The basement rocks around Baranis-Aswan Road, South Eastern Desert of Egypt encompasses a variety of the oldest Pan-African rock units including medium-grade hornblende schist, a variety of gneisses and migmatite as well as medium- to low-grade metavolcanics. These were intruded by syn- to late-tectonic tonalite, granodiorite, quartz diorite as well as gabbros. The exposed basement rock units in the area were discriminated with the detailed lithological mapping using the processed data of ASTER, Landsat-8 and Sentinel-2. Spectral signatures of these rocks were achieved by ASD TerraSpec Halo mineral identifier device. Petrography and geochemistry data enabled to put constraints on their petrogenesis. Geochemically, the schist and gneisses imply K-poor mafic igneous precursors that were developed in a primitive juvenile oceanic environment. The migmatite pertains to stromatic type, whereas granitic magma (neosome) was injected in hornblende schist (paleosome) through cleavage planes. The syn-tectonic tonalite to quartz diorite are also low-K, non-mature calc-alkaline rocks and pertain to oceanic plagiogranite. They display a continuous fractionation evolution trend from quartz-diorite to tonalite and granodiorite.

埃及东南沙漠 Baranis-Aswan 路周围的基底岩石包含各种最古老的泛非岩石单元，包括中品位角闪石片岩、各种片麻岩和混合岩以及中低品位变质火山岩。这些被同构造到晚构造的英云闪长岩、花岗闪长岩、石英闪长岩以及辉长岩侵入。使用 ASTER、Landsat-8 和 Sentinel-2 处理后的数据，通过详细的岩性绘图识别该地区暴露的基底岩石单元。这些岩石的光谱特征是通过 ASD TerraSpec Halo 矿物识别设备获得的。岩石学和地球化学数据能够限制它们的岩石成因。在地球化学上，片岩和片麻岩暗示了在原始少年海洋环境中发育的贫钾镁铁质火成岩前体。混合岩属于叠层类型，而花岗岩浆（新体）通过解理面注入角闪片岩（古体）中。这同构造闪长岩与石英闪长岩也是低钾、非成熟钙碱性岩石，属于大洋斜花岗岩。它们呈现出从石英闪长岩到英云闪长岩和花岗闪长岩的连续分馏演化趋势。
