Neogene Tectono‐Stratigraphic Evolution of the Intermontane Tarom Basin: Insights Into Basin Filling and Plateau Building Processes Along the Northern Margin of the Iranian Plateau (Arabia‐Eurasia Collision Zone)

Abstract

• The red beds of the Tarom Basin are > ∼ 16.2 to < ∼7.6-My-old and are stratigraphically equivalent to the Upper Red Formation • Over the last 38-36 Ma the basin experienced alternating stages of internal and external drainage without being integrated in the plateau • Deep seated processes rather than shortening and thickening are responsible for the vertical growth of the Iranian plateau margin Accepted Article This article has been accepted for publication and undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.

Low‐Temperature Thermochronologic Response to Magmatic Reheating: Insights From the Takab Metallogenic District of NW Iran, (Arabia‐Eurasia Collision Zone)

“…Plateau uplift occurred sometime after the ∼17 Ma regional marine regression (top of the Qom Formation e.g., Ballato et al., 2017). The NW sectors of the plateau are characterized by a contractional basin‐and‐range landscape that started developing in the middle to late Miocene in response to collisional shortening and thickening processes (Ballato et al., 2017; François et al., 2014; Mouthereau et al., 2012; Paknia, Ballato, Heidarzadeh, Cifelli, Hassanzadeh, et al., 2021). The TRC constitutes a major mountain range within the plateau interior at the boundary between the metamorphic SSZ and the UDMZ (e.g., Stöcklin, 1968; Figure 1).…”

Slab Folding and Surface Deformation of the Iran Mobile Belt

“…10.1029/2020TC006300 10 of 25 François et al, 2014). The initial stages of collisional deformation affected also the Talesh-Alborz area, with diffuse Oligocene basin inversion followed by a diachronous acceleration in shortening and exhumation rates from the early-middle Miocene to the Pliocene (e.g., Ballato et al, 2011Ballato et al, , 2015Guest et al, 2006a;Madanipour et al, 2013Madanipour et al, , 2017Paknia et al, 2021;Rezaeian et al, 2012).…”

“…Since the latest Eocene, the TAK has started recording transpressional deformation together with exhumation most likely as a far-field effect of the earliest phases of the Arabia-Eurasia collision (e.g., Allen et al, 2003;Ballato et al, 2011;Guest et al, 2006bGuest et al, , 2007Lyberis and Manby, 1999;Madanipour et al, 2013;Rezaeian et al, 2012;Robert et al, 2014). Subsequently, from the early-middle Miocene, exhumation rates increased significantly possibly in response to a more advanced stage of the Arabia-Eurasia collision (e.g., Axen et al, 2001;Ballato et al, 2013Ballato et al, , 2015Guest et al, 2006bGuest et al, , 2007Madanipour et al, 2017;Paknia et al, 2021;Rezaeian et al, 2012). To the north, the South Caspian Basin appears to have started subducting beneath Eurasia at least from the late Miocene (e.g., Mammadov, 2008), possibly when the TAK range started bending around the South Caspian Basin (e.g., Cifelli et al, 2015;Mattei et al, 2017) or following the rapid sediment loading triggered by the ∼ 6 to 3 Ma, km-scale (0.6 to 1.4km) base-level fall in the Caspian Sea.…”

Neo-Tethyan subduction triggered Eocene–Oligocene magmatism in eastern Iran

“…1). The Iranian Plateau represents the second largest collisional system in elevation and size after the Tibetan Plateau (Paknia et al 2021). During the Cenozoic, extensive magmatism occurred throughout the Iranian Plateau.…”

“…On the other hand, after the collision between the Lut and Afghan blocks, a post-collisional tectonic setting has been proposed to generate the EIMB igneous rocks (e.g. Pang et al 2013;Sepidbar et al 2018;Omidianfar et al 2020). Alternatively, some studies attribute the EIMB magmatic rocks to an Andean-type active continental margin due to subduction of the Sistan Ocean underneath the Lut block (e.g.…”
