Negative induced polarization (IP) responses are examined for two-dimensional structures using a modeling technique with finite difference method. Percent frequency effect is used for IP parameter because it can be efficiently computed by a perturbation method. Thin conductive, polarizable overburden causes obvious negative IP responses on IP pseudosection. This fact means that IP responses from resistive, polarizable body below the overburden can be masked solely as a function of the resistivity distribution. Resistive, non-polarizable body below the overburden, however, can be detected by the negative IP responses.
