| Tartalmi kivonat: | The mineralogy of the Nile Delta coastal sediments has been examined. This study summarizes the results of mineralogical examinations of 13 profiles collected along the coast. Each profile contains breaker zone, beach, backshore zone and dune samples. The distribution of the translucent heavy minerals in the coastal environmental sands suggests that there are four characteristic suites among the four provinces, generated by the hydrodynamic forces affecting the coast. The interconnections between hornblende and both garnet+ ZTR reveal negative correlations. These relationships can be used to differentiate between coastal environments. Three explanations are offered for the higher concentration of the heaviest minerals in the Burullus beach sands than in the beaches near Rosetta and Damietta: a) contributions from offshore old sediments of classic Nile branches rather than the present Nile, b) contributions from the land itself, and c) minerals have a good chance of being concentrated during coastal erosion. |
