Abstract

Electrical imaging (tomography) is a survey technique developed for the investigation of areas of complex geology where the use of resistivity sounding and other techniques is unsuitable. Electrical imaging involves measuring a series of constant separation profiles with the electrode separation being increased with each successive traverse. Since increasing separation leads to information from greater depth, the measured apparent resistivities may be plotted as a pseudosection, a contoured section, which reflects qualitatively the spatial variation in resistivity in the cross-section. The resulting pseudosection may be modelled using a two-dimensional finite element program and quite complex modelling may be carried out using commercially available software on a PC although the process is quite timeconsuming
