مطالعه سیالات درگیر در رخداد سلستیت لیکک – استان کهگیلویه و بویراحمد

Celestite mineralization is known from ۳۴ km Northwest of Behbahan city and ۳ km southeast of Likak city , close to the village of Ghabr-e – Gheysar in Kohgiloye – va – Boyer Ahmad Province . Fluid inclusions in the deposit can be classified into five groups : liquid monophase types (L) , liquid – rich types (L+V) , vapor – rich types (V+L) , liquid + Daughter mineral types (L+S) , and liquid + vapor + Daughter mineral types ( L+V+S) . Study of fluid inclusions shows that liquid monophase inclusions are the most abundant type , and hence deposition of celestite has taken place at low temperatures . The last ice melting points of inclusions vary between -۶^۰c and -۲۰^۰c corresponding to salinities from ۹.۲۲ to ۲۲.۶۶ wt% NaCl equivalents . The total density of liquid phase of fluid inclusions is calculated to be ۱.۱۲۵ gr/cm^۳ .
