The Alshar epithermal Au-As-Sb-Tl deposit, southern Macedonia

Magma and mineralization controles of Zavarian (Salafchegan) epithermal Au (Cu) in comparison with Sari-Gunay epitermal Au (Qorveh) deposit

Zavarian epitermal gold (copper) deposit is located in an intracontinental volcanic cone (stratovolcano) with the Early Miocene age, in the middle of the Urmia-Dokhtar magmatic arc. The host rocks of this mineralization include a set of basaltic, andesitic-basaltic, andesitic, dacitic, as well as granodiorite and tonal units that have been exposed in volcanic form (lava and pyroclastic) and sem...

MODELLING THE As-Au ASSOCIATION IN HYDROTHERMAL GOLD MINERALIZATION: EXAMPLE OF ZARSHURAN DEPOSIT, NW IRAN

Iron 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 ...

The study area is located south of Nehbandan, in southern Khorasan Province. There are three mineralization zones with three veins in this area which number two is antimony rich and has anomaly for Au and Hg. This zone is composed of silica-carbonate with stibnite, pyrite, chalcopyrite and Fe-hydroxide. The textures of veins are open space filling, brecciate and colloidal. Mineralization occurr...
