“…An Andean‐type arc setting could plausibly account for their petrogenesis (e.g., Li et al, ; Tang et al, , ). In the modern Andes, active continental margin low‐angle or flat‐slab subduction occurs, and the following observations also indicate the existence of the low‐angle or flat‐slab subduction during the Triassic for the southwards subduction of the Mongol–Okhotsk oceanic plate: Late Triassic I‐type granite (Arynnur granite; Jiang, Nie, Su, Cai, & Ding, ; Liu et al, ), A‐type granites, and bimodal volcanics (Baga–Gazriin granites; Olzit granites, basalts, and rhyolites; Kharkhorin basalts and rhyolites; Yarmolyuk et al, ; Machowiak & Stawikowski, ; Machowiak et al, ; Ochir & Dostal, ; Dostal et al, ; Zhu et al, ) crop out in the Central Mongolia Massif (Figures a, , , and a), which is located approximately >200 km (Olzit, Tumurtin Ovoo, Arynnur, Badaguan, Shanghulin‐Mordaoga; Figure ) south‐east of the Mongol–Okhotsk Suture Zone. Such a long distance requires long‐lasting low‐angle or flat‐slab subduction.…”
