Abstract | ||||
Airborne magnetic dataset at Wadi El Nakhil area was processed to estimate the basement depth, and consequently the thickness of the sedimentary cover which may provide some insights into the groundwater potentiality at the study area. The corrected aeromagnetic data is represented by total magnetic intensity (TMI) was reduced to the magnetic pole (RTP). The radially averaged power spectrum technique (RAPS) and source parameter imaging technique (SPI) were used to estimate the depths to basement. The radial power spectrum technique showed that average depth of the isolated short wavelength anomalies is 9.23 m, and the depth of the long wavelength anomalies is 1587.21m whereas the SPI technique showed that the depth to basement ranges from 53m to 1500 m. In particular, the southeastern and northwestern parts of Wadi El Nakhil are characterized by a thick sedimentary cover of 385 and 1300m, respectively. These parts with thick sedimentary cover may represent areas or include horizons with high groundwater potentiality. | ||||
