英文摘要	The Wadi Faliq El Sahl-Faliq El Waar area comprises four various types of rocks including metavolcanics, older granites, Hammamat sediments, and younger granites of monzogranite and syenogranite composition. From the various structural analyses in the investigated area, the main trends controlling the structural and tectonic framework are ENE-WSW and NE-SW, while the trends NNE-SSW, WNW-ESE, and N-S are less abundant. Three major phases of deformation are detected in the study area, each of which gives its specific trends according to the applied stress axis during the time of deformation. The first phase shows compressive stress whose sigma 1 maximum compressional axis was E-W trend (N81 degrees W). The second phase is a compression phase in which the sigma 1 maximum compression axis was directed N13 degrees W. The third phase represents a trans-tensional (extensional) stress system, in which the maximum tension force (sigma 1) is in the N-S trend. The study area passed through four stages of evolution, which are (1) the arc-metavolcanic formation with island arc assemblage and the intrusion of older granitoids during the inter-collision of the island arcs; (2) the tectonic processes forming the inter-mountainous basins; (3) the folding of the Hammamat basin under Najd-related shear zones; and (4) the intrusion of syenogranite and uplifting of the Hammamat sediments during the Late Precambrian rifting. The potash-rich outer zone of pegmatite bosses in the younger granites recorded high values of gamma radioactivity with U content.
