Interpretation of geophysical (IP/RS) and geological data of Gonharan lead and zinc exploration area (east of Daran city- Isfahan province

The Pb and Zn range of Gonharan is in the carbonate part of Sanandaj-Sirjan zone, with early Cretaceous massif limestone host rock. Mineralization is mainly associated with dolomitic-siliceous alteration. The mineralized dolomitized sections are mostly related to reverse fault zones and have a trend approximately parallel to reverse faults and fracture surfaces. The mineralization of the mineral material is in the form of scattered grains, veins, empty space filling and patches. Minerals include lead, zinc, and sometimes copper, which are in the form of galena, sphalerite, pyrite, chalcopyrite, cerusite, calcite, and silica. Collecting the data of inductance and specific resistance has been designed and carried out first in the form of a rectangular arrangement in order to determine the abnormal ranges and then using a dipole-dipole arrangement in order to explore the lateral and deep points of these anomalies. Also, the data modeling of induction and specific resistance was done by two-dimensional smooth inversion method, and to better display the results, all two-dimensional sections were combined and a three-dimensional model was presented. The studied area is divided into two parts, and the total points collected in the two areas by induction polarization method and apparent specific resistance are 3313 stations, and finally, 45 points are suggested for drilling in the two areas.
