Ghazan-Khanik complex is a small mafic-ultramafic intrusive body with Permian age at the extremity of NW of the Sanandaj-Sirjan zone, has intruded into the Precambrian metamorphic rocks. Field studies, geochemistry mineral compositions and assemblages of them demonstrate this complex has four lithological zones. The lower zone of non-layered gabbro is the fine-grain gabbronoritic component and ...

The plutonic bodies in northeast of the Sonqor area is a small part of the Sanandaj-Sirjan zone. According to the field and microscopic observations, the study area is composed of two major units; massive rocks (hornblende gabbro, intermediate and felsic rocks) and dikes (pyroxene gabbro). Mineralogical and geochemical studies show that this granitoide compelex is I-type, calk-alkaline and meta...

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 study area is located in northwest of Isfahan, 25 km northwest of Daran. Buin-Miandasht intrusive rocks consist of granite and granodiorite. Based on geochemical diagrams, these granitoids are I -type calc-alkaline and evolved in volcanic arc environments. The Buin-Miandasht intruded into the metamorphic basement (Paleozoic?) and a small skarn and hornfels occurred along its contact. Based ...

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...
