KUSHK ZINC-LEAD DEPOSIT A TYPICAL BLACK-SHALE-HOSTED DEPOSIT IN YAZD STATE, IRAN
Kushk zinc- lead deposit is located about 167 km east of the city of Yazd, Iran. The geographical location of the mine is 31°, 40' N and 55", 40' E. Different rock types including volcanics and subvolcanics (rhyolites, rhyodacites, dacites, and rhyolitic tuffs) and sedimentary rocks (shale, limestones and dolomites) crop out in the area. Mineralization of the deposit occurs in black shale o...
متن کاملSediment-hosted, Disseminated Gold Deposits Related to Alkalic
This paper describes occurrences of low grade, disseminated gold in sedimentary rocks and alkalic intrusions in the vicinity of the Howell Creek Structure (HCS; Price,1964) of southeastern British Columbia. The study is part of the B.C. Geological Surveys ongoing Sediment-hosted Gold Project, which is examining occurrences throughout the province which may have similarities to gold deposits in...
متن کاملMineralogy and Geochemistry Studies of the Sorkheh Sediment-hosted Stratiform Copper (SSC) Deposit, NW Iran
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...
متن کاملGeology and Alteration at the Mount Milligan Gold-copper Porphyry Deposit, Central British Columbia
The Mount Milligan deposit, centred at latitude SS”O8’ north and longitude 124”04’ west, is 100 kilometres westsouthwest of Mackenzie and 160 kilometres northwest of Prince George in central British Columbia. The deposit occurs in gently rolling topography (Plate 2-6-l) 5 kilometres due south of Mount Milligan. Access to the property is by a 93.kilometre logging road that connects with the Hart...
متن کاملIron sulphides at the epithermal gold-copper deposit of Palai-Islica (Almeria, SE Spain)
Au-Cu mineralization at Palai-Islica occurs as disseminations in massive silicified volcanic rocks and, more abundantly, in sulphide-bearing quartz veins. The major ore minerals in the deposit are pyrite ± chalcopyrite, sphalerite and galena and there is a great variety of accessory minerals, including Au-Ag alloys and native gold. Pyrite, the most abundant sulphide, is closely associated with ...
