, 2012), mini-basins (Booth et al, 2003;Beaubouef and Abreu, 2006;Madof et al, 2009;Pirmez et al, 2012;Prather et al, 2012b;Oluboyo et al, 2014;Doughty-Jones et al, 2017), and piggy-back basins/foredeep margin slopes , and/or do not span multiple large-scale sea-level cycles (e.g., Beaubouef and Abreu, 2006;Barton, 2012). Moreover, these studies do not investigate the long-term stratigraphic evolution of slopes nor characterize stratigraphic architecture at a scale that resolves relationships between sedimentary processes and seabed topography.…”

“…These units were deposited at a time of lower sediment supply, with deposition commencing on a more deformed slope after the D-D/E transgressive and highstand sequence set sand shut-off. Units D/E, E1, F1, and F2 were deposited in intraslope accommodation, with E2, E3, and F3 deposited in healed slope accommodation (sensu Prather, 2003) where they evolved to "fill and overspill" accommodation to bypass sediment down-dip (e.g., Prather et al, 1998;Beaubouef and Friedmann, 2000;Pirmez et al, 2000;Booth et al, 2003;Barton, 2012;Bohn et al, 2012).…”

The effects of abrupt changes in slope angle and orientation on turbidity current behavior have been investigated in numerous physical and numerical experiments and examined in outcrop, subsurface, and modern systems. However, the long-term impact of subtle and evolving seabed topography on the stratigraphic architecture of deep-water systems requires fine-scale observations and extensive 3-D constraints. This study focuses on the Permian Laingsburg and Fort Brown formations, where multiple large sand-rich systems (Units A-F) have been mapped from entrenched slope valleys, through channel-levee systems, to basin-floor lobe complexes over a 2500 km 2 area. Here, we investigate three thinner (typically <5 m in thickness) and less extensive sand-rich packages, Units A/B, B/C, and D/E, between the large-scale systems. Typically, these sand-rich units are sharp-based and topped, and contain scours and mudstone clast conglomerates that indicate deposition from high-energy turbidity currents. The mapped thickness and facies distribution suggest a lobate form. These distinctive units were deposited in similar spatial positions within the basin-fill and suggest similar accommodation patterns on the slope and basin floor prior to the larger systems (B, C, and E). Stratigraphically, these thin units represent the first sand deposition following major periods of shut-down in sediment supply, and are interpreted as marking a partial re-establishment of sand delivery pathways creating "disconnected lobes" that are fed mainly by flows sourced from failures on the shelf and upper slope rather than major feeder channel-levee systems.Thickness and facies patterns throughout the deep-water stratigraphy suggest seabed topography was present early in the basin formation and maintained persistently in a similar area to ultimately form a stepped slope profile. The stepped slope profile evolved through three key stages of development: Phase 1, where sediment supply exceeds deformation rate (likely caused by differential subsidence); Phase 2, where sediment supply is on average equal to deformation rate; and Phase 3, where deformation rate outpaces sediment supply. This study demonstrates that smaller systems are a sensitive record of evolving seabed topography and they can consequently be used to recreate more accurate paleotopographic profiles.

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.

“…The revealed facts that sediment waves a) can be not only confused with but be complicated by creep processes [Mitchell&Huthnance, 2007], b) are evidence for present or past active environment, e.g. turbid flows, trigging, gas eruption [Putans et al, 2010], c) due to lithologically sorted material can be small-scale reservoirs both for free gas and fluids [Wynn et al, 2007, Booth et al, 2003], lead to assumption that presence of these geofeatures may be direct indicator of "geological state that represents or has the potential to develop further into a situation leading to damage or uncontrolled risk" e.g. geohazard.…”
