f IP Image Profiling - 2D Inversion of Resistivity and Chargeability

Recently, two-dimensional resistivity inversion techniques have been widely used for mineral resource exploration, ground water exploration, and civil engineering purposes (for example Shima, 1990). On the other hand, induced polarization (IP) method has been used mainly for the metal resource exploration. Chargeability obtained by the IP method corresponds to the polarization or charging phenomenon of underground which usually caused by metal ores or clay minerals. The IP method is considered effective to explore clayish fracture zone for the civil engineering purposes. Joint inversion of resistivity and chargeability data is also expected to have better accuracy than conventional roversion of only resistivity (Iseki and Shima; 1992).
