Geological Journal, Volume 60, Issue 4, Page 793-806, April 2025.This work documents how the texture and composition of metamorphic garnet represent a valuable petrological archive capable of deciphering complex thermobaric histories. ABSTRACT In the central sector of the Sanandaj‐Sirjan zone of Iran, the Triassic‐to‐Jurassic ‘Hamedan Phyllites’ metamorphic complex shows a polymetamorphic evolution characterised by ...

A new tectonic scenario fro the Sanandaj-Sirjan Zone (Iran)
Journal of Asian Earth Sciences, 2006 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.

Petrological Evolution of the Upper Mantle Beneath the Southern Sanandaj-Sirjan Zone: Evidence from Kuhshah Peridotite Massif, Southeast Iran [PDF]
Journal of Sciences, Islamic Republic of Iran, 2014 The Kuhshah ultramafic complex is located in the south-east of Sanandaj-Sirjan metamorphic zone, near the probable remnants of Neotethys plate in Iran. It consists of highly depleted harzburgites, dunites, chromitite bands and altered gabbros.

Origin of tourmaline in micaschists of Gol-e-Gohar metamorphic complex from south-eastern Sanandaj-Sirjan Zone (Baft, Kerman Province) [PDF]
پترولوژی, 2018 In Gol-e-Gohar micaschists from south-east Sanandaj-Sirjan Zone (Kerman province), there are tourmaline crystals which are enriched in Mg and Na (Mg: 1.830 a.p.f.u and Na: 0.680 a.p.f.u), and so, they are dravite in compositions belonging to alkaline ...
