Barite Mineralization In Volcanic Rocks In Southern Flank Of East-Magnitogorsk Palaeoisland Arc (South Urals)

The problems of ore-bearing palaevolcanic structures in folded belts are actual because of their high productivity in nonferrous, ferrous and noble metals ores. Now relationships of location and conditions of formation for sulfide-massive and gold-bearing deposits are investigated very well in Urals. But carboniferous sulfide-barite mineralization, for example the barite veins in Arcaimsky palaevolcano are?nt studied enough now [3-5]. The purpose of this research is the studying of mineralogy and thermobarogeochemistry of barite from the hydrothermal veins. It will allow to determine the conditions of its formation and to compare it to the similar mineralization of others ore types.
