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...

Gasht metamorphic complex is situated in the Talesh mountains of western Alborz range. This metamorphic complex consists mainly of metapelite and metabasite. Metabasites display metamorphic conditions of amphibolite and greenschist facies. Mineralogical paragenesis of greenschists are amphibole, feldspar and epidot and clinopyroxene occures as accessory minerals. The amphibolites of Gasht metam...

Tanbour metamorphic complex east of Sirjan is compoused of metasediments and metabasic rocks. Petrofabric study of this complex shows two metamorphic and two deformational phases. Chemical studies of index minerals indicate that second phase of metamorphism occurred with a degree up to lower amphibolite facies. Mineral assemblage of first phase are biotite, muscovite and garnet while staurolite...

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...

Soltanabad metamorphic complex cropped out in the ophiolitic range of NE Sabzevar. There is a distinct gneissic body exposed in this complex which is associated with metabasite, serpentinite and adakitic intrusions. Quartz, albite, epidote, amphibole, garnet and chlorite are the rock forming minerals of gneissic samples. Based on abundances of light and dark minerals, different types of felsic,...

Surian volcano–sedimentary complex located on the eastern edge of the Sanandaj-Sirjan metamorphic zone, southwest Iran. Graphite schist is the most abundant lithological facies in this area. Due to the high grade of the graphite ore (up to 50%), the exploitation of the ore is economically valuable. Gangue minerals include quartz, muscovite, plagioclase, clinochlore, zircon and ilmenite. The occ...

Do-Chah metamorphic-igneous complex is one of the Iranian crystalline basement complexess which is located in the SE Shahrood in northern edge of Central Iran structural zone. This complex includes a wide compositional range of metamorphic rocks such as metabasite, metapelite, metacarbonate and metapsammite, and meanwhile is host of leucogranite and biotite granite intrusions. Protolith of meta...
