Tourmaline chemistry in Malayer-Boroujerd-Shazand, (Sanandaj-Sirjan Zone)
The Malayer-Boroujerd-Shazand district (approximately 70 km long) is located in the Sanandaj-Sirjan zone with NW-SE trending, and consist mainly of hornfels, schist, phyllite, migmatite, granite and granodiorite which contain numerous pegmatite and aplitic dykes. Among these rocks, granodiorite, hornfels and schist are main host rocks for quartz, feldspar, muscovite and tourmaline bearing pegma...
متن کاملChemical Variation of Tourmaline and Source of Hydrothermal Solutions in Nezam Abad W-(Sn) Ore Deposit, Sanandaj-Sirjan Zone, West-Central Iran
Tourmalinization characterizes the most pervasive alteration type in the Nezam Abad ore deposit, west-central Iran. It delineates high-temperature centers of mineralization and together with quartz and cassiterite form inner parts of the alteration halo. The composition of tourmalines plots mostly along and between the proton and alkali-deficient end members. Tourmaline in quartzdioritic host i...
متن کاملMetamorphic evolution of high-pressure Quartz Schists in the Chadegan metamorphic complex, Sanandaj-Sirjan zone, Iran
The Chadegan metamorphic complex is a WNW-ESE- trending antiformal structure located in Sanandaj-Sirjan structural zone, Iran.The inner core of the structure is made of orthogneiss, containing eclogitic lenses. Schists and marbles lie structurally above theorthogneiss and crop out in the external limbs of the antiformal dome. Two main deformational episodes have been documented in theschists an...
متن کاملAn Investigation on the Mineralogy and Paragenetic Relationship of Buin Miandasht Skarn, Sanandaj-Sirjan Zone
The study area is located in northwest of Isfahan, 25 km northwest of Daran. Buin-Miandasht intrusive rocks consist of granite and granodiorite. Based on geochemical diagrams, these granitoids are I -type calc-alkaline and evolved in volcanic arc environments. The Buin-Miandasht intruded into the metamorphic basement (Paleozoic?) and a small skarn and hornfels occurred along its contact. Based ...
متن کاملpetrography, mineral chemistry and geothermobarometry of andalusite- bearing schists north of azna (northern sanandaj-sirjan zone, iran)
introduction the area studied is located north of azna (lorestan province) in a small portion of the sanandaj – sirjan structural zone (mohajjel et al., 2003).this area is part of the zagros orogenic belt, formed by the opening and closure of neotethyan ocean. from ne to sw, it consists of three parallel tectonic regions: the orumieh-dokhtar magmatic belt, the sanandaj-sirjan structural zone an...
