4D forward stratigraphic modelling of the Late Quaternary Congo deep-sea fan: Role of climate/vegetation coupling in architectural evolution

Width variation around submarine channel bends: Implications for sedimentation and channel evolution

“…The architecture and timing of avulsion of the channel-lobe systems on the Axial Fan have been connected to climatic factors controlled by the West African monsoon. During humid periods, river discharge increases and the fan progrades, whilst during arid periods the fan retrogrades (Picot et al, 2019;Laurent et al, 2020). Babonneau et al (2002).…”

Middle to late Pleistocene palaeoceanography inferred from ridge-furrow structures on the continental slope offshore Angola

“…Over the late Quaternary, the channel-levee-lobe systems has undergone lateral architectural changes of increasing/decreasing channel lengths and basinward/landward migration of avulsion points, corresponding to prograding/retrograding architectural fan cycles (Marsset et al, 2009;Picot et al, 2016). Studies of the Axial Fan show that climatic factors controlled by the West African monsoon are the primary control of architecture and timing of avulsions of the channel-levee-lobe systems (Laurent et al, 2020;Marsset et al, 2009;Picot et al 2016Picot et al , 2019. During the humid period, the progradation system occurs with high fluvial discharge and chemical erosion, elevating the transport capacity of the turbidity currents (Marsset et al, 2009;Picot et al 2016Picot et al , 2019.…”
