Fig. 15 Interpretation of minor and major structures (Ibraheim et al. 2019) along E-W profile
overlain regional aeromagnetic map confirming the 3D resistivity model of Fig. 14 where the horst
and graben structures are common in the area
Fig. 16 Relationships between formation resistivity, water resistivity and TDS of Taref aquifer:
(a) The estimated empirical relationship between formation resistivity and water resistivity, (b)
The obtained relationship between TDS and formation resistivity (c) Formation resistivity distributions from surface resistivity measurements, (d) Water resistivity distributions from laboratory
measurements of Ec e) TDS distribution from water samples
