Investigation of chemistry and the style of formation of calc-silicate minerals in Aghbolagh skarn zone, north of Oshnavieh, West-Azarbaidjan Province, NW Iran
The Aghbolagh area is located about 21 km north of Oshnavieh city, West-Azarbaidjan Province, NW Iran. This study showed that the Fe-Cu skarn deposit in this area can be separated into two zones, (1) Garnet skarn and (2) Garnet-pyroxene skarn. Based upon the results of electron probe micro-analysis, the garnets are chemically of andradite-grossularite type with dominant andraditic component. Th...
متن کاملThermobarometry and chemistry of garnet and pyroxene minerals of Oshvand skarn deposit, Nahavand, West Iran
The Oshvand Skarn deposit is located about 10 km east of Nahavand city in the Sanandaj-Sirjan structural zone. In this area, garnet (grossular-andradite) is the most abundant mineral in the skarn zone and their compositions are in the range of Adr(67.2 - 45.9%) Gro(50.1 - 31.8%) Sps(1.8 - 0.3%) and Prp(2.5 - 0.6%). EPMA data indicate a decrease in andradite and increase in the amounts of grossu...
متن کاملPressure, temperature and fluid composition in the Kalaybar aureole, NW Iran; Mineral equilibria in metapelitic and calc-silicate rocks
Intrusion of the Kalaybar nepheline syenite into the Cretaceous pelitic and calcareous sediments has produced a thermal aureole up to 1km thick. Six mineralogical zones are developed in the pelitic rocks with minerals such as cordierite, K feldspar, sillimanite and corundum. Chemically suitable rocks are partially melted in response to the heat from the pluton. Five mineralogical zones are deve...
متن کاملMineral chemistry of magnetite and fluid inclusions studies in the Kuh-Baba iron deposit, south of Hashtroud, NW Iran
The Kuh-Baba iron ore deposit is located about 70 km south of Hashtroud, East-Azarbaidjan Province, NW Iran. The deposit is genetically affiliated with intrusive bodies of gabbroic to dioritic composition. The principal host rocks for the Fe mineralization include units of gabbro-norite and pyroxene hornblende gabbro-norite. The widespread alteration zones which are accompanied with Fe-minerali...
متن کاملApplication of mineral chemistry to mineralization and alteration evaluation in Zn-Pb Angouran deposit, Zanjan
Angouran zinc and lead deposit is located about 135 km west of Zanjan city, in the northwest of the Sanandaj-Sirjan structural zone The results of this study indicate that the dolomitic alteration occurred in the carbonate hanging-wall and the presence of ankerite in the schist footwall. The main host of ore deposit is metamorphic carbonate. The Angouran dolomite is secondary and hydrothermal. ...
