Submarine Fans and Their Channels, Levees, and Lobes
, 2018Submarine fans are complex morphological features that develop on the continental slope, rise and abyssal plain, normally at the mouths of submarine canyons. They are constructed principally from the deposits of sediment gravity flows (mainly turbidity currents and debris flows) as terrigenous and shallow marine sediment is redistributed into deeper ...

The full range of turbidite bed thickness patterns in submarine lobes: controls and implications
Journal of the Geological Society, 2013A widely misused criterion to interpret lobe deposits in submarine fan systems at outcrop, and in core and well logs, is a thickening and/or coarsening upward profile. Lobe deposits from the Laingsburg depocentre, SW Karoo Basin, demonstrate that a full range of bed thickness patterns exists within lobes.

Intrinsic controls on the range of volumes, morphologies, and dimensions of submarine lobes
Sedimentary Geology, 2010Submarine lobe dimensions from six different systems are compared: 1) the exhumed Permian Fan 3 lobe complex of the Tanqua Karoo, South Africa; 2) the modern Amazon fan channel-mouth lobe complex, offshore Brazil; 3) a portion of the modern distal Zaïre fan, offshore Angola/Congo; 4) a Pleistocene fan of the Kutai basin, subsurface offshore Indonesia ...

Sediment gravity flows have a propensity to infill lows and build depositional relief, which influences subsequent flows. This flow-deposit interaction is intrinsic to the evolution of submarine fans at a range of scales. A novel approach is presented that assesses the interaction of turbidity currents with a subtle but evolving depositional topography.

Deepwater Systems Reloaded: Advances on our understanding on submarine lobe deposits
2021Submarine lobes are high aspect ratio sand-rich deposits that are fed by turbidity currents and debris flows via channels in deep-marine settings. As a major component of submarine fans, they represent 1) an important archive of palaeo-environmental change, 2) sinks for organic carbon and pollutants, and 3) are also of economic interest.

The Lauzanier area represents the northernmost extension of the Annot Sandstone series and contains deposits between 650 and 900 m-thick. This basin was active from upper Bartonian or lower Priabonian to early Rupelian. It is composed of two superposed units separated by a major unconformity.
