[ 1 ] - Fe-Ti Oxide Minerals Geothermometry and Oxygen Fugacity at the Dar Gaz Anomaly, Kahnuj
In the southeast of Iran, titaniferous magnetite deposits associated with the gabbro rocks occur in Kahnuj ophiolitic complex. Mineraloghraphy studies have revealed the primary and secondary ore mineral consist of titanomagnetite, ilmenite, hematite, goethite, martite, pyrite, chalcopyrite, pyrrhotite and silicate minerals (plagioclase, pyroxene, hornblende, olivine, alkali feldspar). Trellis-s...
[ 2 ] - Petrography, geochemistry, magmatic evolution and tectenomagmatic setting of igneous rocks associated with Nikuyeh epithermal mineralization (west of Qazvin)
The Nikuyeh district is located south of the Tarom-Hashtjin metallogenic province in Western Alborz. Oligo-Miocene subvolcanic intrusion and Mid-Eocene volcanic rocks with composition of dacite to andesite are main igneous settings associated with Nikuyeh polymetallic epithermal ore mineralization. Igneous phase in the Nikuyeh district are porphyritic granodiorite, monzodiorite, quartz monsonit...
[ 3 ] - Mineralogy and geochemistry of pegmatitic dykes in the Boroujerd-Nezam Abad zone with respect to trace and rare earth elements mineralization
Boroujerd-Nezam Abad zone widespread along NW-SE trend in part of Sanandaj-Sirjan zone. Borujerd-Nezam zone consists of hornfels, schist, phyllite, migmatite, granite and granodiorite rock types. Metamorphic (hornfels and schist) and igneous (granitoids) rocks are known as host pegmatitic dykes. Quartz, feldspar, muscovite and tourmaline are the most common pegmatite, and mica are as muscovite ...
