Episodic subduction initiation triggered Jurassic magmatism in the Sanandaj–Sirjan zone, Iran
Lithos, 2021Abstract The Zagros suture zone in Iran is part of the Tethyan orogenic belt that records convergence between the Eurasian and Arabian plates during the Mesozoic-Cenozoic. Prior to collision, which may have initiated in the Late Eocene-Early Oligocene, much of the convergence was accommodated by the Late Triassic-Early Jurassic subduction of the ...

Deformation Mechanisms of Darreh Sary Metapelites, Sanandaj‒Sirjan Zone, Iran
Geotectonics, 2018The Darreh Sary metapelitic rocks are located in the northeast of Zagros orogenic belt and Sanandaj-Sirjan structural zone. The lithological composition of these rocks includes slate, phyllite, muscovitebiotite schist, garnet schist, staurolite-garnet schist and staurolite schist.

Structural and metamorphic evolution of the southern Sanandaj-Sirjan zone, southern Iran
International Journal of Earth Sciences, 2022The 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 ...

A new tectonic scenario for the Sanandaj–Sirjan Zone (Iran)
Journal of Asian Earth Sciences, 2006Abstract Recent geochemical studies of volcanic rocks forming part of the ophiolites within the Zagros and Naien-Baft orogen indicate that most of them were developed as supra-subduction ophiolites in intra-oceanic island arc environments. Intra-oceanic island arcs and ophiolites now forming the Naien-Baft zone were emplaced southwestward onto the ...

Documentation of the Sirjan Orocline in the southeast Sanandaj-Sirjan Zone, Iran
Journal of Mountain Science, 2020At the southeastern part of the Sanandaj-Sirjan Zone of Iran, a group of structural elements outline a large-scale arc curvature around a vertical axis. This curvature comprises several elongated structural elements and their dividing faults, axialfold traces, layering, and foliation.

Metamorphism and deformation of golpayegan metapelitic rocks, Sanandaj-Sirjan Zone, Iran
Petrology, 2012The metapelitic schists of the Golpayegan region can be divided into four groups based on their mineral assemblages: (1) garnet-chloritoid schists, (2) garnet schists, (3) garnet-staurolite schists, and (4) staurolite-kyanite schists. Paleozoic pelagic shales experienced progressive metamorphism and polymetamorphism from greenschist to amphibolite ...

Cretaceous subduction-related volcanism in the northern Sanandaj-Sirjan Zone, Iran
Journal of Geodynamics, 2008Cretaceous volcanic rocks (SCV) are widely developed in the northern part of the Sanandaj-Sirjan Zone, northwest Iran. Based on the mineralogy, texture and geochemical composition these rocks are divided in two main groups, the first and main one situated in the central part of the study area and the second one in the northeast.

Cretaceous–Tertiary convergence and continental collision, Sanandaj–Sirjan Zone, western Iran
Journal of Asian Earth Sciences, 2003Abstract The Sanandaj–Sirjan Zone contains the metamorphic core of the Zagros continental collision zone in western Iran. The zone has been subdivided into the following from southwest to northeast: an outer belt of imbricate thrust slices (radiolarite, Bisotun, ophiolite and marginal sub-zones, which consist of Mesozoic deep-marine sediments ...

Saqez–Sardasht Goldfield, North Sanandaj‐Sirjan Zone, Iran: A Tectono‐Metallogenic Synthesis
Acta Geologica Sinica - English Edition, 2020AbstractThe Sanandaj–Sirjan Zone (SSZ), as the metamorphic‐magmatic core of the Zagros Orogen in southwestern Iran, contains several styles of gold deposit of Phanerozoic age. The northern SSZ includes an ENE‐trending goldfield belt. This area that encompasses the main orogenic gold deposits, e.g., Qolqoleh, Kervian, Qabaqhlujeh, and the Barika VMS ...

Petrology of eclogites from north of Shahrekord, Sanandaj-Sirjan Zone, Iran
Mineralogy and Petrology, 2007Metabasic rocks were recently found within a ductile shear zone in the north of Shahrekord, being a part of the structural zone of Sanandaj-Sirjan, SW Iran. The rocks give evidence of a so far unrecognized eclogite facies metamorphic event and testify to high pressure metamorphism in the Sanandaj-Sirjan Zone, near the Main Zagros Reverse Fault, which ...
