The study focuses on the east Uweinat area in the eastern sector of the Saharan continental crust and extends to the Arabian-Nubian basement rocks in the east. This area extends beyond the Egyptian territories, including the northern part of Sudan and the eastern part of Libya. The Saharan continental crust represents a challenge due to its classification as an arid to hyper arid environment and the difficulty of accessing it. The study aims to construct the regional structural framework of the basement complex that has its influence on the overlying sedimentary section, specifically in the part that belongs to the Saharan continental crust of Egypt. Space geophysical data was used, including GRACE, magnetic, SRTM Gravity Recovery and Climate Experiment, Earth Magnetic Anomaly Grid, Shuttle Radar Topographic Mission and geoid data. A qualitative and quantitative interpretation is used to highlight the subsurface geological picture and structure framework. The integration of these data helps to understand the subsurface structural framework and provide insights into the geological evolution of the region. The constructed structural framework map shows the presence of a large basin east of the Uweinat area, mainly sourced from the Nile River and a small amount of rainfall, with geological obstacles preventing water leakage out. The occurrence of the East Uweinat ring complexes and volcanism have both positive and negative impacts and must be taken into account in any systematic natural resources exploration strategy.

Bostonite rocks are widely spread in the Central Eastern Desert (CED) of Egypt, they are found in the form of sills or dykes injected in the Precambrian rocks. Postgeosynclinal (Hammamat) sediments were intruded by Postorogenic bostonites. The study of this area, using ground geophysical methods, aimed at tracking the radioactive mineralization under the surface, based on the possible association of this radioactive mineralization with some other mineralizations such as sulphides. The application of the self-potential survey shows that the highest negative anomalies are associated with the South El-Atshan bostonite sill and its contact zones. The depths to the centres of some selected anomalies range from 5.7 m to 24 m, half-widths oscillate from 6 to 32 m, with shallow dips towards the west and east directions. The horizontal-loop electromagnetic (HLEM) survey, which was conducted using four frequencies, revealed the presence of two conductive bodies. These conductive bodies possess narrow widths and depths, ranging from 25 m to 27 m, dipping towards the west direction with shallow angles of 25° and 40°, respectively. In addition, the induced polarization (IP) profile shows high chargeability values reaching more than 7.9 mV/V at depths starting from about 10 m to about 35 m. This zone corresponds to a high-resistance zone that may reflect a subsurface disseminated mineralization. The integration of the results obtained using the three techniques makes it possible to determine the most appropriate zones for the development of exploration in the area of investigation.

Mineral exploration in the southern Western Desert of Egypt presents several challenges, making the process demanding. This difficulty is due to many reasons, such as complex geology sand dunes, inaccessibility, and environmental conditions. Therefore, the current study was done to overcome some of these barriers in the future. West of Gabal Kamil is one of the areas where iron mineralization is present, but it does not receive as much attention as other areas. Consequently, remote sensing techniques were used in this study because they facilitate the quick and cost-effective mapping of surface geological and mineralogical characteristics. Multiple satellite image processing techniques were employed on Landsat8 OLI data, such as band-ratio, principal component (PC) analysis, and maximum likelihood classification (MLC) methods. The region mainly comprises Precambrian basement rocks, such as gneiss and granite. The discovered iron ore strata are intermingled with gneissic rocks and display a striped pattern oriented toward the northeast. The mineralization bands are affected by folding and shearing, which are related to thrust faulting structural elements. The central part of the investigated area was identified as the most promising zone for detailed field studies, exploration, and upcoming prospecting. This study reveals the effectiveness of Landsat8 OLI image in identifying new iron ore regions and delineating the lithological units. The methods can be successfully used to discover new extractable iron ore deposits in arid landscapes.

Significant copper mineralization are observed to be associated, in most cases, with some radioactive anomalies related to increased uranium and thorium contents in Southern Sinai, Egypt. These mineralizations are related to intense post-magmatic, structurally controlled hydrothermal activities in many localities. Wadi Khosh El-Daba area is one of these locations which is mainly composed of monzogranites dissected by andesite dyke and pegmatite vein. This work deals with the application of ground magnetic and self-potential methods to establish the magnetic sources governing the mineralization, to interpret the significant trends that affected the study area, and to delineate the mineralized zones. The magnetic data were processed, enhanced and interpreted using advanced techniques, such as the first-order vertical derivative (FVD), the tilt derivative (TD), Euler deconvolution (ED), and source parameter image (SPI). The main structural lineaments/contacts that control the distribution of hydrothermal alterations and mineral distributions are oriented to the NW–SE, NE–SW, and NNW–SSE directions. The self-potential (SP) data show that there are numerous mineralized zones; most of them are distributed mainly along the structural lineaments deduced from the magnetic study. The quantitative interpretation revealed that the mineralized bodies are at shallow depths ranging from 5.6 m to 12.7 m, with half-width from 5 m to 13 m. These bodies are shallow to moderate dipping towards the south and north directions. Based on this study an anomaly map is originated to locate the preferred structural elements that may be controlling the mineralization in the area for further future exploration.
