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 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 Gol-Gohar metamorphic complex is located about 55 km southwest of the Sirjan and is part of east Sanandaj-Sirjan zone. The rocks units are metamorphosed in greenschist and upper amphibolite facies with age of Middle Jurassic which consists of metapelitic (mica-schists and gneisses), metabasitic and metacarbonatic rocks. Geochemical studies indicate that the precursor sediments of the metape...

Amphibolites are one of the metamorphic rock units of Jandaq ophiolite and exposed in a considerable volume. These rocks are metamorphism products of basalts, pillow lavas and diabasic dikes of Jandaq ophiolite. Amphibolites contain amphibole, plagioclase, garnet, alkali feldspar (orthoclase), magnetite, biotite, muscovite, sphene, quartz, epidote and calcite minerals. These rocks contain very ...

Amphiboles are one of the major minerals in metabasic rocks in greenshist to upper amphibolite facies. Amphiboles have variable chemical composition, therefore, various elements with different ionic charge and radius can intering into their structure that occupy special mineralogical sites. There are some elements in amphiboles which are sensitive to the changes of pressure and temperature. The...
