An exotic block of garnet-bearing schist has been found at the boundary between Early Triassic Takinosawa Unit Nedamo Belt and Jurassic Nakatsugawa Complex North Kitakami Belt, NE Japan. This is only second discovery schists in Belt; previously identified occur early Carboniferous Tsunatori units Belt. The characterized by a mineral assemblage garnet + phengite epidote albite quartz titanite. P...
کمپلکس دگرگونی خواجو در جنوب شرق زون سنندج-سیرجان و کمپلکس دگرگونی سورسات در شمال غرب زون سنندج-سیرجان برونزد دارند. در این کمپلکسها کانی آمفیبول در سنگهای دگرگونی مانند گارنت آمفیبولیتها و آمفیبول شیستها حضور دارد. انواع فابریک آمفیبولها در این سنگها شامل نماتوبلاستی، برشی، کاتاکلاستی، رشد تجمعی و پاپیونی با طویل شدگی در امتداد محور c میباشند. حالتهای تجمعی و پاپیونی کانی آمفیبول، در ا...
Gol-e-Gohar and Rutchun metamorphic complexes in south-east of Sanandaj-Sirjan metamorphic zone contain alternation of meta-sedimentary, meta-basites and impure meta-limestone that have been affected by different metamorphic events and deformational phases. In the first metamorphic event that was associated with the first deformational phase, muscuvite, biotite and garnet minerals were formed a...
Garnet bearing staurolite schists comprise an important part of regional metamorphic succession in the Hamedan area (north of the Sanandaj-Sirjan zone). These rocks contain staurolite and garnet porphyroblats that lie in a matrix which is composed of biotite, muscovite and quartz. The staurolites in Fe-rich and show little chemical composition diversities. Almandin is the most important compone...
Bolandparchen metamorphic complex located in the NW Zanjan city and is at the border of Central Iran and Sanandaj-Sirjan Zones. The study area contains different schists, impure marble and metsandstone that intruded by granitic bodies in the central and northern parts. Central part of Bolandparchen complex cut by NW to SE fault. Petrographic study, whole rock analysis, microprobe analyses and B...
The Tauride Belt Ophiolites in southern Turkey are located on both sides of the E–Wtrending, Mesozoic Tauride carbonate platform. They comprise the Lycian, Antalya, Beyşehir, Mersin, Alihoca and Pozantı-Karsantı ophiolites from west to east. Each ophiolite has a metamorphic rock unit either at the base of the peridotites or in the mélange units. The metamorphic sole rocks generally consist of a...
The Anjir Khajeh area is located in the southern part of Sanandaj-Sirjan metamorphic belt in northwest of Golgohar iron mine. The rock units of the region include metabasites, metasediments, igneous and sedimentary rocks. Metasedimentary rocks containing mica-schist, garnet schist, and garnet staurolite schist, having metamorphosed into greenschist facies and amphibolite facies. Garnet mineral ...
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...
