Abstract: 

Middle Permian carbonates of Roteh Formation in Alborz Mountain of NOTHERN IRAN host a number of stratabound barite and galena deposit. Microthermometric measurements on two phase (H2O + vapor); water rich inclusions with low vapor to liquid ratios yield a mean homogenization tempretures of 105oC. Salinities range from 20.4 to 23.9 equiv.wt percent NaCl. The constant salinity during barite and galena deposition and lack of correlation between salinity and mineralization tempreture indicate that mixing of fluids with different salinities did not occur in the ore zone.
