A high sinuosity, laterally migrating submarine fan channel-levee-overbank: results from DSDP Leg 96 on the Mississippi Fan, Gulf of Mexico

A Process Model for the Evolution, Morphology, and Architecture of Sinuous Submarine Channels

“…To date, the best documented example of submarine meander development and migration comes from the youngest mid-fan channel of the Mississippi Fan Shor 1985, 1986;Stelting et al 1985a;Pickering et al 1986). Channel-development reconstructions are based on high-amplitude reflectors (HARs) from seismic-reflection profiles, interpreted as PROCESS MODEL FOR SINUOUS SUBMARINE CHANNELS coarse-grained channel-axis facies.…”

Sinuous deep-water channels: Genesis, geometry and architecture

“…It is perched upon a broad levee system, some 50 km wide and 200 m high; crevasse splays are present on outer bends in some places. Slope angles in this section vary between 0.51 and 0.251 (Bouma et al, 1984(Bouma et al, , 1985aShor, 1985, 1986;Pickering et al, 1986). Early seismic-based studies provided information on the cross-sectional morphology of Mississippi Channel (Stuart and Caughey, 1976;Moore et al, 1978) but, as with Amazon Fan, it was not until planform mapping of the fan surface was undertaken with GLORIA sidescan sonar, that the sinuous nature of the channel was fully revealed (Garrison et al, 1982;Shor, 1985, 1986;Wen et al, 1995).…”

“…It covers an area of at least 300,000 km 2 , has a volume of at least 290,000 km 3 , and is over 600 km long (Fig. 4); it was constructed rapidly during the Plio-Pleistocene, and is covered by a thin veneer of Holocene pelagic/hemipelagic sediments (Bouma et al, 1984(Bouma et al, , 1985a(Bouma et al, , b, 1989Feeley et al, 1985;Pickering et al, 1986;Twichell et al, 1991). Sedimentation rates were as high as 6-11 m per 1000 year during Pleistocene glacials (Kohl and DSDP Leg 96 Shipboard Scientists, 1985;Stelting et al, 1985), with the ancestral Mississippi River being the dominant feeder system (Huang and Goodell, 1970;Davies, 1972).…”

Interactions between submarine channel systems and deformation in deepwater fold belts: Examples from the Levant Basin, Eastern Mediterranean sea

“…Many of these settings are affected by thin-skinned gravitational collapse, and are characterised by coeval sedimentation and deformation. Submarine channel systems are commonly described from such settings, examples include the Niger Delta (Deptuck et al, 2003;Adeogba et al, 2005;Heinio and Davies, 2007), the Gulf of Mexico (Posamentier, 2003;Pickering et al, 1986) the Nile Delta (Samuel et al, 2003), Brunei (Demyttenaere et al, 2000) and Offshore West Africa (Gee and Gawthorpe, 2006;Abreu et al, 2003). Submarine channels are also recognised from accretionary prisms located at subduction zones, examples include the Barbados Accretionay Prism (Huyghe et al, 2004), The Kuril Arc (Noda et al, 2008), the Central Chile Forearc (Hagen et al, 1994) and the Nankai Trough (Soh and Tokuyama, 2002).…”
