Geophysical Research Letters, 2023 We present two robust and well‐dated paleomagnetic poles from upper Eocene and Oligocene volcanics in the Urumieh‐Dokhtar magmatic arc, Central Iran. These two poles place Iran ∼3.7°–3° of latitude south of its present position between ca.

Geochemistry and petrogenesis of mafic and intermediate dyke swarms in eastern Tafresh (Urumieh-Dokhtar magmatic belt) [PDF]
پترولوژیIntroductionThe Urumieh-Dokhtar magmatic belt is one of the most active magmatic regions of Iran during the Cenozoic era. There are differing views regarding the tectonomagmatic setting of this magmatism; some attribute it to active continental margin ...

Lithos, 2017 The Urumieh-Dokhtar magmatic belt of Central Iran runs parallel to the Zagros orogenic belt and has been resulted from Neotethys ocean subduction underneath Eurasia. The Bahr Aseman volcanic-plutonic complex (BAC), covering an area ~ 2000 km^2 in the Kerman magmatic belt (KMB) in the southern section of the Urumieh-Dokhtar belt, has long been ...

Biostratigraphy and Microfacies of Qom Formation in Urumieh – Dokhtar Zone, Iran [PDF]
International Journal of Engineering and Technology, 2018 In order to determine the accurate paleoenvironmental conditions of Qom Formation, one stratigraphic section was studied in the Urumieh-Dokhtar Zone (West of Ashtian). 60 thin sections of the Qom Formation, 71 m thick, were prepared and the distribution of benthic foraminifera was analyzed.
