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...

In this paper, metamorphic conditions (T, P and fluid composition) in greenschist to amphibolite facies transition zone are investigated using textural evidence, compositions of the minerals and phase diagrams. Metabasits from the south of Kordestan province were metamorphosed from sub-greenschist to upper amphibolite facies. Field observations and petrography studies show that there are some r...

Lower Paleozoic metabasites of south Chah Palang are located in north of the Yazd block in Central Iran with limited distribution and are associated with Doshakh metamorphites. Metabasites divided in to two portions: metavolcanics, and metagabbro, amphibolite and metadiabase masses. Metavolcanic with basaltic composition are presented by foliation and vesicles filled by calcite. Amphibole, plag...

Sarkobeh area is located north of Khomein in the most unstable tectonic zone (Sanandaj - Sirjan). In the area, exposed rocks are limestone, quartzitic rocks and  gabbro (alkaline gabbro). The main minerals in rocks are, plagioclase, clinopyroxene and opaque, while the accessory minerals include biotite, amphibole, quartz, apatite, zircon as and chlorite and prehnite - pumpellyite are  represent...
