The Tanurjeh area is located in the Khaf-Darouneh volcano-plutonic belt, North of Darouneh Great fault. Eocene \\\\\\\"Volcanicrocks such as rhyolite, dacite, rhyodacite and minor andesite are present. They are found mainly as tuff, lapilli tuff and flow. 19 sub volcanic (Oligo-Miocene) bodies with composition of monzonite, quartz monzonite, diorite and quartz diorite porphyry are mapped. Different types of alteration such as propylitic, solidification with vugs, sericitic are well developed in the area. Silicified zone cover a large area. Alteration zones are not linear and it is inferred that they are formed due to sub-volcanic intrusive. Pyrite and minor chalcopyrite are the main primary sulfides. They occur both as dissemination and fracture filling. In most of the areas, sulfides are oxidized. Secondary oxides are between 0.3 8 percent. Au, Cu, Zn, Pb, As, and Mo show anomaly in the area The Au content of rock samples are between 0.1 11.2 ppm. Tanurjeh has several features analogous to gold-rich porphyry deposits: cluster of sub-volcanic intermediate calcalkaline rocks, hydrothermal alteration closely associated with the intrusive bodies, present of gold anomaly in most of the area, extensive solidification. (vuggy quartz) is dominate, and presence of pyrite, mostly oxidized, both disseminated and veinlets.
