Sedimentary Copper mineralization has been observed in Monj and Jolany locations in Bavanat (Sanandaj – Sirjan metamorphic belt). According to current study, the host rocks for copper mineralization in this area are green sandstones, generally in subarkose and arkose groups. Age of these sandstones is middle Jurassic. Copper mineralization is observed in two forms, sulfides form including chalc...
cheshmeh-konan area is located ~15 km northwest of tasuj, east-azarbaidjan province. the most important lithologic units of the area are red sandstones, green-gray sandstones, shale, and marl (miocene). based on field evidence and petrographical investigations, the host sediments were deposited in a peritidal setting associated with a sabkha-type environment. copper mineralization in the area o...
The sedimentary copper mineralization of the Sorkheh area is located about 20 km northwest of Marand, East-Azarbaidjan Province, northwest Iran. The most important lithologic units in this area include sandstones and red-color shales, with the Late Miocene age, that are intruded by lamprophyric dike. The copper mineralization in the study area occurred as stratiform laminations and disseminatio...
kalchoye copper-gold deposit is located about 110 kilometers east of esfahan province and within the eocene volcano sedimentary rocks. sandy tuff and andesite lava are important members of this complex.the form of mineralization in area is vein and veinlet and quartz as the main gangue phase. the main ore minerals are chalcopyrite, chalcocite, galena and weathered minerals such as goethite, iro...
Band-e-Ghichy copper deposit is located in the northern margin of the Central Iran structural zone, about 120 km south of Shahrood and 70 km south east of Torud. Copper mineralization occurred in the rock units including sandstone, conglomerate and siltstone with the Oligocene age. Mineralization has occurred in the form of stratiform (syngenetic), stratabound (epigenetic) and supergen (the sur...
Loco-granite and granodiorite intrusive bodies have cut the Naiband and Sangestan Formations in Darreh-Zerreshk area in southwest margins of Shirkooh batholite. This intrusion has caused weak metamorphism and copper hydrothermal mineralization in permeable Sangestan Formation. The characteristics minerals are magnetite, chalcopyrite, pyrite, bournite and dyajenite. The studied area is composed ...
Zaveh copper mineralization is located SE of Torbat-e-Hydarieh in Khorasan Razavi Province, in Khaf-Kashmar-Bardaskan Metallogenic Zone. Geology of the area includes Jurassic and Cretaceous sedimentary rocks and Eocene andesitic to rhyodacitic volcanic rocks. Mineralization is structurally controled and occurred as vein-veilet form with east-west ternding and hosted by Jurassic silicate-cemente...
: KC5 copper exploration prospect is located 80 Km to the northwest of Bardaskan and 4 Km to the Northeast of Dahaneh Siah copper mine in Khorasan Razavi. KC5 and Dahaneh Siah areas belong to Sabzevar geological Zone. Copper mineralization is observable mainly as secondary minerals such as Malachite and Chlorite which fills joints and fractures in a faulty contact at the boundary of the volcani...
Bovaki and Aghbolagh tungsten (copper-tin-zinc) ore occurrences are located 12 and 14 km northwest of Azna respectively. The region is located in Sanandaj-Sirjan structural zone of Iran, at the complex deformation sub-zone. There are alternative comsisty Upper Triassic carbonate, quartzite and meta-volcanic rocks (such as meta-tuff). In this area, tungsten-copper mineralization occurs as strati...
the sorkheh deposit in northwestern iran exhibits several readily visible general characteristics of sediment-hosted stratiform copper (ssc) mineralization. it consists of fine-grained disseminated base-metal sulfides within gray sandstones (gray beds, the basal whitish miocene sandstone and shallow-water) that overlie a thick sequence of red beds (miocene upper red formation). the host gray be...
