In the study area of the eastern Gulf of Guinea continental margin slope, offshore Nigeria, turbidite depositional systems are confined to slope-valley and slope-basin bathymetric lows bounded by densely faulted, structurally complex zones. Each depositional system consists of three architectural segments (in order): (1) upper slope, small-scale channel elements converging downslope, (2) single channel and nested channel elements with linear to sinuous map patterns, grading further downslope (3) slope-basin lobe and sheet elements. Incised channels and constructional levees indicate transport by turbulent flow. Comparison of the mapped seismic amplitude patterns of different sequences suggests switching of the inferred sand-prone turbidite systems from one slope valley to another through time. This is interpreted to reflect both the lateral shifting of the fluvial sediment supply on the shelf, and the local tectonic modification of slope-valley geometry.
