Investigation of genesis and fluid origin in Noghduz gold bearing quartz veins, East Azarbaijan Province, northwest of Iran
The Noghduz prospecting area, as a part of the Arasbaran metallogenic zone is located about 20 km east of Ahar, East-Azarbaijan Province. The mineralization host rocks are andesite-trachy andesite with the age of Late Eocene. The hydrothermal alterations exposed in this area are silicic, argillic, and propylitic. Pyrite is the main hypogene sulfide mineral which is accompanied by lesser amou...
متن کاملCharacteristics of the ore- bearing quartz veins using fluid inclusions, Andarian, NW Iran
Andarian area is located north of Tabriz city, north west Iran, and tectonically is a part of Ahar-Arasbaran magmatic belt. Geology of the area includes Miocene shallow pluton, Cretaceous flysch-type sediments, metamorphic rocks )hornfels and skarn( and volcanic rocks. Mineralization occurred in two stages: primary and secondary. The primary ore minerals include Au, pyrite and stibnite. Malachi...
متن کاملInvestigations of gold-sulfide mineralization and microthermometry within quartz veins/veinlets in the Gharehchay area, south of Tikmehdash, East-Azarbaidjan province, NW Iran
The gold-bearing prospect area at Gharehchay is located in about 2 km south of Tikmehdash, East-Azarbaidjan, NW Iran. The host rocks of the gold-bearing quartz veins/veinlets are principally Eocene andesites and upper Eocene-Oligocene felsic intrusive body (granite to alkali granite). Wall rocks alteration haloes developed around the veins/veinlets are mainly of silicic, phyllic, phyllic-argill...
متن کاملInvestigation of mineralogy and geothermometry of quartz and tourmaline veins at the Baghu area, southeast of Damghan
The Baghuo gold mine (Kuhzar) is located about 100 km S-SE of Damghan. The area is part of Torud- Chahshirin volcano- plutonic belt. The hosts of quartz – tourmaline veins are mainly granite, granodiorite and volcanic rocks such as andesite and dacite. Mineralization occurs as a copper- gold bearing silica vein. Quartz, pyrite, chalcopyrite, gold, hematite, malachite, azurite, covellite and Fe...
متن کاملInfrared Spectroscopic studies on the Mobility of Metamorphic Fluid in Quartz veins of Dharwar Craton
The thermal induced variations of water inclusions in their OH stretching mode region were probed in quartz veins from Dharwar Craton, India, using fourier transformed infrared spectroscopy (FTIR) in the temperature range 25 to 300 oC. All the inclusions have composition H2O-NaCl-CO2. The peak positions monotonously shift to higher wavenumbers with increasing temperature with slopes of 0.23 and...
