Mineralogical characteristics of the Western Nile delta coast sediments
In this paper, results of 3 years of heavy mineral investigations are presented. Fourteen annual nearshore profile samples were collected along the coast between Rosetta and Burullus. Each profile includes backshore, beach and nearshore samples up to 6 m depth. Coastal dune samples from east of Buru...

| Tartalmi kivonat: | In this paper, results of 3 years of heavy mineral investigations are presented. Fourteen annual nearshore profile samples were collected along the coast between Rosetta and Burullus. Each profile includes backshore, beach and nearshore samples up to 6 m depth. Coastal dune samples from east of Burullus are also studied. The sediment of the Rosetta headland are characterized by the greatest concentration of heavy minerals. It declines in the central part and then relatively increases towards Burullus. The heaviest minerals decrease normal to the shoreline while the lighter ones increase. High concentration of the heavy mineral at Rosetta and Burullus sediments may be related to: (1) Contribution from offshore old sediments of classic Nile branches rather than the present Nile. (2) Contribution from the land itself, where the dunes and backshore contain great amount of these minerals. (3) These minerals are concentrated during severe coastal erosion. |
