| Tartalmi kivonat: | The textural characteristics of the Nile Delta coastal sands from the nearshore zone, breaker zone, beach, backshore zone, coastal dunes and River Nile were studied. A consistent difference exists between the coastal environments from the point of view of the bivariant scatter plots, the shape of log-probability curves and CM diagrams. This information has been used as an aid in determining the depositional environments of some unknown borehole sand deposits. The study of the vertical, change for each unit of borehole sediments can be considered as a tool for reconstructing the depositional history and shoreline changes of the Nile Delta coast. It is indicated that the shoreline of the central part of the Nile Delta coast has advanced and marine sediments (nearshore zone, breaker zone, beach) with a thickness of 22 m have been laid over the backshore flat area. The false impression of many studies may be connected with the comparison of unknown sediments from one area with known sediments from another area. |
