The Induced Polarization method, a well known tool for sulphide exploration and indirectly for gold searching in pollymetalic associations is experiencing also an increasing application in underground water exploration and civil engineering problems. A review on the basic theory, applicabilities, field methodologies, advantages and disadvantages is presented. The aim of the present study, however, is to develop a methodology for IP analog modelling. The choice was for simple geometric shapes such as cylinder and thin sheets, built with quartzitic sand and disseminated graphite in a standard cement. The grade of graphite was controlled and varied for different model geometries. The results are discussed in terms of IP response as a function of geometry, graphite content, depth and strike of the models.
