Abstract

Introduction: The Barik-Ab mine is located in the northeast of ABHAR city (Zanjan province). It is occurred in Alborz-Azarbayjan zone. Breccia tuff and rhyolitic to dacitic lavas are the major rock unites in this area which belongs to Karaj Formation.Aim: Investigating ore mineralization process and it relates to the coexist intrusive rock. Determining the alteration zones and ore deposit genesis.Materials and Methods: After field studies, petrology and ore mineralization were distinguished by the study of 35 thin and polish sections. Different analyses were done for petrography studies and ore grade determining.Results: Mineralization occurred mainly as open space filling and dispersed through the country rock. Mineralization of Pb and Zn, are in the form of galena and sphalerite with paragenesis of chalcopyrite, pyrite, bornite and etc. On the basis of analytical studies, the mean grade of Pb in the samples is 8.02%, Zn=3.4%, Cu=2.09%, Au=918 ppb and Ag=93-197 ppm. In the mineralography studies tetrahedrite is observed within galena.Conclusion: During the extensional phases of Oligocene, the intrusive and volcanic masses in this area were possibly thermal source for transporting of the hydrothermal fluids. Mineralization of this mine is similar to the descriptive model of polymetallic vein deposits.
