Mafic Granulites in the Crystalline Core of the Neybaz Complex
IntroductionFormation and evolution of the continental crust is one of the fundamental subjects in Earth sciences studies, as these processes usually occurred during the Archean and Proterozoic (e.g., Condie, 1980; Taylor and McLennan, 1981). Regions with high-grade metamorphic rocks such as…

Diachronous Eocene-Oligocene granitoid magmatism in the southeastern part of the Urumieh-Dokhtar magmatic arc, Mardehak area, Jebal-e-Barez, Jiroft
IntroductionThe Zagros orogeny occurred through four main geodynamic events of the Wilson cycle, leading to the formation of the Neotethys oceanic basin: (i) intracontinental rifting in the Carboniferous, (ii) oceanic basin development in the Permian–Triassic, (iii) subduction of oceanic…

Tourmaline geochemistry in the granitoids of the Sanandaj–Sirjan Zone (A case study of Astaneh and Aligudarz granitoids)
IntroductionTourmaline exhibits a broad range of chemical variability (Hawthorne and Henry, 1999). This diverse and complex chemistry reflects a clear genetic link between tourmaline and the environment from which it crystallized. Such a relationship provides a reliable and robust indicator for…
