Carbonate mineralization is present in many hydrothermal deposits including base-metal veins and mesothermal gold deposits. In the Chehelkureh deposit, carbonate minerals occur in all host, altered and mineralized rocks. The ubiquitous occurrence of these minerals makes them potential indicators of changes in physical and chemical parameters during the evolution of the hydrothermal system. In this study we use chemical compositions of carbonates to 

The fault-fill mineralization includes quartz, dolomite, ankerite, siderite, calcite, molybdenite, pyrrhotite, arsenopyrite, pyrite, chalcopyrite, sphalerite, galena, selenian galena, marcasite, ilmenite, and rutile (Maanijou 2007).
