Abstarct: Satveh copper exploration area, 130 km south of Damghan city in Semnan province, is part of a Torud-Chah shirin volcanic-sedimentary belt that has facies in the northern edge Structural-sedimentary zones of Central Iran. Investigations on host rocks in the desired area Existence of small outcrops of pyroclastic rocks (lithic crystal tuff) to Eocene age with semi-deep intrusions (quartz monzodiorite, granodiorite and granite) it is of Eocene-Oligocene age. These rocks are associated with a variety of argilitic, sericitic, silicic, carbonatic, chloritic, and iron oxides alterations around the veins and in parts of the area. In addition, they are high-K, calc-alkaline in nature. Mineralization in Satveh exploration area occurred as veins along the fault planes in a semi deep intrusions Fractures resulting from operation of faults in the rocks of the region have created a favorable location for the influence of hydrothermal solution and it is considered as the main controller of mineralization.¬ According to the field observations and mineralogical studies, the mineralization in the region was carried out in two stages: hypogene and supergene and weathering. Hypogen zone minerals are generally pyrite and chalcopyrite. Because of existence in oxidizing-supergene environment, nearly almost Cu bearing minerals of the main stage of mineralization have been replaced by secondary Cu minerals such as chalcocite, digenite, malachite and azurite. The most textures observed in the occurrence of mineralization include vein-veinlets, open space filling, colloform, replacement and disseminated. According to the geochemical data, the area rocks have significant enrichment in LREE and LILE and depletion in HREE and HFSE and negative anomalies in Ti and Nb elements. Fluid inclusion data shows in the temperature range from 130 to 190 °C and salinity between 2.02 and 6.71Wt %NaCl. Most of the studied fluid inclusions are from liquid rich two phases (L+V) type. On the baxse of a forementioned evidences, the principle deposition mechanism of ore minerals was mixing of two meteoric and magmatic fluids. finally, regarding our research the petrography, struactural control of mineralization, alteration type and its extention, simple mineralogy, geochemical, fluid inclusion properties of the study area and comparison with similar epithelial deposits, Satveh copper exploration area can be classified as vein type copper deposits.
