The integration of remotely sensed data allowed the successful characterization of the hydrothermal alteration zones of the Abu–Gaharish area in the Central Eastern Desert of Egypt using image transformation techniques. The integration of several evidential maps highlighted the plausible areas with high concentrations of argillic and phyllic, key hydrothermal minerals that reflect the intensity of hydrothermal effects and the probable sites of ore bodies. The excellent prospective zone identified in the map occupies around 1.39% of the study area. Kaolinite–smectite minerals with correlation scores of around 0.97 were consistent with areas of hydrothermal alteration and mining activities; however, propylitic minerals were confined to basic metavolcanics and serpentinites. The resulting predictive map was assessed using existing mining data with significant consistency; therefore, field verification is essential. The overall results showed that remotely sensed data represent a valuable mapping tool for geological and mineral resources reconnaissance in the arid regions

遥感数据的整合使得能够利用图像转换技术成功地描述了埃及中部东部沙漠地区阿布－加哈里什地区的热液蚀变带。几个证据图的整合突出显示了可能的区域，其中富含反映了热液作用强度和矿体可能位置的重要的热液矿物，即藻土和页岩。地图上确定的极好的预期区占研究面积的1.39％。高岭石-蒙脱石矿物的相关评分约为0.97，与热液蚀变和采矿活动的区域一致。但是，丙炔矿物质仅限于碱性超火山岩和蛇纹岩。所产生的预测图是使用现有的挖掘数据进行的，具有高度一致性的评估；因此，现场验证至关重要。总体结果表明，遥感数据代表了干旱地区地质和矿产资源勘察的宝贵测绘工具
