Coexisting Tetrahedrite–(Zn) and Sphalerite at the Teremki Gold-Ore Deposit (East Transbaikalia): Chemical Composition and Formation Conditions
نویسندگان
چکیده
Abstract Paragenetic associations of tetrahedrite-(Zn) and sphalerite are distinguished in the Teremki gold-ore deposit. The chemical composition coexisting minerals this association is determined. Sb/(Sb + As) Fe/(Fe Zn) ratios vary from 0.66 to 0.97 0.28 0.40, respectively. A negative correlation was established between ratios. Contents Fe change 0.88 1.43 wt % (1.5–2.5 mol FeS). Temperature sulfur fugacity when precipitation tetrahedrite-(Zn)–paragenesis were estimated: they range 130 280°C 10 –13.2 –8.1 bars,

Ore mineralogy and fluid inclusions constraints on genesis of the Muteh gold deposit (western Iran)
The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...

متن کاملThe Application of Artificial Neural Networks to Ore Reserve Estimation at Choghart Iron Ore Deposit
Geo-statistical methods for reserve estimation are difficult to use when stationary conditions are not satisfied. Artificial Neural Networks (ANNs) provide an alternative to geo-statistical techniques while considerably reducing the processing time required for development and application. In this paper the ANNs was applied to the Choghart iron ore deposit in Yazd province of Iran. Initially, a...

15 صفحه اولOre Deposit Types and Their Primary Expressions
Metals are largely derived from the mantle or crust by partial melting and fluid-related leaching. Ligands can be provided from the same sources, or from the atmosphere, hydrosphere and biosphere. Transport is mainly by mechanical or mass transfer mechanisms and by fluids. On and near the surface, biological processes can also concentrate and transport ore components or remove non-ore component...
