“…In general, the CSD occupies a partition of the unstable shelf area [17], the majority of which extends across the northern part of Egypt (Figure 3). Many rock units are outcropped along the CSD, including Cretaceous, Eocene, Oligocene, Miocene, Pliocene, and Pleistocene-Recent rocks e.g., [18,19]. Structurally, faults play a major role in the architecture of the exposed fault blocks along the CSD which are represented mainly by NW-SE, WNW-ESE and E-W orientations e.g., [20][21][22].…”

The conducted research offers an environmental assessment of municipal waste (MW) using remote sensing (RS), geological, and geophysical datasets. As a test site, the present study aims to characterize one of the largest uncontrolled dumpsites in Egypt. RS data analysis indicates that high temperature values are concentrated at the MW and landfill site allocations as a result of the decomposition process, leading to fire risks. Moreover, the geological and structural data draw attention to the structural-controlled old topography role on MW distributions. Consequently, the dumpsite MW has larger surface quantities near the downthrows of the mapped faults. For MW characterization, geophysical data are acquired to produce2D/3D resistivity models. Because MW has the ability to become soft clay, the municipal organic waste and landfill leachate resistivities are lower than that of municipal solid waste and sandy soils. The geophysical inversion results indicate that the maximum thickness of MW calibrating with the drilled borehole data is 60 m. Furthermore, the estimated MW dumpsite volume is about 42.32 MCM. Accordingly, the MW can be characterized in an accurate qualitative and quantitative manner. Our findings, therefore, help the efforts of uncontrolled dumpsite development and thus contribute to sustainability plans.

“…The cumulative throw of these faults are measured by Khairy and Swidan (1992) attains 610 m. Ali and Khairy (1996) state These faults have a combined horizontal and vertical displacements.The horizontal one is predominant and they transferred the older antithetic and synthetic rejuvenated gravitational faults with different lateral offsets. Henaish (2018) classified the geometry ofthe fault-related domes on the Suez Gulf to domes formed in strike-slip zones or domes formed by drag along normal fault and domes formed at transfer zones of normal faults. Accordingly,The antiform-structural faults in the Ras Budran area may relate to the first and the third types of fault-related dome structures.…”

Ras Budran area is located in the central eastern offshore area of the Suez Gulf. The sedimentary successions from the Paleocene to the Lower-Middle Miocene were chosen to assess in the well EE85-1A at the Ras Budran area.Thegeochemical analysis of the Rock-Eval and vitrinite reflectance was applied for evaluating the studied Formations from the viewpoints of the petroleum systems. From which fifty-four cutting samples represented six Formations of Esna Shale (Paleocene), Thebes (Lower-Middle Eocene), Darat (Upper Eocene), Nukhul, Rudeis (Lower Miocene), and Kareem (Lower-Middle Miocene) were analyzed. The present study distinguishes three different categories of petroleum source potential. The first is very good to excellent source of Thebes Formation has 3.2 wt, % TOC and 22.1 mg HC/g rock of Production yield (Py=S1+S2) on averages. The second is fair sources of the Nukhul, the Darat, and the Esna Shale Formations of averages 1.23, 1.6 and 0.85 wt, % TOC and 1.67, 3.12 and 1.8 mg HC/g rock of Production yield respectively. The third is a poor source of both the Kareem and the Rudeis Formations of averages 1.4, and 0.95 wt, % TOC and 1.5, and 0.92 mg HC/g rock Py. The kerogen types of oil-prone (Type I) and mixed oil/gas prone (Type II) are the main OM (organic matter) constituent of the Thebes Formation of HI (hydrogen index) > 400 mg HC/g TOC and S2/S3 ratio is 6.97 mg HC/g rock on average. The results are categorized the Thebes Formation to be an effective source rock if buried enough to reach the oil window zone. The other Formations of Kareem, Rudeis, Nukhul, Darat, and Esna Shale include kerogens of gas prone (types III) and inert (Type IV) of HI (hydrogen index) < 200 mg HC/g TOC and S2/S3 ratio < 2 mg HC/g rock too.

“…The northern part of the Cairo-Suez District (CSD) is characterized by the presence of extensional folds that are developed in the Paleogene and Neogene sediments (e.g., Gebel (G.) Hamza, G. Oweibed, and G. Nasuri (Henaish, 2018b)). Extensional folds in this study include two geometrical folds: drag folds and transfer folds (Fig.…”

Detailed surface structural mapping of the area positioned in the central northern sector of the Cairo-Suez District (Egypt) was carried out to define the fold geometry and structural evolution of the highly deformed area in an extensional setting. This work is accomplished via field observations of the surface structures and interpretation of the high-resolution satellite images. Stratigraphically, the outcropped rock units are differentiated into four main units and are represented by the Upper Eocene, Oligocene, Lower Miocene, and Middle Miocene formations. Structurally, the Gebel Um Raqm is divided into three main sectors: northern, central, and southern. The northern sector is defined by left-stepping en echelon E-W to WNW normal faults, while the southern sector is delineated by left-stepping en echelon NW-SE normal faults. Moreover, the central sector is characterized by horst-graben faulting styles and step-faults. The structural analysis of the area revealed four main fold trends, which are identified and represented by NW-SE, E-W, WNW-ESE, and NNW-SSE. Also, the major faults are grouped into four main trends and are represented by WNW-ESE, NW-SE, E-W, and NNW-SSE. The interpreted structural geometry of folds and faults indicates that these folds are developed either by the drag of ductile beds along the fault planes as drag folds or formed between the overlapped normal faults as transfer folds.
