Abstract | ||||
The primary objective of this study is to assess the inversion structure and specific structural components utilizing high-quality 2D seismic lines obtained from the Horus oil field. This field is situated in the southern section of the Alamein Basin, positioned above the hanging-wall of a normal fault from the Jurassic-Early Cretaceous period. This fault extends in an ENE-WSW direction and bounds half graben trough in the northern margin of Horus oil field. Cretaceous period appears NE-asymmetrical anticline overlying Jurassic rifting. The movements of the tectonic belts resulted in a regional extensional regime during the Jurassic and Early Cretaceous periods. Subsequently, stress movements during the Late Cretaceous to Oligocene period led to the inversion of the Alamein Basin. Numerous NW-SE oriented normal faults, varying in length and throw, dissect the Cretaceous horizons. These faults partition the anticline into multiple blocks. The inversion of this basin is ascribed to the Syrian-Arc event, which prevailed over North Africa at the Late Cretaceous period. | ||||
