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 <25-60% by volume, vary from 5–20 ?m in size. D-type FIs (type III) account for approximately 20% of the of the observed FIs; and have ellipsoidal or negative crystal forms that randomly distributed within the stages I, II, and III sulfides-bearing quartz veinlets coexist with very low-density vapor inclusions, indicating immiscibility features. At stage III of HF deposit, no halite-bearing inclusions were observed, suggesting that the fluids are relatively NaCl-poor. D-type FIs (type III) are further divided into the DH-, DS- and DC-subtypes in terms of presence or absence of the halite and liquid volume. The DH- subtypes consists of a vaporH2O bubble occupies above 20 and 60%. vol % of the inclusion, a liquid phase and one or more transparent daughter mineral as most commonly halite accompanied by sylvite, without CO2 and opaque minerals. The DM-subtype inclusions, a liquidH2O and a vaporH2O phases, which occupies less than ?30 vol%, one or more opaque daughter minerals as chalcopyrite, hematite, and/or sylvite which occupy more than 50% of inclusion volumes, without vapor CO2 and halite daughter mineral. The DC-subtype contain liquid and vaporCO2 phase which occupies above ?60 vol % of the inclusion, accompanied by different daughter minerals such as halite, sylvite, and small (?1 ?m) unidentified opaque phases. The opaque daughter mineral did not disappear during heating. This subtype inclusion homogenized by halite dissolution after bubble disappearance, and is rarely detected in quartz veins at HF. The treatment of the DM- and DC-subtype with opaque daughter minerals, which did not disappear upon heating, was similar as the treatment of the V, L- and C types during microthermometric measurement. Type IV; C?type (CO2?bearing inclusions); The carbonic (C-type) FIs were identified by "double-eyelid" texture at room temperature, with vapor CO2 phase occupying for 40–80% of total volume. They are ellipsoid and negative crystal shape with 5–25 ?m in size, accounting nearly >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).
