Abstract

Rock unites which are exposed in Tak-I mine area are: Taknar formation (Ordovician), Mid-late Paleozoic and younger intrusive rocks. Taknar formation consists of sericite schist, chlorite schist, chlorite-sericite schist and some meta-diabase- gabbro-diorite. Taknar Polymetal (Cu-Zn-Au- Ag-Pb) MASSIVE SULFIDE deposit formed at certain horizon of Taknar formation. Three style of mineralization are: stockwork, layered and massive. Due to strong tectonic activity in the area, dimension and geometry of deposit are being changed. Para genetic minerals within the massive and layered are: magnetite + pyrite + chalcopyrite ± sphalerite ± galena ± sulphosalt ±gold + chlorite ± carbonate± Seri cite. Magnetite is the main mineral in the massive zone. Par agenesis within stock work are: pyrite + chalcopyrite ±magnetite + chlorite + quartz + sericite ±carbonate. Based on mineral par agenesis, the ore bearing solution had the following condition: T≥ 270°C, pH= 5 -7, Logƒ02 = (-29) to (-30). Also, The range of chemical composition of some elements within Tak-I MASSIVE SULFIDE is as follow :Cu = %0.01 - %5.86, Zn = 269 -15600 (ppm), Pb = 27 - 4400 (ppm), Au = 0.86 - 7.53 (ppm), Ag = 2.4 - 95.1 (ppm), Bi = 34 - 2200 (ppm).Based on the par agenesis, alteration, style of mineralization, petrography, geochemistry, and structure, Tak-I is part of MASSIVE SULFIDE deposit. Due to high content of Cu, Zn, Au, Ag and Pb, Taknar MASSIVE SULFIDE deposit is a polymetal deposit. Based on high magnetite within sulfides and lack of pyrrhotite, Taknar is a special MASSIVE SULFIDE deposit.
