the qom formation in southwest kashan in sanandaj-sirjan fore arc basin has a thickness of 190 meters and is composed of medium to thick and massive bedded limestone, marly limestone, sandy limestone, marl and coglomerates. study of these deposits led to recognition of nine microfacies related to a carbonate platform. the high presence of perforate foraminifera in most of the recognized microfa...
The results of microprobe analysis indicate four different kinds of amphiboles in Astaneh pluton and its subvolcanic rocks in the Sanandaj-Sirjan zone. The composition of these amphiboles in this area are magnesio hornblende in tonalite and quartz dioritic enclaves, actinolite in granodiorite and monzogranite, pargasite in dacititc enclaves and anthophillite in one tonalitic sample formed by re...
The study area is located in northern part of metamorphic belt of Sanandaj-Sirjan in east of Hamedan Batolith. This area is mainly composed of regional metamorphic rocks, such as staurolith, andalusite, silimanite and garnet bearing mica schists and slates, with nearly NW-SE trend. The age of these rocks (tectonites) are Pre-jurassic and have experienced two stages of deformation during du...
West and southwest of Razan igneous rocks are located in the Hamedan Province in the Sanandaj- Sirjan zone, west Iran. According to petrography and chemical studies, these rock bodies are composed of diorite, gabbrodiorite, monzonite, quartz- monzonite, andesite and andesibasalt. The results of geochemical analysis show that these rocks belong to a cal- alkaline magma series. The geochemical c...
The volcanic rocks with the Plio-Quaternary age, are exposed in the northern part of the Sanandaj-Sirjan zone, in northwest Urmia. The main mineral phases are olivin + clinopyroxene ± plagioclase, that are present as both phenocrysts to microcrystalline with other minor minerals. The dominant textures of these rocks are porphyry, microlithic porphyry, hyalo-porphyry, glomeroporphyritic and vesi...

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...
The Qalaylan pluton of Late Jurassic age is composed of intermediate and felsic rocks that crop out in the northern Sanandaj-Sirjan Zone. A body is comprising alkaline, high K, Ferroan A1-type rocks with contrasting aspects; whiles, Nd-Sr primitive isotopic composition consistent with a mantle source. On the other hand, inherited zircon cores (with a range of 230 – 2700 Ma) and elevated Nd mode...
