A combination of geophysical methods could be very a useful and a practical way of verifying the origin and precise localisation of archaeological situations identified by different remote sensing techniques. The results of different methods (and scales) of monitoring these fully non-destructive methods provide distinct data and often complement each other.

Resistivity surveys are made to satisfy the needs of two distinctly different kinds of interpretation problems (1) the variation of resistivity with depth, reflecting more or less horizontal stratification of earth materials; and (2) lateral variations in resistivity that may indicate soil lenses, isolated ore bodies, faults, or cavities. For the first kind of problem, measurements of

Our Advanced Resistivity Scanner (ARS) allows you to look for metals with discrimination (gold, copper, silver, iron), gold veins, minerals, caves/voids and even water. This is achieved through resistivity analysis. Resistivity is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current. READ MORE

Resistivity and Electrical Conductivity

Resistivity is also important in power distribution systems as the effectiveness of the earth grounding system for an electrical power and distribution system greatly depends on the resistivity of the earth and soil material at the location of the system ground. Conduction is the name given to the movement of free electrons in the form of an electric current. Conductivity, σ is the reciprocal

The edited xy apparent resistivity and phase is shown in Figure 6 while the yx apparent resistivity and phase is shown in Figure 7. Note that in both cases, the phase is by comparison very smooth and self-consistent as compared to the apparent resistivity. The phase low (in blue) at approximately 500 Hz in Figure 6 is due to silicified carbonates of the Ronning Group, which show a clear dip to
