Thermobarometry 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 کاملCarbon and Oxygen Isotopic Systematics in Calcite and Dolomite from the Sangan Iron Skarn Deposit, Northeastern Iran
A total of 40 samples from carbonates and 8 samples from silicate rocks were analyzed from the Sangan iron skarn deposit to examine behavior of the oxygen and carbon isotopes. The higher values of ?18O are from metamorphic calcite and dolomite and lower ones are from granitic rocks. Although the ?18O and ?13C values of calcite and dolomite in marble yield the highest values in the Sangan deposi...
متن کاملIndium Mineralization in a Sn-Poor Skarn Deposit: A Case Study of the Qibaoshan Deposit, South China
Indium (In) is commonly hosted in Sn-rich deposits but rarely reported in Sn-poor deposits. However, an In-rich and Sn-poor skarn deposit, the Qibaoshan Cu-Zn-Pb deposit, has been identified in south China. Geochemical analyses were undertaken on 23 samples representing the following mineral assemblages: sphalerite-pyrite, pyrite-chalcopyrite, pyrite-sphalerite-galena-chalcopyrite, pyrite, magn...
متن کاملبررسی کانی سازی اسکارن مزرعه، شمال اهر، با تاکید بر مطالعه میانبارهای شاری
The emplacement of Oligo-Miocene age Sheyvardagh intrusive body within the older carbonate and volcanoclastic rocks is responsible for contact metamorphism and creating of Mazraeh deposit in epidote - garnet exoskarn of Western Alborz- lesser Caucasus metallogenic belt. Mineralogical paragenesis consist of magnetite, pyrite, chalcopyrite, bornite, covellite, hematite, goethite and malachite and...
متن کاملهم نهشت کردن زئولیت در اثر تغییر فاز گرمابی کائولینیت تحت تاثیر محلول‌های باریم و سدیم‌دار
Gazu copper deposit is located in the boundary of Tabas and Lut block, 65km southeast of Tabas and 15km southwest of Deyhouk. The dominant lithology in the area consists of Shotori dolomite and limestone and Shemshak shale and sandstone. Intrusive rocks with intermediate composition are widespread and numerous in the area. They consist of diorite, monzonite, and quartz monzonite to granite. Mi...
