The Wadi Sa'al-Wadi Zaghara area, southern Sinai, Egypt is a key geologic region within the framework of the Arabian-Nubian Shield (ANS). It almost documents the whole tectono-thermal evolution history of the Pan-African orogeny; hence it records the latest stages of Rodinia breakup (Late Mesoproterozoic) till the penultimate regional deformation event (D₃) that impacted the northern tip of the ANS in the Late Neoproterozoic, i.e., before the Najd fault system. Since the metamorphosed volcano-sedimentary rock units in both Wadi Sa’al and Wadi Zaghara exhibit considerable differences in their geological evolution, they were dealt with as two distinct metamorphic belts. They cover a wide spectrum of basement rock varieties, which developed over a long period of time, from Late Mesoproterozoic (Wadi Sa’al metamorphosed volcano-sedimentary rocks) till Late Neoproterozoic Ediacaran period (post-collision granites). The different rock units of the study area were discriminated based on various image processing techniques such as Decorrelation Stretch (DS) Band Ratio (BR) and Principal Component (PC) of Sentinel-2, Landsat-8 and ASTER datasets. Remote sensing data analyses with the aid of petrography, previously published data and field verification enabled us to produce a new enhanced geological map of the study area. Advanced Land Observing Satellite (ALOS) digital elevation and enhanced Sentinel-2, Sobel directional filter images were successfully used for automatic lineaments extraction in the study area.

埃及西奈半岛南部的 Wadi Sa'al-Wadi Zaghara 地区是阿拉伯-努比亚地盾 (ANS) 框架内的关键地质区域。它几乎记录了泛非造山运动的整个构造热演化历史；因此它记录了罗迪尼亚分裂的最新阶段（晚中元古代），直到倒数第二次区域变形事件（D ₃) 在晚新元古代，即在 Najd 断层系统之前影响了 ANS 的北端。由于 Wadi Sa'al 和 Wadi Zaghara 的变质火山沉积岩单元在地质演化上表现出相当大的差异，因此将它们视为两个不同的变质带。它们涵盖了从晚中元古代（Wadi Sa'al 变质火山沉积岩）到晚新元古代埃迪卡拉纪（碰撞后花岗岩）的广泛基底岩品种。基于 Sentinel-2、Landsat-8 和 ASTER 数据集的去相关拉伸 (DS) 带比 (BR) 和主成分 (PC) 等各种图像处理技术来区分研究区的不同岩石单元。借助岩相学进行遥感数据分析，先前公布的数据和现场验证使我们能够制作研究区域的新增强地质图。先进陆地观测卫星 (ALOS) 数字高程和增强型 Sentinel-2、Sobel 定向滤波图像成功用于研究区的轮廓线自动提取。
