N2 - © 2015.Time-domain induced polarization (IP) data are used for approach to ore prospecting problems on the flanks of the Julietta gold-silver deposit. IP time-domain data are analyzed on the basis of the Debye decomposition, which allows reconstruction of the relaxation time distribution. Experimental dependences of the IP parameters on the main petrophysical properties of disseminated ores were used to interpret field data. The Debye decomposition helped to identify zones of hydrothermally and metasomatically altered rocks containing finely disseminated sulfide minerals, which were missed when using the standard procedure for the analysis of IP data. The estimated content of sulfide minerals in the altered rocks agrees with geological data.
