GEOLOGICAL FEATURES IDENTIFIED FROM FIELD OBSERVATIONS AND REMOTE SENSING DATA ON THE UM TAGHIR AREA, EASTERN DESERT, EGYPT

The current study presents the integration between field observations and remotely sensed data for detection extraction of geological structural features using Sentinel-2A Aster DEM images. area under investigation is represented by Neoproterozoic East African Orogeny encompassing a part Arabian Nubian Shield. All rock units studied belong to Late Cryogenian-Ediacaran periods that are divided into two large terrains (continental arc terrain oceanic terrain). metagabbro metavolcaniclastic rocks make up terrain, while gabbro, tonalite, granodiorite, dokhan volcanic, monzogranite alkali feldspar granite comprise continental terrain. remote sensing ASTER have meaningful application in respect interpretation. Lineament analysis one most useful tools mapping mineral exploration. Several methods processing extracting lithological information lineaments were applied covering present study. include various image enhancements (FCC, MNF PCA) directional filters (Sobel). results show was subjected stresses directions (WNW – ESE, NW-SE, NE-SW, N-S, NNE SSW, E-W). There occurred some important structure-related mineralization events like migmatization (in granodiorites) bearing gabbro), which associated with major elements evidence-based control proximity Quena Safaga shear zone-related mineralization.
