Subsurface structural delineation and mineralisation potential from integration of aeromagnetic and remote sensing datasets in Gabal Abu Rahaya area, South Eastern Desert, Egypt

Abstract

This study investigates the subsurface geological structures and mineralisation zones in the Gabal Abu Rahaya area, South Eastern Desert, Egypt, using integrated geological, remote sensing, and aeromagnetic data. Landsat-8 imagery was processed to identify lithological contacts and fault zones, creating a refined geological map of the region. Aeromagnetic data were analysed using geophysical filters such as Reduced-to-Pole (RTP), Tilt Derivative (TDR), Centre for Exploration Targeting (CET) porphyry analysis, and Euler deconvolution to delineate subsurface structural features and mineralisation patterns. The results from both remote sensing and magnetic data showed consistent structural trends, including matching fault and contact zones, which significantly improved the reliability of structural interpretations. This data integration enhances the delineation of prospective mineralised zones, making it possible to refine geological models for the area. The approach successfully combines satellite imagery and aeromagnetic data, offering a useful methodology for mineral exploration in complex, poorly mapped regions. Ultimately, the study provides a model for targeting ore deposits in similar geologically challenging terrains, contributing to more accurate mineral exploration.
