Abstarct: The Koh-panj copper deposit is located in Kerman province and 65 km of Sirjan city. This area is situated in the southern part of the Orumieh-Dokhtar magmatic belt and the Dehaj-Sarduieh magmatic belt. Dacite and granodiorite bodies intruded into Eocene volcanic-sedimentary sequence including lava and rhyodacite tuffs. The granodiorite, diorite and dacite dikes derived from this intrusive. The hydrothermal alterations in the area include potassic, phyllic, argillic, prophylitic, which are accompanied by sericite and silicic alterations. The mineralization divided into hypogene and supergene zones. The hypogene ores, in order of frequency, include pyrite, chalcopyrite, magnetite, oligiste, galena, sphalerite, bornite, and rarely molybdenite. The supergene minerals include hematite, goethite, limonite, malachite, azurite, Chrysocolla, and low calcite and covellite. The structures of Mineralization are stockwork, vein-veinlets and the main textures are disseminated, vein-veinlets and displacement. Geochemical studies show that igneous rocks originate from the medium-high potassium calc-alkaline and mextaalumine- peralumine magma, and related to continental magmatic arcs. baxsed on the results of spider diagrams and other geochemical properties, rock forming magma have the characteristics of high-silica adakitic magmas. The average grade of Cu and Mo are 0.21% and 43 ppm, respectively. The correlation between Cu and Mo is positive, but their correlation with pb, Zn and Fe is negative. baxsed on fluid inclusion study, the homogenization temperature vary from 214.9°C to 569.95°C (average 356°C) and the salinity range from 0.35% to 69.38% (average of 27.15 wt% NaCl equev.), that refers to fluid cooling and mixing magmatic and meteoric waters. baxsed on homogenization temperature and salinity, copper mineralization occurred at a pressure below 700 bars and a depth of 400 to 1420 meters. Finally, according to this studies the Kouh-panj mineralization suggest a porphyry type copper deposit.
