英文摘要 | Remote sensing and aeromagnetic data provided significant information for detecting potential areas of mineralization in Wadi Allaqi in the South Eastern Desert of Egypt. Application of band ratios and Crosta technique of Principal Component Analysis (PCA) using Landsat-8 successfully highlighted the hydro thermal alteration zones and the structural elements represented by lithologic contacts and faults/fracture zones. Structural lineaments were also successfully extracted using remote sensing and aeromagnetic data. Center for Exploration Targeting (CET) Grid analysis and CET Porphyry Analysis techniques were applied for constructing the structural complexity heat map and probable near circular features of porphyry intrusions respectively. Combining data of lineaments, alteration zones and porphyry intrusions after obtaining a consequence of each map allowed predicting and mapping areas of probable high mineral resources. Overlaying the present sites of mineralization on the final map validated the prepared mineral predictive map. Overall results clearly revealed that areas of high structural complexity, fractures/faults density are in agreement with the detected areas of hydrothermal alterations which also matched with the known mineralization mines in the study area.
