Abstract

The spectral parameters of the Cole-Cole model can be used to distinguish the IP anomalies of different geological bodies. However, the frequency domain IP requires a lot of observation data and its efficiency in field work is low. In view of this reality which is very common to use the data of the time-domain IP. It is necessary to study the law of the time-domain solution of Cole-Cole model with induced polarization method. First of all, this paper transforms the complex resistivity in the frequency domain into the time-varying resistivity in the time domain through the inverse Laplace transform, then by changing different Cole-Cole parameters in the time domain so that we can observe the changing law of time-varying resistivity time-spectrum characteristics caused by different parameters.
