Abstract

Parkam porphyry copper deposit is situated at 87 Km northwest of Sarcheshmeh porphyry copper deposit and 2 Km of Miduk porphyry copper deposit. This deposit is hosted by Razak volcanic rocks with Eocene age. Copper Mineralization at Parkam deposit is associated with emplacement of diorite and quartz diorite intrusive with Miocene age. Sulfur isotope of sulfide minerals (pyrite and chalcopyrite) suggests a magmatic value about of +0.7 for Parkam deposit. The content of δ34S anhydrite is more than sulfide minerals at Parkam deposit and display the ranges of +11.7 to +21.3 per mil with average of +16.1‰. The sulfur isotopic temperature calculation of anhydrite-pyrite pair is varying from 263.2 to 441.9 °C. The isotopic data show a mixed magmatic-meteoric origin for hydrothermal fluid at Parkam porphyry copper deposit (δ18OH2O=3.08 to 5.67 per mil). The similarity of δ34S content of sulfide and sulfate minerals at Parkam porphyry copper deposit with other porphyry copper deposits at Uromieh-Dokhtar magmatic belt indicate similar process in formation of these deposits.
