Techniques for estimation of the intrinsic Cole Cole parameters of a buried polarizable body are studied.it is shown that the nomograph correction technique can be used only if the resistivity distribution of the earth model is known and the resistivity of the polarizable body is approximate to that of the country rock,and that it is impossible to estimate the intrinsic Cole Cole parameters by using the techniques based on inversion of the spectrum measured at one station,provided the resistivity distribution of the earth model is not known.It is alsoshown that for some simple earth model,the technique based on joint inversion of the spectra measured at two or more stations can be used to estimate the intrinsic Cole Cole parameters.It is suggested that a techinique which determine the resistivity distribution of the earth model first and then estimate the intrinsic Cole-Cole parameters by inversion of the spectrum at one station may be a suitable techinique.
