Cenozoic temporal variation of crustal thickness in the Urumieh-Dokhtar and Alborz magmatic belts, Iran
(Elsevier, 2021)
We present regional variations of whole-rock Sr/Y and (La/Yb)(N) ratios of magmatic rocks along the Cenozoic Urumieh-Dokhtar and Alborz magmatic belts, Iran. Both the magmatic belts are located at the north of the main ...
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 ...
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) ...
