The spectrum parameters of Cole-Cole model can be used to distinguish the polarization bodies and explore deep ore deposits based on induced polarization anomalies.Due to the low efficiency in field work, this technique has not been widely used in exploration. Current time-domain IP instrument can observe the apparent chargeability data which can reflect the attenuation of secondary polarization potential in multiple time intervals. According to the theory that SIP and TDIP can be transformed mutually, in this paper the authors presented a method for extracting the Cole-Cole model parameters from TDIP data, which achieved good prospecting results while applying to the field geological exploration work.
