Zuzan region is located 80 km southeast of Torbat Heydariyeh city (northeast of Iran). This area is located in the northern part of the Lut block and the oldest rocks in the area include Staurolite schist’s, Garant Muscovite Shist and Transformed Limestones belonging to the Paleozoic, the main rocks of the region, deep and semi-deep penetrating masses in Diorite, Andesite, Andesite Porphyritic, Monzonite, granodiorite, belongs to the Paleocene. In the penetrating masses of the area, large and different alteration zones can be seen. Ultrasonic zoning in the area includes porphyry alteration, argillic, quartz seresite, pyrite and getting Skarn and a combination of these. Based on the combination of mineral cognition and high magnetic acceptability (on average about SI 5-10 × 500), the permeable masses of the region belong to the magnetite series (oxidant type) and are of type I granites. The presence of extensive and suitable alteration systems, the presence of semi-deep masses such as Monzonite masses, Monzonite quartz, Diorite and Diorite quartz, the general tectonic and geological pattern and the Magma series west of Zouzan confirm the exploratory potential for the porphyry system in the area, also study used fractal-grade methods - number in the range for the elements gold, copper, silver, lead and zinc to identify and identify multiple statistical communities for each of these elements in the Zouzan range. The aim of this study was to investigate the genesis and origin of mineralization and fluid studies involved in Zouzen region, to do this, three samples of calcite particles were found in volcanics in the area. After preparing two-polished sections in the Mining Laboratory of Iran's Mineral Processing Research Center, Were studied. Based on the results of these studies, it can be stated that the fluids are formed in low pressure environments (50-100 bar and low salinity (0-5% wt.) and have a low density of (0.7 to 1 gr / Cm3), also to determine the origin of fluid intermediates, the diagram of the homogenization temperature against salinity was used, These studies have determined the origin of these intermediates as fluids with a source of metamorphosis and atmosphericity. It is possible to pay attention to the conditions of the deposit as well as the low salinity rate and the average homogeneity temperature of these mediums. According to all the above information about the Zouzan deposit, considered the deposit to be part of the margins of a porphyry mass, Due to the infiltration of apophyses from the main mass, it has caused mineralization and also the phenomenon of Skarn in the vicinity of limestone in the study area.
