Abstract This paper presents a reconstruction of the palaeodrainage evolution of the Niger River in West Africa in order to contribute to the understanding of sediment supply to the Niger Delta. It has been covered extensively in literature that the Niger River has undergone changes along its course in the Holocene, as implied by the large bend it makes in Mali. However, other enigmatic bends further downstream are indicative of an older and more complicated history that has yet to be understood, and is the focus of this paper. Until now, sediment supply from the Niger River has been considered as being negligible compared to that of the Benue River. The results of this study imply that the contribution from the Niger River was more important than previously thought. The Niger River obtained its present-day geometry in three phases: a Bida Basin phase (Maastrichtian–Miocene); a Iullemmeden Basin phase (Miocene–Pleistocene); and a present-day Niger River phase (Holocene). In the Miocene, an important capture event occurred, increasing the incipient drainage basin by 10 6 km 2 , thereby changing the provenance of the sediment supplied to the Niger Delta from mainly crystalline basement to mixed lithologies including sandstone, shale, limestone and volcanic outcrops.

Overview map and numerical model setup. Southern Africa (SAf) is held fixed in present-day position in all reconstructions. A: Lambert azimuthal equal area view of pre-rift configuration at 140 Ma, showing major rigid plates and deforming crustal regions (Heine et al., 2013). Present-day South America and Africa plates are separated into four major rigid plates in region of interest during Late Jurassic–Early Cretaceous: NEA—northeast Africa, NWA—northwest Africa, SAf—southern Africa, SAm—South America. Rift systems (white font, red background): CARS—Central African rift, EqRS—Equatorial Atlantic rift, SARS—South Atlantic rift, WARS—West African rift. Red and white polygon indicates map frame (in B), white dashed lines are present-day 5° graticule. B: 117 Ma reconstruction (Heine et al., 2013). Northernmost segment of SARS is already in seafloor-spreading mode; in EqRS, breakup is incipient. Numerically modeled region is indicated by white rectangle. Minor rigid plates: BPB—Borborema province block (northeast Brazil), Jos—Jos subplate (northern Nigeria), SLC—São Luis craton. Basins (B): BarB—Barreirinhas Basin, BeT—Benoue Trough, FdA—Foz do Amazon Basin, G.G.—Gurupi graben, IuB—Iullemmeden Basin, MarB—Marajó Basin, MB—Maranhão Basin, PotB—Potiguar Basin. C: Initial geometric setup of three-dimensional numerical model involves prospective rift zones as thermal heterogeneities. Model size is 2400 × 1600 km horizontal and 200 km vertical. LAB—lithosphere-asthenosphere boundary. D: Lithospheric segment is vertically divided into four distinct petrological layers, upper crust, lower crust, lithospheric mantle, and asthenospheric mantle. Rheological parameters (see the Data Repository [see footnote 1]) of crust are chosen to represent narrow rift setting as supported by crustal architecture along conjugate equatorial margins (Azevedo, 1991). Rheology of lithospheric and asthenospheric mantle is based on laboratory creep measurements for dry and wet olivine, respectively.
