Metapelites of the Do Chah complex (SE Shahrood) are composed of micaschist, garnet micaschist, chloritoid schist and garnet-bearing gneiss. In the highest degree of metamorphism, metapelites have been affected by partial melting, resulting as granitization. A significant part of these rocks, imposed by compressional tectonic regime and show typical evidence of plastic deformation and intensive...

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 ...

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...

Metamorphic rocks of the Hamadan region have experienced regional and also contact metamorphism (due to intrusion of gabbro, diorite and granitic bodies), therefore, their mineral assemblages have formed in multiple stages. Evidence of regional metamorphism (M) and contact metamorphisms at the contact of gabbros (M’1) and porphyroid granites (M’2) are separatable, hower At the contact of h...
