Age and compositional evolution of Sahand volcano in the context of post-collisional magmatism in northwestern Iran: Evidence for time-transgressive magmatism away from the collisional suture

The Van Microplate: A New Microcontinent at the Junction of Iran, Turkey, and Armenia

“…The first group includes adakite and adakitic rocks, and the second includes high-Nb, basaltic rocks (Jahangiri, 2007;Azizi et al, 2014a;Azizi et al, 2014b), which confirms that they were formed in a postcollisional, tectonic regime. In addition, some of the major Pliocene-Quaternary volcanoes, such as Sahand, Sabalan, and Ararat, erupted at this time (Allen et al, 2013a;Chiu et al, 2013;Ghalamghash et al, 2019).…”

“…We have compiled whole-rock, chemical data on 900 volcanic rocks (Agostini et al, 2007;Jahangiri, 2007;Azizi and Jahangiri, 2008;Haghnazar and Malakotian, 2009;Mazhari et al, 2009Mazhari et al, , 2011Ahmadzadeh et al, 2010;Dilek et al, 2010;Ranin et al, 2010;Aghazadeh et al, 2011;Aghazadeh et al, 2015;Ansari et al, 2011;Dabiri et al, 2011;Hajialioghli et al, 2011;Mahmoudi et al, 2011;Asiabanha and Foden, 2012;Alishah et al, 2013;Ansari, 2013;Castro et al, 2013;Ghaffari et al, 2013;Kheirkhah et al, 2013;Moghadam et al, 2014;Neill et al, 2015;Doroozi et al, 2016;Haghnazar et al, 2016;Moritz et al, 2016;Sahakyan et al, 2017;Taki, 2017;Ashrafi et al, 2018;Haghighi Bardineh et al, 2018;Jafari Sough et al, 2018;Lechmann et al, 2018;Shafaii Moghadam et al, 2018;Zhang et al, 2018;Ghalamghash et al, 2019;Temizel et al, 2019) from Cretaceous to Quaternary magmatism in northwestern Iran, southern Armenia, and eastern Turkey (Supplementary S2). The sample locations and references for each area are shown in Figures 4A-E.…”
