Abstract

The eastern margin of the central Gulf of Suez comprises the elongate Neoproterozoic basement rocks of Gabel Durba-Araba and Gabel Ekma, which represent sedimentary cover ranging in age from Palaeozoic to Quaternary sediments. Lineaments, a form of geological structure, have risen in popularity recently in geological investigations. It is a widely used structural and geological indicator for establishing general and local tectonic tendencies and fracture zones in rocks, especially in areas covered by basement and sedimentary cover. The global digital elevation/surface model (DEM/DSM) and PLASAR radar data were utilized to distinguish the various structural lineaments' orientation, morphological characteristics, and relationships with distinct tectonic stages exposed in the research region. This data was used for detecting and mapping surface and near-surface structure lineaments. The statical method in the mean of lineament detecting, frequency, length, and density distribution was analyzed using ArcGIS 10.5, PCI Geomatics, and Rockwork 16. Analyze and interpret data related to the different tectonic episodes exposed to the study area. Based on the age of the host basement rift blocks and the overlaying sedimentary cover, we found four population lineament trends. NW and NNE to NE represent the main populations of lineaments affected in the study area. These altered lithological rocks from the Precambrian basement to the Tertiary sediments represent the main structural fault that controls the Gulf of Suez Rift. Other trends represented by WNW and ENE were observed, most probably because of repeated reactivation of tectonism along pre-existing deep structural discontinuities, which are crustal fracture zones.
