Abstract: 
Iju porphyry copper deposit is located in southern part of Orumieh-Dokhtar volcano-plutonic belt, northwest of Shahr-e-Babak. The area is composed of an Eocene volcano-pyroclastic complex intruded by Oligo-Miocene diorite-quartzdiorite porphyries. The intrusive bodies contained several alteration mineralization producing phases. Minor potassic (biotite), phyllic, clay, propylitic and silicic alterations are observed in the area. Mineralization occurs as hypogene, secondary sulfide enrichment and oxide. Lithogeochemical data show that the main part of the Iju deposit was destroyed due to surficial processes. Average salinity for the two-phase liquid-rich fluid inclusions studied in quartz grains is 24.6 wt% NaCl equivalents. Average homogenization temperature for the fluids was 296.8°C and the emplacement depth is calculated as being about 500 meters. Combination of mono-phase gas and multi-phase fluid inclusions indicating boiling as well as low average of Cu content imply that the initial ore-forming fluid was poor in Cu and it would be unlikely to find copper at deeper parts of the deposit.
