Crustal evolution of NW Iran: Cadomian arcs, archean fragments and the cenozoic magmatic flare-up
(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 ...
Tracking the birth and growth of Cimmeria: Geochronology and origins of intrusive rocks from NW Iran
(Elsevier, 2020)
New geochronological and geochemical data for Late Neoproterozoic to Mesozoic intrusive rocks from NW Iran define major regional magmatic episodes and track the birth and growth of one of the Cimmerian microcontinents: the ...
The Paleogene ophiolite conundrum of the Iran-Iraq border region
(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
(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) ...
