Structural and metamorphic evolution of the southern Sanandaj-Sirjan zone, southern Iran

International Journal of Earth Sciences, 2022
The southern Sanandaj-Sirjan Zone (SSZ) forms the core of the Zagros orogen and consists of a stack of four major tectonic units, all of which were thrust southwestward over the Neyriz ophiolites. Precambrian and early Paleozoic rocks were affected by high-grade metamorphism, whilst the late Paleozoic (Carboniferous and Permian) and Mesozoic rocks are ...

Geochemistry, petrogenesis, and tectonic setting of the Almogholagh batholith in the Sanandaj–Sirjan zone, western Iran

Journal of African Earth Sciences, 2017
Abstract The Almogholagh batholith in the northern Sanandaj-Sirjan magmatic–metamorphic zone comprises three intrusive bodies (gabbroic diorite, quartz syenite, and quartz monzonite) that were generated during the northeastward subduction of Neo-Tethys beneath the Iranian sector of the Eurasian plate.
