The aim of this study is gold and its element mineralization in Gholgholeh area. The Gholgholeh area is located in 40 Km southwest of Saghez city and in northwest of Kordestan province. The case of study in the oldest rock-unit outcrops in the north of this area which belongs to Percambrian gneiss. Permian deposit mostly distributed in north, northeast and northwest of this area. The major types of alteration are composed of silicification, sulfidation, sericitization, chloritization and carbonatization. sercitization and choritization are the most. SEM and mineralography studies indicate occurrence of sulfide mieralization especially Au sulfides which appears in two generations. On the basis of SEM studies, little Ag and As are observed. There is no gold in calcite. Primary mineral consist of: pyrite, marcazite and calchopyrite, and secondary minerals are pyrite, coveline and realgar. On the other hand, fluid inclusion studies shows 350ºC temperature in gold formation. Evidence like Parageneses, elements, gangue and alteration around mineralization area all indicate the presence of monometal gold vein ore deposit of quartz vein type replaced by gold vein in cracks which are depended on this structure.
