The fluid inclusion studies indicate three different types of aqueous fluid inclusions at the Emarat deposit, namely highsalinity brine (type II), low salinity meteoric water (type III), and a fluid of intermediate salinity (type I). The high salinity (type II) brine exhibits an average salinity of 15 wt.% NaCl equiv. Low-salinity (type III) inclusions are characterized by an average salinity of 1.7 wt.% NaCl equiv. Inclusions of intermediate composition (type I inclusions) possess an average salinity of 7.8 wt.% NaCl equiv. This fluid of intermediate salinity is best explained as a mixture of high-salinity type II and low-salinity type III fluids.Homogenization temperatures for fluid inclusions occupy a wide temperature range between 90oC and 257oC, with 80% of all inclusions falling in the range of 150oC and 257oC. No significant differences in homogenization temperatures exist between the different types of aqueous liquid-vapor inclusions.Fluid inclusion data provide very strong evidence for fluid mixing at the Emarat deposit. This and the large range of homogenization temperatures may be used to suggest that fluid mixing and cooling were two important mechanisms contributing to mineral deposition at Emarat.
