Abstract

Manifestations of rock weakness contribute to creating favorable conditions for the activity of erosion factors and weathering processes with their various characteristics, the results of which were the disintegration and fragmentation of rocks to form one of the geomorphological phenomena, which is slope talus. The research aims to shed light on the effect of rock weaknesses on the origin and development of slope talus. Therefore, the aim is not to explain the spatial variation, as it is limited in the study area, for all the rocks in the belong to the Precambrian era. Hence, the main aim is to monitor the weaknesses within the rocks and link their degrees with the most important and first phenomenon that may arise from this weakness, which is the slope talus. The application is carried out on the slopes of both sides of Sharm El-Sheikh-Dahab road, southeast Sinai, due to the spread of this phenomenon in multiple locations, with its diverse morphological characteristics, which helped in identifying how it originated and developed. This is done by making morphometric measurements and terrain profiles of talus covers and cones, and studying the various rock units, in addition to conducting physical, chemical, and microscopic analyzes of selected samples from each rock unit.
