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.

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.

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 ...

Bolorian and Kubergandian stages of the Permian in the Sanandaj-Sirjan zone of Iran
Stratigraphy and Geological Correlation, 2008Sections and fusulinids of the Bolorian (presumably) and Kubergandian (lower part) stages in the Sanandaj-Sirjan tectonic zone are described. Two fusulinid assemblages are distinguished in a most complete section near Sirjan. The lower one is represented by Skinnerella, Paraleeina, and relatively primitive Misellina forms, whereas Armenina ...

Geochemistry of metabasites in the north of the Shahrekord, Sanandaj-Sirjan Zone, Iran
Neues Jahrbuch für Mineralogie - Abhandlungen, 2006Metabasites are exposed in the north of Shahrekord that is a part of the structural zone of Sanandaj-Sirjan in south- western Iran. The metabasites are composed mainly of eclogites, amphibolites and garnet amphibolites. We have conducted a geochemical study of metabasites in order to determine their protolith nature and geodynamic setting.

The continuation of the Kazerun fault system across the Sanandaj–Sirjan zone (Iran)
Journal of Asian Earth Sciences, 2009Abstract The Kazerun (or Kazerun-Qatar) fault system is a north-trending dextral strike-slip fault zone in the Zagros mountain belt of Iran. It probably originated as a structure in the Panafrican basement. This fault system played an important role in the sedimentation and deformation of the Phanerozoic cover sequence and is still seismically active.

Petrogenesis of granitic unit of Naqadeh complex, Sanandaj–Sirjan Zone, NW Iran
Arabian Journal of Geosciences, 2009The granitic unit is a component of the Naqadeh plutonic complex, NW of Sanandaj–Sirjan Zone (NW Iran). This unit is composed of high-K calc-alkaline, slightly peraluminous (ASI = 1.12–1.17) evolved monzogranites. These monzogranites have 41.85 ± 0.81 Ma (zircon U–Pb sensitive, high-resolution ion microprobe (SHRIMP) age) with two inherited zircon ages
