The main problem in mineral exploration is how to determine the existence of deposits at subsurface based on resistivity and chargeability parameters. Clay almos exixts in rocks Here, this study was to understand the influence of clay on time domain induced polarization. To clarify the clay parameters, filed physycal modelling data of 20 cm diameter sphenical target with a total content of 28,3% of iron did not show any significant response. The high content of clays on the medium used in field physical modelling seem to be the mean reason for the change in sample. In the case of the subsurface sperical model that is near to the soil medium, the presence of clay lead to the medium resistivity value to be identical to the target value. As a consequence, the resistivity response can not be identifiedn clearly. The Chargeability between the medium an the target remains small but the chargeability response remains constant.
