Evaluation of quaternary aquifer between qena and luxur. (Nile Valley, Egypt)
MetadataShow full item record
In order to evaluate the hydrogeological setting of the Quaternary aquifer and the related geological structures controlling its characteristics. A total of 50 vertical electrical soundings (VES.s) were conducted along 13 profiles covering the area between Qena and Luxur. As revealed from the present study, the Quaternary section in the area is subdivided into four main geoelectrical zones distributed irregularly in the study area: Zone (A) with very high electrical resistivity values ranges between 950 and 49300 ohm-m. and thickness between 1.5 and 40.6 m. This zone is interpreted as gravely one. Zone (B) is characterized by electrical resistivity values ranges between 34.8 and 558 ohm-m. and depths between 0.48 and 36.9 m. and is formed of sand and gravels. Zone (C) has electrical resistivity values ranges between 2.5 and 17.7 ohm-m. and depths between 1.3 and 18 m., is formed from Nile silt. Zone (D) represents has electrical resistivity values range between 17.2 and 97 ohm-m. depths between 6.6 and 297 m. This zone represents the water-bearing layer of Qena - Dandara Formation. A low resistivity zone with resistivity values ranging between 1.21 and 6.5 ohm-m. and usually extends to the maximum depth of penetration is detected (Dakhia Shale). Another water bearing aquifer layer with resistivity ranging between 7.4 to 35.6 ohm.m.(Nubia sandstone) underlying Dakhia Shale Formation.
