Investigating geothermal resources in the Central Eastern Desert of Red Sea, Egypt, using aeromagnetic data

This research delves into the unexplored geothermal resources within Egypt’s internationally significant Red Sea and Central Eastern Desert regions, recognized for their renewable energy prospects. Surface thermal manifestations in granitic rocks, abundant in radioactive minerals, and geothermal anomalies along the depocenter regions of the Red Sea rift highlight the medium to high geothermal resources in the area. Utilizing an extensive dataset of aeromagnetic data, including derived heat flow (HF) data, geothermal surveys, and radioactive analysis of granitic rock samples, this study employs cutting-edge geophysical methodologies, particularly aeromagnetic data analysis, to identify the structural trends of the study area. The results reveal a range of medium to high heat flow values, determined through meticulous examination of the Curie depth point, temperature gradient, and HF data. Comparative analysis with seismicity data and the structural framework unveils distinct geothermal sources, setting this region apart within Egypt. The observed correlation between high-seismicity areas, structural locations, and HF map locations suggests a significant role of geodynamic motions in shaping the heat flow patterns. By highlighting the substantial geothermal potential, this study underscores the importance of advanced geophysical data in accurately identifying potential energy sources. The insights derived from this research hold global relevance, providing guidance for future exploration and development initiatives and contributing to the international discourse on transitioning to renewable energy. However, a comprehensive evaluation that incorporates radioactive analysis and exploratory drilling is crucial for fully unlocking the geothermal potential in this strategically important study area.
