Abstract The present study was carried out on three exploited mines: ElShaghab, Um-Tundab and Um-Hagara sections in Wadi El-Shaghab, ElSibaiya East area, Nile Valley, Egypt. These mines are located between longitudes 33o7` and 33o16` E and latitudes 25o15` and 25o20` N (Figs. 1 and 2). The studied area is considered as an essential part of Qena-Idfu region. This region is bounded from the east by a highly dissected mountains, while from the west it is bounded by low topographically limestone plateau. Structurally, faulting represent the main tectonic event in the area, (Hermina, 1972). This region can be described as a part of huge NW monocline which was disturbed by two sets of NNE-SSW faults. These faults gave rise to a series of step faults or shallow grabens and horsts, (El-Naggar, 1966). The faults in the area are essentially of the normal type with distinct dragging. These faults resulted in pronounced displacement on the eastern side of the Nile Valley where Duwi Formation appears against the Dakhla shale (Philobbos, 1969). |
