Crustal evolution of NW Iran: Cadomian arcs, archean fragments and the cenozoic magmatic flare-up
Moghadam, Hadi Shafaii; Griffin, William L.; Li, Xian-Hua; Santos, Jose F.; Karslı, Orhan; Stern, Robert J.; Ghorbani, Ghasem; Gain, Sarah; Murphy, Rosanna; O'Reilly, Suzanne Y. (Oxford Univ Press, 2017)The Cadomian orogen of NW Iran includes a series of metamorphic rocks with zircon U-Pb ages between ca 562 and 505 Ma (Ediacaran to middle Cambrian). the Ediacaran-Cambrian basement is intruded by a series of Late Eocene-Late ... -
A Jurassic volcanic passive margin in Iran and Turkey
Azizi, Hossein; Stern, Robert J.; Kandemir, Raif; Karslı, Orhan (Wiley, 2022)Broadly similar Early to Middle Jurassic stratigraphic sequences including bimodal igneous rocks of the Sanandaj–Sirjan Zone of Iran and the Sakarya Zone of Turkey suggest that these formed in a common tectonic setting in ... -
The Paleogene ophiolite conundrum of the Iran-Iraq border region
Moghadam, Hadi Shafaii; Li, Qiu-Li; Stern, Robert J.; Chiaradia, Massimo; Karslı, Orhan; Rahimzadeh, Bahman (Geological Soc Publ House, 2020)New and compiled geochemical, isotopic and geochronological data allow us to propose a new explanation for Paleogene oceanic magmatic rocks along the Iran-Iraq border. These rocks are represented by a thick pile (>1000 m) ... -
Zircon U-Pb, geochemical and isotopic constraints on the age and origin of A- and I-type granites and gabbro-diorites from NW Iran
Moghadam, Hadi Shafaii; Li, Qiu-Li; Griffin, William L.; Stern, Robert J.; Chiaradia, Massimo; Karslı, Orhan; Ghorbani, Ghasem; O'Reilly, S. Y.; Pourmohsen, Mehrdad (Elsevier, 2020)The continental crust of NW Iran is intruded by Late Cretaceous I-type granites and gabbro-diorites as well as Paleocene A-type granites. SIMS and LA-ICPMS U-Pb analyses of zircons yield ages of 100-92 Ma (Late Cretaceous) ...
