英文摘要	Old gold mines in the Barramiya district, Eastern Desert of Egypt, are associated with NE-SW-trending ophiolitic ultramafic belts and their alteration zones (listvenitization). This paper integrates geophysical aeromagnetic and geological studies, including remote sensing technologies, to explore the potential for planning future development of gold mining in Barramiya, Central Eastern Desert (CED), Egypt. Utilizing remote sensing techniques and processed Landsat-8 images is valuable and successful in delineating the distribution of ophiolitic ultramafic belts with their associated alteration zones. Moreover, aeromagnetic data analyses were carried out to reveal the subsurface geologic setting, the extent with depth and the possible association with gold mineralization. The total intensity map was examined numerically for remanent magnetization content using the normalized source strength transformation (NSS) for proper delineation of the mineralization with depth. The reduced-to-pole map was subjected to a variety of digital filters and tomographic inversions. The results reveal the association of three previously productive gold mines with clear low magnetic anomalies and consequently low magnetic susceptibility in the Barramiya mine area and Um Slim. However, numerous new similar anomalies were recognized and need to be explored for possible gold mineralization. The estimated depths to magnetic sources using the 3D Euler technique range between 143 and 1125 m, while 506.7 m was the estimated average depth to sources. Such results suggest other possible locations and deep gold mineralization in the areas corresponding to low magnetic susceptibilities. These results agree well with the constructed geologic map, and the spatial distributions of different rock units were classified according to distinctive mineral assemblies of serpentinites and their spectral characteristics to improve their identifications.
