Abstract

The Bir El-Qash area, located in the Central Eastern Desert of Egypt, is characterized by a diverse range of igneous, metamorphic, and sedimentary rocks with ages spanning from the Late Proterozoic to Quaternary. Integration of remote sensing with aeromagnetic data was conducted to generate surface and subsurface structural lineaments. Shaded relief from digital elevation models, principal component analysis of Landsat-8 data, and ALOS/PALSAR images were utilized to create lineament maps. Airborne magnetic data were employed to reveal subsurface characterizations. The study area has undergone various tectonic activities, resulting in complex structures. Multiple fault trends and fractures were identified, including the NW-SE (Red Sea-Gulf of Suez) trend, the NE-SW trending Syrian arc trend, the N-S trending East African trend and the WNW-ESE trend. By analyzing the tectonic features of the Bir El-Qash area, this study provides insights into the geological history and evolution of the Eastern Desert of Egypt.
