Abstarct: Baghkhoshk copper deposit is located in 35km northeast of Sirjan at Kerman province. This area is a part of the central Iran, in particular is situated in the southern part of the Orumieh-Dokhtar magmatic belt. The upper Eocene volcanic rocks is the most widespread lithological units in the area that including andesite - basaltic lava flows, andesite to andesitic-basaltic green tuffs. Diorite and granodiorite massives and quartz-feldspatic dykes introded into the Eocene rock units in Oligomiocene. Copper mineralization in Baghkhoshk area is mainly observed as disseminated, vein- veinlets and breccia. The alterations include potassic, prophylitic, phyllic, argillic, sericite, chloritic and silicic. The ore-forming minerals include sulfides (chalcopyrite, pyrite, bornite, molybdenite, chalcocite and covellite), carbonates (malachite), iron oxides (magnetite, hematite, goethite and limonite) and gangue minerals (calcite, quartz and clay minerals). The main textures of mineralization are disseminated and replacement, also structures include stockwork, vein-veinlets and brecciation. Geochemical studies show that igneous rocks originate from the medium-high potassium calc-alkaline and mextaalumin-low potassium peralumin magma, and related to continental magmatic arcs. The multielements spider diagrams display that negative anomaly of Nb and Ti, which is main characteristics of continental arc- related cal-calkaline magma. The Cu is important element of Baghkhoshk, which has a positive correlation with molybdenum. The Zn, as a pathfinder element of porphyry deposits, have a negative and possitive correlations with Cu and Fe, respectively. baxsed on fluids inclusion study, the homogenization temperature vary from 180°C to 596°C (average 306.41°C) and the salinity range from 0.35% to 42.61% (average of 9.99%), that refers to fluid cooling and mixing magmatic and meteorice waters. baxsed on homogenization temperature and salinity, copper mineralization occurred at a pressure 10-700 bars (average150 bars) and a depth of 200 to 2050 meters (average 1200m). According to the geological, mineralogical, alteration, geochemical, and fluids inclusion features, the Baghkhoshk mineralization introduce a porphyry copper deposit.
