The Muteh gold district is located about 70 km northeast of Golpaygan within Sanandaj-Sirjan metamorphic zone of Zagros Structural Belt. Geological studies show that the area had been under poly - phase metamorphism. Gold mineralization occurs in metamorphic complex which consists mainly of green schists, meta-volcanics, and gneisses. Shear zones are the host of gold mineralization, and intense...

Torud-Chah Shirine magmatic arc is located in south of Semnan. This arc is composed of Cenozoic volcanic, pyroclastic and intrusive rocks. The Kuh-Zar in manning province of Bagho is outstanding with Cu-Au mineralization. Mining is restricted to hydrothermal alteration zones in the area. Alteration zones includes propylitic, phyllic, advanced argillic and silicic. The rare association of tourma...

Masjeddaghi area is located about 35 km east of Jolfa, north of East-Azarbaidjan province. Field and mineralogical studies show that quartz-diorite subvolcanic stock and quartz-andesitic volcanic rocks in this area were altered by both hypogene and supergene hydrothermal solutions. Alterations are genetically affiliated with four groups of (1) quartz, (2) sulfide, (3) sulfate, and carbonate vei...

Balazard area is located in west of Nehbandan in the center of Lut Block. Eocene andesite and rhyolite cover most of the area. Subvolcanic rocks such as quartz monzodiorite porphyry, biotite quartz diorite porphyry, pyroxene hornblende diorite porphyry, hornblende pyroxene quartz diorite porphyry and hornblende diorite porphyry intruded the volcanic rocks. Evidence such as disseminated sulfide ...

The Yaralujeh vein index is located about 40 km NW of Ahar, East Azarbaijan. The host rock of mineralized vein is an altered subvolcanic body, intermediate in composition. The mineralization of sphalerite-galen-chlcopyrite recognized as intersected veinlets. Based on field observations, textural and mineralogical evidences, the mineralization occurred in 4 stages. The subvolcanic rocks are affe...
