Abstract
The metamorphic rock units and the magmatic rock units constitute their two primary assemblages at southeast Aswan area. The metamorphic assemblage consists of migmatites, gneisses, and hornblende schist. The magmatic rocks comprise two categories: monzogranite and garnetiferous muscovite monzogranite. Schist, migmatite, and gneiss are great examples of rocks that have folded. Granitic rocks invade the metamorphic rock assemblages before being covered by Nubian Sandstones. According to the Landsat 8 results, we concluded that the FCC (6, 5, 4) and (7,6,5), plus band ratio images (3/5, 3/1, 5/7), (7/5, 5/4, 3 /1), (6/2, 6/7, 6/5 * 4/5) , PCA (PC321, PC421, and PC721) bands and Supervised classification was applied, with maximum likelihood (ML) and support vector machine (SVM) are the best attempts to separate the different rock units in this region. The maximum likelihood results for OLI data show well lithological discrimination between the rock units with an overall accuracy of 98.26% and Kappa Coefficient 0.9741.
