Abstract:
Alluvial deposits within the Sabaloka Gorge and the Sixth Cataract, the Nile River, Sudan, represent a set of deposits with a high lithological variability. This is due to the geomorphology and short-time and intensive flood events resulting in aggradation and erosion of the alluvial zone. Human maintenance of the alluvial zone also plays a role. Therefore, these sediments seem to be ideal for a methodological case study to show how the lithological facies differ depending on the sedimentary dynamics of the river. Non-magnetic proxies together with TOC values depend on magnetic properties characterized by magnetic susceptibility and its frequency dependence.
