Geological, fluid inclusion and isotopic characteristics of the Gardaneshir Zn–Pb deposit, Central Iran
Gardaneshir Pb–Zn deposit is hosted by dolomitic carbonates which is located in the SW Ardestan, central Iran. Ore body is stratabound type in this deposit. Primary ores in this type are composed of sphalerite, galena, barite and quartz with massive, banded, veined and disseminated structures. Evaluation of ore-grade at the Gardaneshir Pb-Zn deposit, based on chemical analysis which indicates a...
متن کاملMineralogical, alteration and fluid inclusion studies of the mineralization index at Yeylaghe Gharachi, northwest of Ahar, NW Iran
The mineralization index of Yeylaghe Gharachi, as part of Arasbaran metallogenic belt, is located about 25 km northwest of Ahar, East-Azarbaidjan Province, NW Iran. The host rocks of this index consist of composite intrusive rocks with lithologic compositions of granite, quartz monzonite, granodiorite and diorite of Oligocene and Oligo-Miocene age. The alteration zones in this area are mainly p...
متن کاملGeochemical and isotopic (Nd and Sr) constraints on elucidating the origin of intrusions from northwest Saveh, Central Iran
Three intrusive granitoid bodies from northwest Saveh, central Iran, are embedded in volcanic sedimentary rocks of the Eocene,forming isolated small outcrops: Khalkhab quartz monzodioritic units (SiO2: ~52-57 wt %) to the northwest, Neshveh granodioriticunits (SiO2: ~62-71 wt %) to the northeast, and Selijerd granodioritic units (SiO2: ~63-69 wt %) to the southeast. The Khalkhab unit iscomposed...
متن کاملFluid Inclusion Studies on Quartz Veinlets at the Yeylagh-e-Gharechi Porphyry Copper Deposit, Arasbaran Metallogenic Belt, Northwestern Iran
Yeylagh-e-Gharechi porphyry copper deposit is located in the Arasbaran metallogenic belt at northwestern Iran, 25 kilometer of Ahar. Porphyry mineralization at the Yeylagh-e-Gharechi deposit occurred in post-Oligocene quartz monzonite and monzonite bodies which was hosted by Eocene volcanic rocks. Mineralization occurred as veins, veinlets and dissemination in hypogene zone. Supergene zone has ...
متن کاملthe nature of hydrothermal fluids in the kahang porphyry copper deposit (northeast of isfahan) based on mineralography, fluid inclusion and stable isotopic data
introduction the kahang cu- mo deposit is situated approximately 73 km northeast of isfahan. asadi (2007) identified a geological reserve of 40 mt (proven reserve) grading at 0.53 cu, 0.02 mo and estimated reserve of 120 mt. all the rock types in the region have been subjected to hydrothermal solutions which gave rise to three different alteration facies. the dacite and rhyodacite volcanic rock...
