“…2.1 Ga, A-type granite in the Central Orogenic belt is well documented, such as the Huangjinshan granite (2137 ± 9 Ma) of the Wutai massif (Du et al, 2013), the Dawaliang granite (2170 ± 17 Ma) of the Wutai massif (Du et al, 2018), the Nanying, Gangnan and Baiyangling granite gneisses (2080-2070 Ma) of the Fuping massif (Wang et al, 2020), the Lingyunkou granite (2080-2050 Ma) of the Hengshan massif (Zhao et al, 2011), the Chijianling-guandimiao granite gneiss (2180-2130 Ma) of the Luliang massif (Liu et al, 2021), the Tongkuangyu meta-acidic volcanic (2143 ± 11 Ma) of the Zhongtiao massif (Yang et al, 2015) and potassic granite (2194 ± 29 Ma) of the Lushan massif (Zhou et al, 2014). A-type granite is not only restricted to the Central Orogenic belt, but also occurs in the other parts of the North China craton, such as the Hupiyu monzogranitic gneiss (2180-2150 Ma), the Simenzi granite (2163-2180 Ma), the Muniu monzogranitic (2168 ± 30 Ma) of Liaoji area in the Jiao-Liao-Ji orogenic belt (Chen, Yang, et al, 2021;Chen, Zhu, et al, 2021;Liu, Tian, et al, 2020;Zhu et al, 2019), the Chang'e granite (2193-2171 Ma), the Muniushan monzogranitic (ca. 2110 Ma) and Jingqishan granite (2123-2088 Ma) of the Jiaobei area in the Jiao-Liao-Ji orogenic belt (Cheng et al, 2017;Lan et al, 2015;Zhang, Liu, Xu, et al, 2022), and the Shimenshan granite (2096 ± 9 Ma) and Fengyang granite gneiss (2096 ± 8 Ma) of the Wuhe Group of the Anhui area of the Jiao-Liao-Ji orogenic belt (Wang, Liu, Zhang, Zhao, Wang, & Song, 2017).…”
