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...
the ali-abad porphyry copper deposit is located in the central iranian magmatic belt. as a result of subduction magmatism, oligo-miocene leucogranitoid rocks have intruded into conglomerates of lower cretaceous age. due to contact metamorphism the following mineral assemblage has occurred in the altered conglomerate: garnet (andradite-grossular) + epidote+ quartz + calcite + pyrite skarnificati...
Yeylagh-e-Gharechi porphyry copper deposit is located in the Arasbaran metallogenic belt at northwestern Iran, 25 kilometer of Ahar. Porphyry mineralization at the Yeylagh-e-Gharechi deposit occurred in post-Oligocene quartz monzonite and monzonite bodies which was hosted by Eocene volcanic rocks. Mineralization occurred as veins, veinlets and dissemination in hypogene zone. Supergene zone has ...
کانسار مسگرماب در50 کیلومتری شمالشرق شهرستان قائن، در قالب برگه زمین شناسی 1:100.000 آبیز و زون شرقایران واقع شده است. سنگهای آتشفشانیکانسار مسگرماب به سن پالئوسن بالایی- ائوسن، شامل تناوبی ازگدازهها (آندزیت، تراکیآندریت، آندزیت-بازالت و بازالت) و موادآذرآواری (انواع توف وآگلومرا) هستند. این سنگها، بر اساس دادههای ژئوشیمیایی عناصر اصلی وکمیاب، شباهت زیادی بهگدازههای کالکآلکال...
The Sungun copper deposit is located in about 40km north west of Ahar city in the east Azarbaigan province of Iran. The total geological ore deposit is estimated to be 740 million tons. In this study using all information from exploration and geotechnical studies of the area, final pit limits of Sungun copper deposit is designed by the 2-D Lerchs & Grossmann Algorithm. By this method, from 740 ...
We have developed an electroformed copper lining having highly clean and smooth surface (i.e. little outgassing and high conductive copper) for use in accelerator components. The copper lining is produced by periodic current reversal electroforming with a low copper-content acid copper sulfate bath containing the specified amount of chloride ions (PR process). Deposit by PR process has the same...
metres north of Stewart, British Columbia. Reserves calculated in 1989 by the previous owner, Western Canadian Mining Corporation. are 66 million tonnes averaging 0.8 per cent copper and 0.33 gram per tonne gold using a 0.5 per cent copper cut off, Access to the deposit is by helicopter from Tide Lake airstrip 50 kilometres north of Stewart. The deposit was diamond drilled extensively by West...
The Lapeh-Zanak copper deposit is located about 15 km east of Tehran, in the southern part of the Central Alborz Zone. The rock units exposed in this area include a sequence of volcanic and pyroclastic rocks (basalt, andesite, trachy-andesite and dacitic and vitric tuff) belonging to the Fajan Formation with the Paleocene-Lower Eocene age, which are cut by subvolcanic igneous masses with a comp...
The Bozjani copper deposit is located about 30 km west of Fariman city, Khorasan Razavi Province. Host rocks to mineralization are mostly pridotites and basalts of Fariman ophiolitic sequence. Ore body consists of two parts: lower and upper. Lower part has formed a stringer of primary sulfides as stockwork, veinlets, and disseminated. Uppermost part has lenticular shaped dominated by ribbon-lik...
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...
