Pre- and post-Messinian deformational styles along the northern Nile Delta Basin in the framework of the Eastern Mediterranean tectonic evolution
Abstract The present work is focused on the structural deformation styles of the pre- and post-Messinian sequences of the Nile Delta Basin. The structural interpretations presented in this study shed critical insight about the evolution of the Nile Delta Basin through pre- and post-Messinian times, provides high reliability about its origin and development in the context of the Eastern Mediterranean tectonic history. The explanation for the seismic data covering three different gas fields (Baltim Field, Temsah Field and North Sinai Field) extend along the northern offshore portion of the Nile Delta Basin revealed significant variations in the deformational styles between the pre- and the post-Messinian sequences. The pre-Messinian rocks were mainly compressed in northwest-southeast direction creating folding-related compressional deformations which gradually decline eastward. The post-Messinian sequence exhibits differences in the deformational models between the examined fields. In Baltim field, it shows extensional features caused by the bulk northeast-southwest extensional deformation. However, in Temsah and North Sinai fields, this post-Messinian succession exposes north–south compressional deformation. These interpreted deformational directions are extremely well-matched with the regional structure configuration of the Nile Delta Basin and the eastern Mediterranean regions.
期刊介绍:
Well-established international journal presenting marine geophysical experiments on the geology of continental margins, deep ocean basins and the global mid-ocean ridge system. The journal publishes the state-of-the-art in marine geophysical research including innovative geophysical data analysis, new deep sea floor imaging techniques and tools for measuring rock and sediment properties.
Marine Geophysical Research reaches a large and growing community of readers worldwide. Rooted on early international interests in researching the global mid-ocean ridge system, its focus has expanded to include studies of continental margin tectonics, sediment deposition processes and resulting geohazards as well as their structure and stratigraphic record. The editors of MGR predict a rising rate of advances and development in this sphere in coming years, reflecting the diversity and complexity of marine geological processes.
