Bozhan area is located in southernmost parts of the eastern Alborz mountain range in NE Iran and is part of the Binaloud structural zone. Geology of the study area include andesitic, trachyte, basaltic and basalt-andesite lavas, which are accompanied by intrusive, subvolcanic, and pyroclastic rocks. These rocks have undergone propylitic alteration. Mineralization occurs mainly along silicic and carbonate veinlets and has a variety of open space-filling, coliforms, brecciate, and vein-veinlets texture. Chalcopyrite is the most important and abundant sulfide mineral in these veins. Microthermometeric investagations were conducted on and in liquid-rich (L+V) fluids. Homogenization experiments revealed a temperature range of 195 to 262 ° C for the studied inclusion and salinity ranges from 10.61 to 14.67% NaCl equivalent. Reduction temperature and cooling are the most important factors in the deposition of metals along with the ore-fluid in the Bozhan exploration area. Meanwhile, mineralization in the Bozhan exploration area has a vein-veinlets trend that is consistent with existing fractures. Based on field observation, mineralogy, structure, texture and fluid inclusion, the Bozhan exploration area can be considered as epithermal vein systems.
