“…A major northwest-trending Najd shear zone (the Rihba shear zone: length 50 km; width 200 m; Fig. 1a) that extends in our study area was reported (Moustafa 1997;Bosworth and McClay 2001;Younes and McClay 2002;Sultan et al 2012).…”

“…The sinistral slip (post-Early Miocene to Recent) on the Dead Sea Transform and associated drag on the eastern edges of preexisting east-west-to east-northeast-west-southwest-oriented faults could have resulted in simple dextral wrenching (Moustafa and Khalil 1994). Also, a transtensional origin for these dextral faults was proposed, where the throw along the Gulf of Suez rift-related northwest-southeast-oriented faults could have caused Late Oligocene to Early Miocene divergent dextral wrenching along preexisting faults (Moustafa and Khalil 1994;Moustafa 1997;Younes and McClay 2002).…”

An integrated [very low frequency (VLF) electromagnetic, magnetic, remote sensing, field, and geographic information system (GIS)] study was conducted over the basement complex in southern Sinai (Feiran watershed) for a better understanding of the structural controls on the groundwater flow. The increase in satellite-based radar backscattering values following a large precipitation event (34 mm on 17-18 January 2010) was used to identify water-bearing features, here interpreted as preferred pathways for surface water infiltration. Findings include: (1) spatial analysis in a GIS environment revealed that the distribution of the water-bearing features (conductive features) corresponds to that of fractures, faults, shear zones, dike swarms, and wadi networks; (2) using VLF (43 profiles), magnetic (7 profiles) techniques, and field observations, the majority (85 %) of the investigated conductive features were determined to be preferred pathways for groundwater flow; (3) northwest-southeast-to north-south-trending conductive features that intersect the groundwater flow (southeast to northwest) at low angles capture groundwater flow, whereas northeast-southwest to east-west features that intersect the flow at high angles impound groundwater upstream and could provide potential productive well locations; and (4) similar findings are observed in central Sinai: east-west-trending dextral shear zones (Themed and Sinai Hinge Belt) impede south to north groundwater flow as evidenced by the significant drop in hydraulic head (from 467 to 248 m above mean sea level) across shear zones and by reorientation of regional flow (south-north to

“…1b). These shear zones are oriented WNW, oblique to the NNW rift trend, and were reactivated during the Miocene rifting (Moustafa, 1997;Khalil and McClay, 2001;Younes and McClay, 2002). Fracturing is well developed in the basement, Fig.…”

“…During the Red Sea rifting, the E-W faults are considered to be accommodation zones between the tilted fault blocks (Cochran and Martinez 1988;Moustafa 1997). Dextral wrenching with transtension of the E-W faults was noted by Moustafa and Khalil (1994) and Moustafa and Abd-Allah (1992).…”

The basement rocks, Neogene sediments and Quaternary alluvial deposits in the Abu Dabbab area, Eastern Desert of Egypt, are deformed by N-S, NE-SW, NW-SE and E-W trending faults. Complex cross-cutting relationships show a complicated history of initiation and reactivation of these faults. The recent fault scarps demonstrate different morphologies, modes of formation and relative ages. Recurrent, step and successively reactivated faulting was likely responsible for the exhumation and neo-formation of the fault scarps. Capture, deep incision, offset and reversal in flow direction of streams are the main drainage modifications induced by active faults. The concealed and active faults are associated with high drainage density anomalies. Segmentation phenomenon is common for all fault trends. Microearthquakes are concentrated at the intersection zones of faults and caused by upper crustal strike-slip, oblique-slip, reverse and normal faults. The paleostresses are not consistent with the present-day stress fields. The present-day NE-SW extension across the Red Sea combined with a local multidirectional tension led to reactivation of old faults and initiation of new fault trends.
