East Salmas Metabasites, as one of the most extensive units of the metamorphic complex, is located in the northwest of Sanandaj-Sirjan zone. These metabasites are mainly composed of amphibolite and green shist, alternating with geniss, metadiorite and marble metamorphic rocks. Metabasites are structurally oriented and mass, and grain size varies from small to medium. According to microscopic st...

The Qatruyeh iron occurrences are located in the eastern edge of the Sanandaj-Sirjan metamorphic zone, southwestern Iran (at 50 Km northeastern of Neyriz), and are hosted by a Late Proterozoic to Early Paleozoic sequence which is dominated by metamorphosed carbonate rocks. The Iron ores occur as layered, massive and disseminated magnetite and in lesser amount as hematite-bearing veins and veinl...

The Deh-Sard area IS located about 90 km south of 8aft in the Kerman province, situated in southern part of Sanandaj-Sirjan zone. It consists of interm ittent lava flows (basalt, basaltic andes ite and trachyandesite), pyroclastic rocks (various types of tu ffs and paloebereccias) and sedimentary rocks (lime stones and shales) of Jurassic age. The Deh-Sard lava flows are essentially compo...

The metabasite rocks from north of Shahrekord, which is a part of structural zone of Sanandaj-Sirjan, are undergone medium temperature – high pressure metamorphism (eclogite facies). These rocks then were subjected to a retrograde metamorphism (amphibolite facies). A distinct compositional zoning is preserved in fresh garnets which are formed during eclogite facies. The compositional or growth ...

The granitic gneisses of Abadchi village is located in the North of Zayandeh-Rud dam, where the area is a part of Sanandaj-Sirjan Zone. The mineralogical composition of the rocks is composed of quartz, plagioclase, K-feldspar, biotite, amphibole, muscovite, zircon, titanite and allanite. Quartz crystals, as the most abundant mineral constituents of these rocks, display the different conditions ...
