Abstract
CURRENT AND FRE.QUENCY EFFECTS IN THE INDUCED
POLARIZATION (IP) METHOD
A laboratory equipment, having the frequency range 10 -2 to lO +G Hz and measuring directly the real and imaginary resistivity components of the rock samples, iwas developed for the investigation by multifrequency IP (or complex re& istlvity) method. Various rock samples corresponding natural conditions, and artificial samples like metallic and non - metallic plates being more stable physical conditions, rvvhich could represent various IP phenomena, have been prepared. In the studies on experimental, the electrolytes of different concentration such as I\804 , NaCl and CuS04 1were used. After measuring real and imaginary components of response potential in the frequency range mentioned, resistivity and phase spectra are obtained separetly by using various current densities. Thus, non - linear properties of IP phenomena are also determined at the same times. The results show that; (1) The critical frequency which define the mruximum of the phase spectrum is changeable according to electrolyte concentration of the medium, (2) The critical frequency does not depend on the current density, (3) If a medium contains only non - metallic minerals, IP spectra for various current densities linearly decreases, ( 4) If a medium containing only metallic minerals, IP spectra show non - linear behavious 1with varying current densities. The results obtained in this study give us a neiw opportunity to enter into the details of the electrical properties of rocks. Therefore, this investigation can be very usefull especially discriminating metallic and non - metallic mineral zones of a sulfide mines and for other special problems.
