They different daughter minerals such as halite, sylvite,

They are between 5 and 25 ?m rounded isometric, elongated and negative-crystal shapes and mainly homogenized to vapor. No CO2 were observed in V-type inclusions during microthermometry. Vapor-rich inclusions are the most common type in all mineralized quartz veins account for approximately 60% of the total number of inclusions and are distributed in groups or alone in quartz various stages accompanied by sulfide minerals. The L-type and polyphase hypersaline fluid inclusions were associated with vapor-rich inclusions either randomly or in clusters in the A, B veins and a lesser extent in D veins from potassic and sericitic alteration zones quartz except the late stage.

Type III; The Daughter mineral-bearing; D-type FIs (type III) consist of one or more daughter minerals (50 % to 20 % volume of FIs), aqueous solution, and a vapor bubble ranging between 5 % by volume of the total FIs which occasionally observed in the sulfide–bearing quartz of stages I, II, veins of the Haftcheshmeh deposit. They can subdivided into the following C-1 and C-2 subtypes based on observed phases at room temperature:

C-1: contains three phases (liquid H2O+liquid CO2 + Vapor CO2)

C-2: contains four or more phases (VCO2+LCO2+LH2O+halite+Opaque).
