A Showcase of Igneous Processes in the Urumieh-Dokhtar Magmatic Arc: the Miocene-Quaternary Collisional Magmatism of the Bijar-Qorveh Area, Northwest Iran

open access: yesJournal of Petrology, 2022
Abstract The Cenozoic Arabia–Iran continental collision was associated with emplacement of a large variety of magmatic rock types. This aspect is particularly evident in the Bijar-Qorveh area of NW Iran, where Miocene andesitic to rhyolitic rocks and Quaternary basic alkaline rocks crop out. The Miocene intermediate to acid products show
