Determination of mineralization zones using interpretation of SIP and Resistivity Data in Tappeh Sorkh Area, Iran-kuh

Accessibility to industrial minerals and ores is one of the necessities to faciliate the development. Meanwhile, it is clear that the shallow mineral resources are near to exhaust, therefore, using modern exploration methods to attain deeper mineral deposits is inevitable. An attampt has been made in this paper to apply and accomplish the results of geological and surface geochemical studies for determination of spatial mineralized zones in western area of Tappeh Sorkh lead - zinc mine (which is one of Bama mining complex mines).IP and Resistivity techniques are the most popular geophysical methods for exploration of Pb and Zn sulfide deposits. There are some advantages in applying SIP method, such as identification of mineralization texture, grain structure, type of material, ore phase and parasitical data. In this study, a relatively new method of time domain SIP was used and apparent time constant, apparent frequency -dependent and true chargeability parameters were extracted. By using the results of time constant parameter, the average of metal grain size was determined, also the amount of metal grain dispersion (mineralization texture) was determined by applying the results of frequancy dependent parameter. Probable mineralization places were determined by using SIP sections. Since the results of raw data do not indicate accurate information about the depth and geometry of mineralization, smooth and parametric inverse modeling were applied to determine probable zones and vertical and horizontal extent of mineralization.
