A large-scale VES survey was conducted at the NW part of the Amynteon basin in order to study the tectonic setting of the area. Sixty-four soundings (AB/2= 1000 m) were measured on a near-regular grid and were processed with 1-D inversion algorithm. Several parameterisation patterns were tested before producing the final interpretations. Since the measured soundings centres are situated on a regular grid it was possible to combine the 1-D interpretation results and produce pseudo-2D and 3D depth slices. Interpretations are in very good agreement with the existing drilling and geological information and reveal a relatively detailed picture of the basin’s geological background. Further the results allowed us to verify the continuation of known faults and to obtain new structural information about the studied area. The results indicate that despite the increased use of 2D electrical surveys, 1-D VES measurements are still a very useful tool for large-scale applications.
