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 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 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 کاملPetrological Evolution of the Upper Mantle Beneath the Southern Sanandaj-Sirjan Zone: Evidence from Kuhshah Peridotite Massif, Southeast Iran
The Kuhshah ultramafic complex is located in the south-east of Sanandaj-Sirjan metamorphic zone, near the probable remnants of Neotethys plate in Iran. It consists of highly depleted harzburgites, dunites, chromitite bands and altered gabbros. The ultramafic parts have been intruded by numerous clinopyroxenite dykes and veins. In the harzburgites, there are different generations of olivine, ort...
متن کاملStudy of the zircon morphology and internal structures as a tool for constraining magma source: example from granitoid bodies in the northern Sanandaj Sirjan zone (SW Saqqez)
The granitic intrusives in southwest Saqqez are located in the northern Sanandaj Sirjan zone. These granites can be divided into mesocratic and leucocratic granites. The external morphology and internal structures of zircon from these granites have been investigated employing the classic Pupin method supplemented by electron microscope analysis. The zircon crystallization is a function of tempe...
