Geoelectric techniques have been used to detect and define the subsurface stratigraphy and structures around Hibis Temple in Kharga Oasis, Egypt. We used 2D and 3D inversion approaches to interpret the data set obtained from 20 dipole‐dipole resistivity profiles with electrode spacings of 3 and 5 m and lengths between 39 and 85 m. Five vertical electrical soundings, with a maximum array length of 200 m, along a profile crossing the study area were also carried out. A preliminary quantitative interpretation of the vertical electrical sounding curves was achieved using two‐layer standard curves and generalized Cagniard graphs. The final models were obtained by 1D inversion using the results of the manual interpretation as initial models. Model results were used to construct a geoelectric cross‐section that correlated very well with the stratigraphic units. Five geoelectric units were identified: the first (the uppermost) is a high‐resistivity layer consisting of fill deposits (rubble); the second is a muddy clay with moderate resistivity values; the third is also a muddy clay but with decreased resistivity due to the increase in salt content originated by the evaporation of the groundwater seepage; the fourth unit, at a depth of 7–13 m, is a muddy clay saturated with water seepage from the agricultural areas surrounding the temple; the final unit is a more resistive layer corresponding to dry muddy clay. The differences in the groundwater level, and its salt content, correlated with the irrigation activities around the temple. We concluded that the high corrosion potential of the seepage water might be connected with its salt content.

“…Geophysical research offers the possibility of mapping the physical parameters of rocks in the depth range to be explored, using a system of sections at a chosen investigation depth (the resolution is inversely proportional to the investigation depth). By using the geoelectric measurement technology correctly, useful information can be obtained, and the electric resistivity images can be used to clearly show the shape and depth distribution of certain buried artificial objects [3], [11].…”

With the continuous development of multielectrode geoelectrical tomography (ERT) as a geophysical technique, we became able to detect small size targets. In this paper, we present ERT interpretation results obtained at an archaeological site in Szendrő village in northeastern Hungary, where a 17th century fortress once stood. Several historical notes and a collapsed entrance recall the existence of tunnels under the fortress and a water well of uncertain depth. To detect these structures, geoelectrical multielectrode measurements were carried out using conventional and quasi-null arrays. The quasi-null array applies the arrangement of the current (A and B) and potential electrodes (M and N) in a special way, i.e., the electrodes A, M, B, N follow each other in line in special distances from each other. The horizontal sensitivity of the resistivity profiling method using these types of arrays has been proven to be better than that of the Wenner or other conventional arrays. The comparative study aims not just to investigate the archeological features, but to test the sensitivity of the non-traditional quasi-null arrays to these two-dimensional inhomogeneities. As a result, the optimal array can be chosen, and the identification and delineation of shallow structures can be made more reliably. In this paper, we present the very first archeogeophysical field measurements carried out by the gamma quasi null array (γqnull).
