Aeromagnetic data of the western part of Koraimat-Alzafarana road, Eastern Desert, Egypt is interpreted to detect the subsurface structures that may resulted in presence of subsurface aquifer. To reach to the main target of this study, many procedures are done using some magnetic analysis techniques (e.g., technique of reduction to the magnetic pole, separation technique of regional-residual anomalies and edge detection methods). The results have been encouraging to merit further estimation of the magnetic depth and analyzing the trends of the study area. To increase the credibility, the depth is revised by the P-depth technique. The shallow and deep magnetic components are calculated to be 2046 and 5680 m. To ease the detection of the structure that encasing the study area and lack the rigorous analysis, reduced the magnetic pole map, residual map and 3D Euler deconvolution are integrated to depict the combined lineament map that prevailing tectonic pattern of the study area. Eventually, NE-SW trend is the predominant structural trend affecting on the study area as deducing from magnetic anomalies. Moreover, there are minor structural trends which were taken N-S, NW-SE, W-E, NNW-SSE and NNE-SSW directions. The presence of subsurface structures may assist in the occurrence and recharging of the groundwater aquifers.
