Kimmeridgian and Volgian fault-margin sedimentation in the Northern North Sea area
… from a relatively shallow water and sand-rich submarine slope during the early Kimmeridgian to a deeper water sediment starved submarine slope during the early Volgian. The sediments of the South Brae Oilfield were deposited in the channelised part of a submarine fan system which was sourced …

Sequence stratigraphy and structure of the tertiary limestones in the Gulf of Papua,Papua New Guinea
… reef, shoal, forereef, basin margin and submarine fan facies. Each facies was differentiated according to seismic character and geometry, well core and cuttings descriptions, and its position in the depositional framework of the sequence. Deposition of the Mendi Limestone Megasequence …

Role of Froude supercritical flow in active margin basin-floor fans, The
… focuses on the active margin basin floor fan and tests the hypothesis that whether Froude supercritical flow and a high degree of channelization are common features in basin floor fans, even in a distal part. The Froude supercritical flow may control the architecture and characteristics of …

The Skiddaw Group of Cumbria : early Ordovician Turbidite sedimentation and provenance on an evolving microcontinental margin.
… sandy shelf or delta) was present Two periods of submarine fan development display the following facies associations: depositional lobe, lobe fringe and interlobe, distributary channel, and proximal channel-levee. The first spans the Tremadoc-Arenig boundary and channels distributed sediment to …

Sedimentology of a Lower Middle Pleistocene Reservoir in Garden Banks Area, Northern Gulf of Mexico: Integration of 3D Seismic, Cores, and Well Logs
… Pimento, is part of a lower middle Pleistocene submarine-fan deposit in the north central Gulf of Mexico. Pimento field represents a classic example of a prograding fan across the continental shelf continuing across the continental slope filling and spilling minibasins. Channel complexes cut …

Aspects of the structure, tectonic evolution and sedimentation of the Tygerberg terrane, southwestern Cape Province
… is consequently assigned to the lower and mid fan parts of a prograding submarine fan model.

Fluid flow through connected sub-seismic features in mudstone
… shale unit, deposited in the distal zone of a submarine fan, was studied to investigate the controls on fluid flow through low permeability clastic rock. Turbidite flows are present within the shale as very thin (1-5mm) fine grained sandstone beds, channels and lenses which would not be picked …

Basin Evolution and Slope System Dynamics of the Cretaceous Magallanes Basin, Chilean Patagonia
… or alteration ofsediment source terrains leave submarine basin deposits as the only record of the tectonic and cli-matic forcings that govern the transfer of sediment to the deep basin. The overarching goal of thisdissertation is to evaluate controls on submarine slope and basin-floor …

Climatic and tectonic controls on deep water sedimentary cyclicity : evidence from the Miocene to Pleistocene of Cyprus
… derived clasts in the Khirokitia-Psematismenos submarine fan-complex. Here,graphic logging, and biostratigraphy suggests that the six cycles observed are likely to correlate to cycles identified in European sequence chronostratigraphy, though higher frequency,climatic cyclicity is obscured by …

Geology and Tectonic Significance of the Late Precambrian Eastern Blue Ridge Cover Sequence in Central Virginia
… rocks. These are believed to be channelized submarine fan turbidites formed in an anoxic environment. Lynchburg ill consists of fine to medium grained feldspathic quartz arenites and a minor amount of conglomeratic rocks, which are considered to be channelized submarine turbidites with a more …

Stratigraphic evolution and architectural analysis of structurally confined submarine fans: a tripartite outcrop-based study
… different structurally confined, distributive submarine fans: the Eocene Guaso I turbidite system, Ainsa basin, Spain, and the Miocene upper Modelo Formation, eastern Ventura basin, California. In Chapter 2, geologic mapping, paleocurrent measurements, architectural analysis, and correlation of …

Accurate AVO modelling and reservoir characterisation of the upper cretaceous deepwater reservoirs in the Vøring Basin.
… reservoirs formed by deep-marine slope and submarine fan type environments (Morton et al. 2004). The associated facies vary from thick sheet sands to thin channels and shale rich lobes (Goodall et al. 2002). Avseth et al. (2011) suggest that geological data from wells can be linked to the …

Seismic stratigraphy and tectonic evolution of a transform continental margin, offshore Sierra Leone
… and the development of extensive lowstand submarine fan systems. Some models of slope failure and synchronous development of submarine channel and canyon systems have been developed for this basin. Extensional slope failure is controlled by pre-existing structural trends. Submarine canyons …
