“…In the Iran region, the tectonic boundaries of the continental blocks that make‐up the hinterland domain of the Zagros convergence zone record a prolonged history of deformation and reactivation since Neoproterozoic times (Bagheri, Madhanifard, & Zahabi, ; Kargaranbafghi, Foeken, Guest, & Stuart, ; Nozaem et al, ; Ramezani & Tucker, ; Rossetti et al, ; Tadayon et al, ; Verdel et al, ). Such tectonic zones are presently dominated by wrench tectonics that accommodates and transfers the intraplate residual convergence transmitted from the collisional boundary across the Central Iran region (the assembly of the tectonic zones known as Central Domain and the Central‐East Iranian Microcontinent [hereafter referred as CEIM]; Figure ) (Khodaverdian, Zafarani, & Rahimian, ; Nilforoushan et al, ; Vernant et al, ; Walpersdorf et al, ), in response to a geodynamic scenario dominated by ~N–S‐directed convergence since at least 52 Ma (Berberian, , ; Berberian & Yeats, ; Jackson, Haines, & Holt, ; McQuarrie et al, ; Nowroozi & Mohajer‐Ashjai, ; Walker & Jackson, ).…”

A better understanding of intraplate deformation requires the knowledge of the space–time scales involved in its development and to decipher possible links with the dynamic evolution of the plate boundaries. Central Iran provides an ideal test site to approach this scientific issue, since it is characterised by a prolonged history of Mesozoic–Cenozoic intraplate deformation that has been interfering with the spatio‐temporal re‐organization of the Zagros convergence zone along the Eurasia plate boundary. This study focus on the Doruneh Fault (DF) region that is considered as the northern mechanical boundary of the Central East Iranian Microcontinent. By combining field investigations with apatite low‐temperature thermochronology, we present a revised tectono‐stratigraphic scenario for the DF region, typified by a punctuated history of fault‐related exhumation, burial and cooling history back to the Upper Cretaceous. When framed at regional scale, these results attest that the Zagros convergence zone, and its hinterland domain were fully mechanically coupled since ca. 40–35 Ma, a time lapse that is here referred as to the onset of continental collision along the Arabia–Eurasia plate boundary. In this scenario, the DF region operated throughout the Cenozoic as a major zone of residual stress accommodation and transfer in the hinterland domain of the Zagros convergence zone. Results of this study also suggest that the tectonic evolution along the Arabia–Eurasia plate boundary was modulated by the plate‐boundary dynamics and by the modes of tectonic reactivation of the intracontinental weak zones of Central Iran and at its tectonic boundaries.

“…Late Neoproterozoic-Early Cambrian ages of inherited zircons (610.3 to 522.9 Ma) from the study area, and other regions in the Central UDMA (Babazadeh et al, 2019;Chiu et al, 2017;Shahsavari Alavijeh et al, 2019) indicate a basement for this zone. The crystalline basement of Iran that includes Late Neoproterozoic-Early Cambrian granodiorite, granitic gneisses, gabbro, and associated volcanics is considered as Iran's continental crust (Hassanzadeh et al, 2008;Jamshidi Badr et al, 2013;Karimpour et al, 2011;Ramezani & Tucker, 2003;Rossetti et al, 2015;Shakerardakani et al, 2015). The Neoproterozoic inherited zircons from the UDMA are comparable to the magmatic zircon ages in the SSZ, Central Iran, and northwest Iran (e.g., Nutman et al, 2014;Shahzeidi et al, 2016;Shakerardakani et al, 2015;Figure 7c, d).…”

“…The affinity of Neoproterozoic magmatism to subduction of the Proto-Tethys Oceanic Plate beneath the northern margin of Gondwana has been considered by some authors (e.g., Chiu et al, 2017;Rossetti et al, 2015) as representing the Cadomian Orogeny, whereas others (Stampfli, Hochard, Vérard, Wilhem, & von Raumer, 2013;Von Ramuer, Stampfli, Arenas, & Martínez, 2015) consider the Late Neoproterozoic-Early Cambrian ages as being derived from NE Gondwana-Shan South Chinese region.…”

Laser ablation ICP‐MS U–Pb dating on inherited zircons from Neogene volcanic rocks of the Tafresh area in the central part of Urumieh‐Dokhtar Magmatic Arc (UDMA) yielded Paleoproterozoic, Late Neoproterozoic–Early Cambrian, Carboniferous, and Cretaceous ages. These ages improve our understanding of the geodynamical evolution of central UDMA. The 2,379 Ma age (i.e., Paleoproterozoic) is the oldest age reported in the central UDMA and is similar to the age of detrital zircons from Central Iran. The Paleoproterozoic zircons may come from the African Craton and fed from Central Iran sedimentary sequences. The Late Neoproterozoic–Early Cambrian ages (605 ± 11 Ma to 533 ± 9.2 Ma) indicate a basement for the UDMA, which is similar to that of the Sanandaj‐Sirjan Zone, Central Iran, and northwest Iran. The Carboniferous zircon age (328.4 Ma) is interpreted as being derived from the Eurasian arc produced by northward subduction of the Paleo‐Tethys Oceanic Plate. The Late Cretaceous zircon ages (106 to 71.2 Ma) might be regarded as indicating the Late Cretaceous magmatic episode, marking the subduction of oceanic crust that followed the Neo‐Tethys subduction.
