Detailed microstructural analysis has been conducted in the Ghandab metamorphic Complex, which is one of the most important high temperature – low pressure regional contact metamorphism studied areas in Iran. Textural evidence suggests the sequence of growth of minerals with increasing metamorphic grade and during development of a crenulation foliation. The sequence of mineral growth is conside...

Pressure and temperature of metamorphism in the Mahneshan area were estimated in order to determine the type of metamorphism and tectonic setting of the rocks. Biotite, muscovite, plagioclase, garnet, quartz, andalusite and staurolite minerals are crystallized together in metapelites in the regional metamorphic rocks of southwest Mahneshan. Chemistry of coexisting minerals is studied using micr...

The study area is located in Hamedan Province adjacent to Alvand plutonic body in the Sanandaj-Sirjan zone. Various contact and regional metamorphic rocks, from low to high grade exist in contact of Alvand plutonic body including schists, hornfelses and migmatites. Kyanite-bearing rocks volumetrically are not widespread but occur as various outcrops (in migmatite, hornfels and quartz-kyanite ve...
