“…Magmatic detrital zircons of this age also show peaks in the Early‐Middle Permian strata of the Khanka Massif, such as the 479 Ma age peak in the Early Permian Dasuangou Formation and the 493 Ma age peak in the Middle Permian Jiefangcun Formation in Yanbian (Chen et al, 2014; Wei et al, 2020). However, the Khanka Massif lacks contemporaneous magmatic activity (Khanchuk, Sakhno, & Alenicheva, 2010; Khanchuk, Vovna, et al, 2010; Xu et al, 2018). On the contrary, igneous rocks of 490–470 Ma are widely distributed in the Jiamusi Massif, such as the diagenetic age of 492 ± 6 Ma granite gneiss and 488 ± 2 Ma granite in the northern Luobei area (Han et al, 2020; Li, Zhou, & Li, 2020), 488 ± 3 Ma granite in the eastern Baoshihe area (Bi, 2015), and 492 ± 6 Ma granite gneiss in the Western Yilan area, 499–476 Ma I‐type granite in Mishan‐Jidong area in the South (Yang, 2017), 490–476 Ma gneissic granite in Boli area in the South‐west (Yang, 2017; Yang et al, 2018), 486 ± 3 Ma granite in Muling area (Xie, Miao, et al, 2008) (Figure 10).…”
