Tympaki basin has been studied in the past years from a hydrogeological point of view. Whatsoever, lessare known on the subsurface structure of the plain part of the basin in terms of sediments thicknesses andfaults existence. A way of identifying in-ferred faults is the integrated use of geophysical and well-datawhich finally give an insight of the subsurface within a content of a well-established knowledge of thegeo-logical regime of the study area. In this paper the use of 3D geological modelling technique isdescribed as a mean to identify fault structures and horizon depths. The data used include the digitalelevation model (DEM) of the area, the boundary sur-face between geologic formations and the lithostratigraphicdata from wells, geo-physical measurements of Vertical Electrical Soundings (VES) andTransient Electro-magnetic Method (TEM). The first step was to develop a 3D stratigraphic model thatapproximates the subsurface position of the Plio-Quaternary and the Neogene depos-its. The inferredfaults came out from this model were cross-checked with the TEM measurements providing an updatedsubsurface structure. All the newly identified faults and along with the depth of stratigraphic horizons givefinally an overall tecton-ic pattern of the Tympaki basin.
