Pb-Zn deposits at Irankuh range are located along Irankuh Mountain 25 km south west of Isfahan along Sanandaj-Sirjan structural zone. The host rocks of the deposit are mainly Cretaceous carbonate and Jurassic shale units; however, it is mainly formed inside carbonate unit. Sulphide minerals of the deposit are mainly composed of sphalerite, galena and pyrite. The most abundant mineral is sphalerite that is evenly distributed in a matrix rich of pyrite and galena. Pyrite is one of the commonly found minerals which are formed during most of mineralisation episodes as intergrowth. This research focuses on recognition of pathfinder and paragenetic elements in Gushfil deposit and origin mineral of these elements. Based on the performed analyses (ICP-OES) on shale, dolomite an ore samples (collected in the area) and their comparison with local and global shale analyses the following elements are determined Ag, Sb, Cd, Co, Li, Zn and Pb and the bearing minerals are sphalerite, galena and pyrite.
