“…Additionally, it is affordable and includes both local and regional investigations. The magnetic method has primarily been used for regional surveys in hydrocarbon exploration (Abdelazeem et al 2020(Abdelazeem et al , 2021De Smet et al 2020;Abdelrahman et al 2019;Gobashy and Al-Garni 2008;Al Garni et al 2006); engineering geophysics (Araffa et al 2021;Azeem et al 2014); groundwater exploration (Gobashy et al 2021b); mineral exploration (Gobashy et al 2022(Gobashy et al , 2021aEl-Sawy et al 2018;Abdelrahman et al 2019); and mapping geological structures and igneous intrusions (Al Garni et al 2012;Wang et al 2017); in addition, estimating sedimentary basin thickness and identifying groundwater contamination (Nazih et al 2022;Rehman et al 2019) and geologic hazard and risk assessments (Fergany et al 2014;Al Garni and Gobashy 2010) are examples of a such wide range of applications.…”

The construction of the New Galala City besides great mining (e.g., konoozmisr) and Seawater Reverse Osmosis Desalination Plant projects in the semiarid Gulf of Suez region of Egypt increases the demand for groundwater resources. So, the current research provides integrated stratigraphical, hydrogeochemical, and geophysical studies to investigate the shallow groundwater aquifers in Wadi Araba area on the western side of the Gulf of Suez. The stratigraphic column starts with pre-Cambrian basement rocks which are non-conformably overlain by sedimentary succession of Phanerozoic Erathem. A detailed land magnetic profile has been conducted and processed to estimate the aquifer’s geometrical parameters. This includes the subsurface spatial extension and thickness to delineate the prevailed subsurface structures in the study area. Lithostratigraphically, these aquifers are represented by the Paleozoic- lower Cretaceous siliciclastic-dominated sediments of the Nubia Group and fractured carbonate-dominated facies of the upper Cretaceous Galala Formation. Lithological characters, sedimentary facies (fluvial to shallow and open marine), microfacies types, and diagenesis processes (e.g., compaction, cementation, dissolution, and fracturing) are the main factors that affect the quality of the shallow aquifers in the study area. The main microfacies of the studied aquifers are quartz arenite, subarkose, sublitharenite, mudstone/wackestone, and packstone/grainstone. These facies are characterized by different primary and secondary porosities. According to the water sampling standard methods, nineteen groundwater samples were collected from the available hand-dug wells and springs from the Nubian sandstone aquifer and the Upper Cretaceous aquifer, respectively. Inductively coupled plasma–mass spectrometry (ICP–MS), titration, spectrophotometer and a flame photometer were used to obtain a complete chemical analysis. The results of hydrochemical analyses indicated that total dissolved solids (TDS) and concentrations of major ions as well in the lower Cretaceous aquifer increase toward the Gulf of Suez and in general higher than that of springs of the Upper Cretaceous Aquifer. The predominant factors influencing groundwater chemistry include seawater intrusion, evaporation, mineral alteration, dissolution of fossils, and ion exchange. Groundwater in the study area is unsuitable for drinking except in one sample and moderately suitable for irrigation with caution for higher salinity in samples located near the Gulf of Suez.

“…El Moghra Oasis and its vicinities locate in the north Western Desert; about 40 km south of El Alamein (Figure 1(a)). It extends between latitudes 30°00'-30°25' N and longitudes 28°20'-29°20' E. The gravity data can be used for delineating the subsurface structures and defining the depth of basement rocks to locate the basins which can be referred to as the best locations for oil accumulation (Sultan et al 2009;Araffa et al 2014Araffa et al , 2015Abdelazeem et al 2020Abdelazeem et al , 2021. The target of the current study aims to determine the basins which can be occupied by oil potentiality or water and faults controlling the subsurface sequence (Abdelazeem et al 2020).…”

El Moghra area represents a vital part of the national reclamation area at the northern part of Western Desert, Egypt. Delineating subsurface structures (faults & basins) and depth to the basement is the base of planning the area. Basins can be water aquifers or oil traps. Gravity data has been used to tackle such aims. The gravity (Bouguer) anomaly map is separated into regional components (deep sources), and residual component (shallower sources). The residual gravity map was used to delineate subsurface structural features dissecting the investigated area. Also, Euler deconvolution and Tilt Derivative methods have been used for delineating the structural elements. The gravity interpretation indicates that the most main tectonic have E-W, ENE-WSW, and N-S trends for the major structures, while the minor structures are aligned in NNE-SSW, NE-SW, NNW-SSE, and NW-SE. The results of depth estimation using 2D and 3D modelling show that the eastern and southwestern parts of the area under study exhibit a deep basement structure, reaches more than 7000 m (basin). However, the central and northwestern parts of the investigated area show shallower depth of basement rocks (4100 m).
