The granite-gneiss body of  Abadchi area (vicinity of Zayandeh-Rud dam) is a part of Sanandaj-Sirjan tectonic zone. The mineralogical composition of the granite- gneisses contains quartz, K-feldspar, plagioclase, biotite and muscovite and minor minerals of opaque, zircon, amphibole and allanite. The granite-gneiss rocks have been influenced by deformation dynamics and weakly Na-metazomatism. Ge...

Due to the dryness of the weather in most parts of Iran and the lack of sufficient rainfall in more than six months of the year in most places, resulting in the seasonality of rivers and the lack of access to water, various arrangements for fresh water supply in the dry seasons has been established. The construction of the AB ANBAR (water reservoir and cistern) is one of innovative ways to supp...

The studied area, as Ykeh-Chah unit, is a part of Golpayegan magmatic and metamorphic complex in Sanandaj-Sirjan structural zone. The unit consists of mylonitized and high- grade metamorphic rocks, including biotite-gneiss, biotite-garnet-gneiss, amphibolite and orthogneiss. The biotite gneiss and the biotite garnet gneiss have partly been migmatitized. They show various structures such as stro...

Bondono granite-gneiss body is located in the core of Toutak anticline, located 200 km NE of Shiraz. This granitoid mass, which is a part ofToutak metamorphic complex, is exposed on the Sourian sheet. Petrological studies determined that the mentioned rocks are placed in orthogneiss field. Based on current studies, the geochemical, tectonic setting and geochronology characteristics of the Bondo...
